I have a Hayward HP11002 I need to replace. Is this unit the same foot print / size to replace with?
Hi, Frank. This HP21104T will have the same footprint.
How many gallon pool will this heat efficiently.
Hi, Thomas, This unit can heat about 20,0000 gallons of water efficiently.
is this a suitable replacement for Hayward Heat Pro Heat Pump HP21002. Hoping to find the exact "plug and play" replacement so I can replace the old unit without much heartache.
Hi, Mickey. This will be the closest replacement that is available that will meet your needs.
What is the normal life expectancy HP211047? I am on my second unit in 10 years. The first unit developed a leak in the coil two days after the warranty expired. Hayward went ahead and replaced it but would not give me a warranty on the replacement. Now the replacement unit has developed a rusted connection on the heat exchanger. I'm told by the Hayward Tech that it would be cheaper to replace the unit rather than repair it. Not so sure I want to replace it with another Hayward.
Rick, It is difficult to say as there are a lot of factors that can play a role in life expectancy. On average, I would say 5-10 years depending on usage and maintenance.
Need to replace a HP21002 for a18,000 gallon in-ground pool. What size heater would you recommend? Do you recommend oversizing it and putting in the HP1404T or the HP21104T? Or should we go in the middle with the HP21254T?
I am replacing my Hayward 2100 - is this a drop in replacement?
Hi. This unit will be the closet but not a drop-in replacement.
I presently have an HP2100. Will this model directly replace this with unit with a 50 amp breaker?
Good day, yes this unit would be a match as the replacement for that unit and will require the same amp size.
Does this unit have 50 watt or 60 watt service? Thanks .
Hi, Brian. This unit requires a 50 amp, 230 volts, single phase breaker.
I just bought the Hayward heatpro 110 btu. What size wiring is recommended to install it?
Hi, Ronda. You will need to consult an electrician, the wire size will be based on the distance from the breaker and the unit.
I presently have a 110k BTU on my 16x36x4ft pool....would it be worth replacing with the 140K BTU or just go with another 110k BTU??
Considering the pride difference not being too drastic I would go with the 140k. It will heat the water quicker hence putting less strain on the unit.
Just want to make sure that the connections from my 20854T are the same as on the 21104T so we can just swap the units and everything will work the same. Thanks
Good Morning, Yes this will be an exact replacement.
I have a 20,000 gallon in ground pool. My Hayward HP21002 is shot. Will this heat the water eefficiently and an easy replacement as far as the water piping and electrical? It looks like the same height and piping as the 21002.
LOOKING TO REPLACE A HAYWARD 20854T HEAT PUMP. WHICH WOULD YOU RECOMMEND? 15X30 ABOVE GROUND POOL THANKS!
Hi, Jeannine. This HP21104T will be the recommended replacement for the HP20854T model.
Could I install this unit within an existing Pool Shed? I have a ~8 x 8 pool shed where my Pool pump/filter is currently housed and have plenty of room to install this near the pump. Since this is not a natural gas heater that would emit heat, is there any risk to installing this within a vented wooden shed?
Placement / Clearances All criteria given in the following sections reflect minimum clearances. However, each installation must also be evaluated, taking into account the prevailing local conditions such as proximity and height of walls and public access areas. The heat pump must be placed to provide clearances on all sides for maintenance and inspections. 1. A minimum of 24 in [61 cm] of clearance on all sides. 2. If the heat pump is to be installed under a cover or vertical overhang, the unit must have a minimum of 72 in. [183 cm] of clearance from the top of the heat pump to the bottom of the cover or overhang. 3. Install the heat pump a minimum of 60 in. [1.5 m] from the inside wall of the pool, spa, solid fence, or permanent barrier
looking 4 110000 btu heat pump above
Hi, Ken. We do have 4 of these units available.
I have an HP21002 from June 2005. It is not heating the water. I think it is time for a new unit. What is the best same replacement for this unit? The installation should be easy if it is a complete replacement. I live on Long Island, NY. I have a 16x40 inground.
Hi Dianne, If you are replacing an HP21002 then this HP21104T would be the best and closest replacement. The installation should be pretty straightforward and easy since you are replacing an existing heat pump.
Good afternoon I'm looking to get the 140,000 btu hayward heat pump. Do u have this item in stock. I have 60 amp if electric in my pool house. This includes my filter tv radio lights etc. is that enough amps to run this heater? Thank you
Yes, a 60 amp circuit is sufficient for this unit but will need its own designated circuit.
What is the part that looks like a nut on the elbow of the return pipe? What does it mean when this part is spurting water? Many Thanks, Leslie
Hi, Leslie. I'm not sure what part you're referring to. If water is squirting out if it, it has cracked. Use the HP21104T Part Diagram to point out the part you're talking about and where the water is leaking from.
hey, i have a 16000 gal concrete pool. do you think the heatpro 110 000 btu would be able to heat my pool. i live in nj.
Yes, the Hayward Heat Pro Heat Pump 110,000 BTU is sufficient for operation of a 16,000-gallon pool. *Heat pumps operate best in humid environments.
How quiet is this unit when running ? For comparison, the Aquacal is rated at 55db. Also, which is the better unit overall - the Hayward of the Aquacal ?
Hello, Hayward does not list the exact decibel of these units, but the HeatPro-Brochure implies that these units are under 60 dB. In comparison, they are both great units, but the warranty on the Aquacal is better depending on what state you are located in.
Will this heat pump work with a Jandy Aqualink RS4? Do you charge sales tax to FL?
Hi, Don. This unit can be wired to your Jandy Aqualink RS4 Controller. Sales tax will be applied if the unit is being shipped to an FL address.
I have an inground 12,300 gallon salt water pool and live in SW Florida. Will a 110,000 BTU heater suffice?
Hi, Bill, Yes, this Hayward Heat Pro Heat Pump 110,000 BTU will be adequate to heat a 12,300 gallon pool in SW Florida.
I currently have solar and natural gas heat. Would it be worth my time and money to switch out to an electric heat pump? I would need the 110k since my pool is 14,100 gallons.
Hello, heat pumps are a lot more efficient than gas heaters and have much lower operating costs, but they only work well in temperatures over 50 degrees Fahrenheit.
Does pump turn on automatically at 32 degrees? Pump was off but Turned on with very cold weather this morning.
Hi, Jim. The heat pump will turn on when the main pump turns on. If you have freeze protection then the pump will turn on when the temperature drops to freezing, however, this heat pump will not operate at 32 degrees.
reads DEF and will not come on
Hi, Richard. The unit's evaporator coil is defrosting. The unit will not operate until it is defrosted.
WHAT ELECTRIC IS NEEDED FOR 110000 HEAT PUMP
Hi, Terry. This unit requires a 50 (min) or 60 (max) amp 230 volts breaker.
I'm in Mesa, AZ with approx 15-16k inground pool and just bought the 50k Hayward heat pump and it works but I am worried it might not be enough for the spring and fall. I may return it (locally) and try buying from you guys but I'm not sure what size I should get. 110, 125, 140. I already have the plumbing for the square design but it's not a big deal to change it. I would like to be able to swim march-November. Ambient temps are 70-80's in march and November. Thanks!
My heat pump is not running and flashing LP which I looked up and is the Low Pressure switch. Does the switch need to be replaced or are there other things we can do first to try to fix it?
Christine, There are a few causes for the LP error. Page 4 of the troubleshooting guide will walk you through what to look for.
Is this pump all electric and can I use this for an above ground pool?
Hi. This Heat Pump does require a 50/60 amp 230 volt electrical connection and can be used to heat an above ground pool.
What size hearted is needed for a 16 by 32 inground pool?
Hi. This heat pump can be used to heat a 16' x 32' inground pool, however, geographical location, desired pool temp, and runtime will determine the size of the unit you need.
Flashing LP 74 What does this reference
Hi, Joe. LP is the error code for Low Pressure Switch which is caused by an Air flow obstruction.
this unit need a 20amp 220 circuit breaker. I have a 15 foot by 30 foot by 52 inch pool. located in NY Long Island, looking to heat water to 85 degrees during summer months. Thank you,
Hi, Michael. This unit requires a 50 or 60 amp 230 volt breaker and would be able to keep your pools at 85 degrees during the supper months.
Is this the size heat pump I would need for my 27 round, 52 inch above ground pool?
Hi Rose, Yes this would be the size I would suggest for a 24' Above Ground Pool
Replacing an old "Air Energy" electric heat pump........pool size is 35/60 feet and 29,000 gallons.......Old unit is 118,000 BTU..........not sure if this is what I should replace it with..........What Hayward Heat Pump would you suggest ? Thank you
Hi, Schlehofer. I would recommend the 125,000 BTU - HP21254T unit.
I have a 12 X 30 pool which averages 4.5 ft deep. It has a baja deck which is only about 2.5 ft deep and measures 8 X 8. I have a sola cover for it. I live in AZ and get full sun most of the day the way the pool is located. I want to maintain the pool about 85 degress and I would like to extend my swimming season to at least 10 months out of the year. Would this 110K unit be the best one for me?
Hi Russ, since you are wanting to do this for 10 months out of the year then I would suggest a larger unit like the Hayward 140,000 BTU Heat Pump
What size heat pump do I need for a 27 round above ground pool?
This 110,000 BTU Hayward heat pump is what we suggest for a 27' Round Pool
Hi. Our Hayward heat pump pool filter Model No. HP2100TCO2 has served us well for 12 (+/-) years, but the fan has become annoyingly loud. Any merit in refurbishing? Or just replace? Bill Mayer
I bought the hayward heat pump and turned it on to start heating the pool and it has not raised in temperature from 64 degrees. The setting is at 80 degrees, is there something I need to do?
Hi, Gabe. I would recommend contacting Hayward at 908.355.7995 so that they can send a technician out to check out the unit to find out why it's not heating if an error code is not displayed.
Do new pool heat pumps come PRE-CHARGED? also if i (consumer) does install..(i am electrician) ..will it void any warranty? thanks for assistance
Hi, Pete. These units do come pre-charged. The unit has to be installed by a licensed professional. Since you're an electrician you can do that part but not the plumbing portion.
Hello, What is the kilowatts for this heater?
Hi, Blupools100. The input kilowatts of the unit is 6.2.
The product page says this is 110k BTU, but the photos say HP50TA, which is a 50k BTU unit. Which one is it?
Hello, the HP21104T is a 110k BTU unit, the picture is just to give you an example of model numbers and description of how label will look.
I live in Tucson AZ and am looking to use a heat pump from may-sept. pool is 16,000 gallons, 480 surface area. I think the correct heat pump is the Hayward Heat Pro Heat Pump 110,000 BTU - HP21104T What is your opinion?
Hi, Jack. The 110K BTU unit is sufficient to heat a 480 sq. ft. pool. I would recommend that you start with next size up whcih is the 125K BTU unit HP21254T.
I live near Chicago, IL and am looking in to what size heat pump i may need for an 18' x 33' oval above ground pool. would 125,00btu be large enough, or would a 140,000 btu model be neccessary? Thanks in advance!
Hi, Bob. I would recommend the 140K BTU unit.
does the HP31204T have cooling ?
Hi, Mike. Inyo does have the Hayward Heat Pro Heat Pump 120,000 BTU Heat/Cool - HP31204T available.
I see the recommended rate of flow is 30-75 (HeatPro 110 BTU)aside from an expensive flow gauge how can one tell the rate of flow to have the pump perform properly ?
Hi, Mark. You can calculate the flow rate manually using the steps in our How To Size a Pool Pump which will put you close but a flow meter will much more accurate.
I have a 30 foot round 54 in. sidewall above ground pool. Would this unit work for me? Local pool places say a heat pump is not a good idea for my size above ground pool because of my surface area and that I should only look at Gas heaters. I have friends with in ground pools that use propane and say the price of the gas use makes it not cost effective over the season so they cant even afford to use them. I live in central Ohio. Thanks!
For that size of pool and your location I recommend the 140,000 BTU model, HP21404T. Running that heat pump from May through August with a run time of 8 hours a day you would be looking at about $130 for the month of May due to the initial heating cost and then June through August would be $40-70 per month.
What are the pros and cons of using a cover similar to a grill cover for a heat pump located under a roof edge and subject to North Florida rain and sun effects?
If it fits there is anything wrong with using a grill cover for your heat pump.
Should i let pool water circulate through my heat pump when I am away for a while and heat pump is turned off?
Hi. I would not recommend doing that. If you do not have a bypass installed then you have no choice but to.
What is the difference between the HP21254T and the HP21104T heat pumps ? What size pump will work best for a 16 x 32 x 5' deep in ground pool ?
With your pool size you will want the 140,000 BTU model, HP21404T.
I have a new 24' x 52" round pool being installed, I am 15 miles north of Boston, MA. It will also have a saltwater chlorine generator, I am looking for the right heat pump to install, I was looking at the Hayward HP21004T or the HP21104T. You have the best prices and after reading other reviews quality of service. Thank you
For the location you live in I would not recommend a heat pump less than 125,000 BTU's, part number HP21254T.
I have a 14 by 28 ft. pool going from 3.5 to 6ft. I live in Florida. What size pool pump would I need ? The 95,000 or 110,00 BTU? Thanks
You could be with either one, but the 110,000 BTU unit is going to be the most efficient unit for you pool size and location.
I have 12 by 24 inground pool an it 3to6 deep. Which heater is good for my pool. I livr in Florida
You would be good going with the 95,000 BTU model, HP21004T, but the 110,000 BTU model would be efficient as well.
Does this price include Fl tax? My current heat pump has 13" clearance to the rear. Will this be a problem for the Hayward hp21104t?
The current advertised price of $2,476.99 does not include Florida's State Sales Tax. You may add the item to the cart and enter your zip code, it will provide the tax for the heat pump or any other items. According to the owners manual on page 8 of 22, it states, A minimum of 2 feet (.6 m) of clearance from walls, shrubbery, equipment, etc. is required around the entire heat pump. This allows for ample air intake. A minimum of 6 feet (2 m) of clearance above the heat pump is required to prevent re-circulation of air. The unit should not be placed underneath eaves, decks, or porches, as this causes re-circulation of air.
Is a 110btu enough for a 13x33 3 to 6 foot deep kidney shape
Yes, the HP21104T is big enough for your size pool.
I have a 16 x 32 inground pool with an avg depth of about 5'-6'. I live in Long Island, NY, which unit would be best for me? I was thinking the 110,000 but might go with a 140,000. Thanks in advance.
With a pool 19,000-20,000 gallons and the location you live in I would recommend the 140,000 BTU model, HP21404T.
who is your dealer or installer for the Easthampton, NY area?
We ship all product from our vendors across the country and unfortunately cannot provide that information. These vendors sell only to businesses. You may be able to get those lists if you have a qualified business license/permit for a related industry.
how to replace temperature sencor
Hello Carlos- Unfortunately we do not have this information. We recommend contacting Hayward's tech support at 908-355-7995.
I live in Central Florida and I have a 35000 gallon pool. How big of a heater will I need for my pool?
You will need the 140,000 BTU model, part number HP21404T. It will take a couple of days of continuously running the pump to get the water to your desired temperature but once it there that heat pump will regulate the temperature from the preset temperature of your choosing.
what size electrical panel breaker is needed for the 110,000 BTU heat pro heat pump. Does this need to be a ground fault breaker?
Hi Gene, This unit requires a 60 amp breaker that should be ground fault which is NEC code compliant.
Just tried to turn my heater on in Florida and the code OP came up.. Any ideas?...
According to the Hayward Heat Pro Heat Pump Owners Manual, the OP code indicates a temperature sensor failure, part #HPX2169. If you have additional questions regarding this issue, feel free to contact Hayward directly at 1-800-657-2287.
Hi i live in Las Vegas and I'm surprise they don't install the heater pump here its like no one knows that exist. Anyway i try to understand why and some answer is the concern about the very low humidity here. So is the humidity an issue to have those system working correctly ?
That is not a problem. I use to live in Coachella Valley which is the desert just like Las Vegas and I had a heat pump/chiller for my pool which is what I would recommend. In the summer months where it is 120 every day you will want the chiller part on your heat pump and then with the winter months you will be happy you have your heat pump.
I have a Hayward HP21104T heat pump the LP trouble code is on. Is this the low pressure switch bad or low freon causing this?
Good morning Brian, It could be either. The code will show for both. I would check the Freon level first. If the level is good then it is the switch.
We live in Florida, our pool is screened in so it doesn't get as warm as we would like. What size hayward heat pump do need to heat a 15000 to 16000 gallon in ground pool?
Good morning Trudi, The 110,00 Btu's will work good. But you could use the 140,000 Btu's and it would run less.
is this model also a chiller?
Hello- This model does not heat and cool the pool. I would recommend this model, Hayward Heat Pro Heat Pump 120,000 BTU Heat/Cool - HP31204T, to accommodate your heating and cooling options.
Is the HP21104T suitable for a 13000 gal pool
What state do you live in, that will play a factor as well?
Hello, we are looking for an electrical water system for our salt system in ground outside pool. The size is 16x20, 11,000 Gal and 7 Ft max. We have a Hayward pump, please let us know what system do you recommend. Thanks
That would be efficient for the size of your pool. I would not go any smaller than the 95k model.
Hello, we live in Arizona so yes its gets Hot !!!. Looking for a heat pump that will Heat in the winter and cool down in the summer months, pool size is 39' x 25' x max depth of 7 ft.. so I'm thinking we would need at least 108,000 btu . ?. Pentair/aqua pro/raypak/Jandy . What is recommended ? by looking at the pricing may have to finance lol. thank you
The Pentair Ultra Temp, 460935, is a great model for the price as well as the RayPak, 013336. I used to live in the desert in Palm Springs, CA where as you know gets to 120 degrees everyday during the summer months. The chill feature on my heat pump was amazing. I would go to the gym for an hour, come back to jump in the pool and in that time frame it was nice and cool. I had the AquaCal, SQ120R, and in my 14 years of being in the pool industry it has been hard to find a heat pump at that caliber. If you have any further questions don't hesitate to email me back.
Thank you for your quick response to my question regarding the shape of the Hayward HP21104T heat pump. If I may, please double check to make certain that this unit is square as pictured on your web site. I ask because all of other web sites show it as round and Hayward's installation guide shows it as round. The square units seem to bee the 100K btu, the 125K btu and the 140Kbtu units. The 110K units seems to be round. Could there be two styles of this unit?
I apologize Ken for the false information, I have someone changing it right now. Out of the HeatPro heat pump models, the only one that is round is the 110,000 BTU model, HP21104T. All the rest are going to be square.
The picture of the HP2110T on your web site shows a square unit. Isn't this model a round unit?
This model is a square shaped unit.
On 6/20/2016 Scott indicated in an answer that from a quality and endurance he would lean towards the RayPac over the Hayward. I was wondering if he could expand on the differences. Heat Pump replacement is no something I want to be doing on a regular basis.
Raypak specializes in heating and cooling units. When it comes to replacement parts, in my experience, get an abundance of calls more on the heat pro than the Raypak. In my experience, I have seen personally the Raypak be more durable than the heatpro. Both great heat pumps, just letting you know what I have noticed and experienced.
What brand of compressor is in a Hayward Heat Pro Heat Pump 110,000 BTU - HP21104T? Is it a Copeland compressor?
Hi, Jon. We're unable to get the actual manufacturer of the Hayward compressor. We do no have this item in-stock at the warehouse to check.
I had a inspection on my Hayward Heat Pump and a error code came up P-5. Can you explain to me what that code means?
Hi Brian, The PS error code refers to the water pressure. Either the unit is not getting adequate water flow or the water pressure switch is bad.
I live on the south shore of Long Island NY close to the water. I was looking to see if a 140k BTU electric heat pump would work with our different climate change. I keep get conflicting answers from different pool companies
Hi Monte, Heat Pumps can be used in you geographical location, however, once the temperature drops below 50 degrees it becomes insufficient.
Hello, I wanted to check and see if this unit will be sufficient for my pool. I live in South Florida, have a freeform small 10,000 gallon pool with the following equipment: - hayward 1 1/2hp super pump - hayward 48 sq ft DE filter - hayward salt cell
Hi Corey, This Hayward Heat Pro Heat Pump 110,000 BTU is sufficient for your pool based on the pool size.
I hhave a 36000 gal pool which inludes a 800 gallon hot tub. The hot tub is isolated when used. will the 110,000 BTU version hold the pool at 82 and when I want to use the hot tub at 102? I live in NH where the nights cool down.
Hi David, I will recommend the HP21404T unit instead along with a solar cover based on the info provided.
what is minimum gallons per minute input requirement I know there is one as spec says it will shut down
The minimum flow rate is 30 GPM (gallons per minute).
I have a haywood pool heater hp21104tc with a haywood pum[ 4 speed variable and a haywood de filter.With the pump set continually at 3300 why does P5 show up a few hours after backwashing? Have backwashed 4 times in the last 2 weeks yet P5 still comes up. The pump and heater are brand new.
Hi Tim, The filter media may need to be replaced or thoroughly cleaned.
i have a haywood titanium heat pump with a haywood variable speed pump does the pump have to be at maximim rpm to make the heat pump run? if so should I have gotten just a single speed pump 1 1 /2 HP pump?
Tim, Depending on the pump model, you will need to increase the rpms when you need to use the heater. It doesn't necessarily have to be at max rpms.
My heat pump turns on and will heat the pool to 84 that what I want but it will not maintain the temp. It is not kicking on and off I have to turn it on ever time what am I doing wrong
Hi, The unit may need to be inspected to find out why the unit is not heating automatically.
On this 110k heat pump do you need "2" 3 way valve 1.5x2 NVR LUBE or just one for installation
Hi Jonna, You will need (1) 3 Way Valve, (1) 3 way tee and a check valve to install this unit.
What size heat pump would be best for a 27K Gal 36 L & 26&17 width - 9 feet deep end and 3.5 feet shallow. Which Heat Pump and what is the best price?
Hello. I have a 27' round above ground pool. Which unit will I need to properly heat it? I am in NJ. Thank you.
The 110,000 would work fine for your pool, the 125,000 would get the job done faster which would save you money.
Good morning I need to have the exact shipping weight and crate dimensions since i need to export this product by air to Mexico. I appreciate your prompt response Martin Bossler
Hi Martin, The shipping weight of this unit is 230 lbs. Shipping dimensions are 48" x 48" x 51".
I have an in-ground 20,000 gallon pool with 2" lines. Will this pump work with it and what is the shipping time?
Yes, this Heat Pump will work for that size pool. Please keep in mind it is best to also use a solar blanket to retain the heat that has been added to the pool. Lead time for any heat pump would be 5-6 business day's
Does this come with supplies to hook up the electrical?
Hello Joe, The Hayward Heat Pro Heat Pump 110,000 BTU comes with couplings to attach the heat pump to your plumbing, but it does not come with an electrical cable to connect to your breaker box. I would recommend you contract a licensed electrician to perform that part of the installation.
Can I use this unit with 1 1/2" lines Thanks
Yes you can use 1.5 inch lines as long as the max horse power on your pump is no more than 1.5.
Will this unit also cool my pool?
Hello Katie, This unit will NOT heat and cool your pool. Here is a link to the Jandy Pro Series Heat Pump 137,000 BTU Heat/Chill that would fulfill your request.
Hello, If I purchase a Hayward Pro heat pump from you and have it installed by a registered plumber will the warranty be valid should I have any problems with the unit?
Hello Don, We always recommend equipment installations are performed by licensed electrician and pool equipment installers. Should you have any questions on Hayward's warranty coverage, feel free to contact them directly at 1-908-355-7995.
I have The Hayward Heat Pro Heat Pump 110,000 BTU (HP21104T) for a 13,000 gallon pool. Can I install the Heat Pump on a 15 deg. angle? My slab has a slope to it.

What is the normal decibel level when this unit is running. I have a neighbor that likes to complain about noise.
Hi John, Hayward does not list the exact decibel of these units, but the HeatPro-Brochure implies that these units are under 60 dB.
I have a Hayward Heatpro HP21004T about five years old. The metal connector from the compressor to the condenser has corroded and linked out all the refrigerant. Would this be covered under the compressor warranty?
Hi Terry, Unfortunately we're unable to answer your question. You will have to contact Hayward at 908.351.5400 to find out.
My old heat pump has a bypass valve between water in and water out on the out side of the unit . Should I reuse it or is it necessary ?.
I would reuse the valve for the times you're not using the heat pump and needing that extra flow rate.
My pool is a volleyball pool 14'x28' it is 5.5' in the middle and slopes to 3' at either end. is this the correct unit, amount of BTU we should be looking for our in ground pool?
Hi Timothy, This unit can be used to heat your pool, however I Would recommend the HP21254T.
What is the footprint size of this unit
Hi Rod, This unit has a footprint of 31-1/4" DIA x 40" H.
I have a 18x36 oval shaped in-ground pool approximately 8' deep end and 4'shallow end. What heat pump would be the right fit for me. I would like to maintain 85 degrees. Plumbing and pump system is located 10' to pool. I live in MA.
How well do heat pumps work in southern California. Currently its 75 degrees with 47 percent humidity. Could a heat pump bring my 18,000 gallon pool up to 82 degrees?
The Hayward HP21004T would be a good fit for your location and pool size.The Temperature Set point: Pool and spa mode range is 50-104°F (21-40°C). (As listed in the Hayward Owners Manual pg.12 of 22 for the HP21104T) Please click here to view the Owners Manual for the Hayward HeatPro.
I have a 21ft round above ground pool.I have a 220v line already run with a 40 amp circuit. Will I be able to use 50btu pump or the 110 btu pump is only option? I live in central NJ.
Steve, Based on the pool size, I would recommend the 95k BTU Hayward Heat Pro. Please note that the heat pump needs adequate ambient temperature and humidity to operate correctly.
Is this heat pump and the 125, 000 and 140,000 heat pumps the same loudness. I would have to install it close to a lanai along with my other pool pump. I am wondering if the noise is going to be too much.?
I spoke to the technicians at Hayward ( 908-355-7995 ) and was told there is no difference is sound level between the 110,000, 125,000 or the 140,000 BTUs. As for how loud it will be, he could not say since it depends on the size of the pump, the plumbing size and any other obstacles the water may encounter on its way to the the heat pump.
I'm a pool technician and I have a customer with a heat pro heat pump. We normally service Jandy equipment and my resources are limited with this heater. The heat pump will not cut on and the a/c code is flashing on the display. The control pad is not responsive and power was cut several times to reset. In coming power is OK and transformer voltage is 28v. Any other ideas? Ambient temp today was 57 degrees F.
Hello Jim, the Outside temperature too low. Low ambient air temperature will cause the unit to not work properly. The outside air temperature to exceed below 60ºF.
what size pool heater fo 18x36 pool
Hello Don, this is going to be a good size for this size pool. We also would recommend purchasing a solar cover to maintain the heat that has been added to the pool. PART#SC-BS-000044
My neighbor has this and the water pump is humming so loud I can't sleep as its close to my bedroom. What can I cover it with and does it have to stay on 24/7...thank you 4 your reply
Hello, with Heat Pumps you can not cover them with any cover or walls. They are like AC units and have a set requirement for clearance.

what is the warranty on your heat pumps
Tom- The Manufacture's Warranty on the Hayward Heat Pro Heat Pump 110,000 BTU HP21104T is as follows :2 Year Warranty on manufacture defects,5 Year Warranty on Compressor,10 Year Warrant on Titanium Tube.
JUST INSTALLED NEW HAYWARD POOL MODEL HP21104T IS FLASHING CODE P-5 WHAT IS THE CAUSE. HOW DO I FIX IT
This code means that the pressure switch itself is bad or the water flow is low. Start with cleaning and or removing the filter then testing to see if after that the flow increases. Also make sure that there are no turned valves bypassing flow through the unit. There could be a number of reasons that water flow decreases but start there and if that does not solve it, move to testing potential pump issues.
How does air temp affect the heater performance? If it is 30 degrees outside will I be able to heat my pool to a comfortable temperature?
Anthony - Here is a heat pump calculator by Raypak that show you the impact of severals factors on a heat pumps performance including outside temperature: Raypak Heat Pump Calculator. Select a comparable Raypak Heat Pump at the top: 5350ti = 95K BTUs; 6350ti =117K; 8350ti = 133K. Fill in your local parameters and click "Recalculate". Change the parameters to see their impact on the heat pump's performance.
Does this unit require a GFi breaker when installing?

Can I use this heat pump in a salt water pool? If so any specific cleaning necessary ? Thanks.
Kar, Yes the heat pump can be used with a salt water pool. It is highly recommended that a check valve and bypass are installed. It is also recommended that the outside of the unit be sprayed down periodically if it is near the pool.
installing a chlorinator after the heater. What kind of check valve or backflow preventer should be used?
Yes you should install the chlotinator after the equiment and yes a back flow should be used. PART#25830-400-000
I have a Hayward Heat Pro (110,000 BTU) and 19,500 gallon pool. I have not been able to get the pool above 85 degrees and the outside temperature has been in the low 80's. Does the outside temperature need to be higher for the hear pump to raise the pool temperature?
Hello Bill, Yes Ambient temperature and humidity play a factor in the BTU Heating Performance. Attached is a link explaining BTU HEATING PERFORMANCE
what size heater should be a good for 24 ft round pool and I am in the north east?
Sumit - A 110,000 BTU would be adequate for your size pool. Of course anything larger would heat your pool that much faster.
will this heat my 18x40 pool 28,080 gallons, are there heaterS with remote access from my ipad
Stan, This Hayward Heat Pro Heat Pump 110,000 BTU can heat your pool. Depending on how fast you would like it heated, you can go with a larger size BTU unit. Heater Pumps by themselves does not have the capability to be accessed remotely, you will need to have to the heat connected to an Pro Logic Automation Controller that has the capability to be access from your iPad.
1. Is this the proper size heat pump for the following size pool: 14x17x28 mountain lake inground, 3.5 to 6.5 deep. 85 degrees desired temp. Centra PA 5/15 - 9/15. 2. Can this be run on an 30AMP circuit?
Hello Rich, This heater requires a 60 amp breaker. For your size pool I would go no smaller then a 110BTU and maybe consider looking at the HP21404T
I have a pool that is 13X24 (4' - 6' deep) with a 6X8 (3' deep) Spa attached. Will the Hayward 110,000 be the right size for me?
Jim, This Hayward 110,000 BTU Heat Pro Heat Pump will be good for your size pool.
What happening when it flash's LP? Model HP21002.
When the heat pump flashes "LP" when the low pressure switch detects that the refrigerant pressure is low.
What size heat pump in BTU's do I need to heat 14,000 gallons to about 85 degrees?
This Hayward Heat Pro Heat Pump 110,000 BTU will heat your pool however the higher the BTU's the faster it will heat your pool. You can go with the Hayward HeatPro Heat Pump 125,000 BTU or Hayward Heat Pro Heat Pump 140,000 BTU for faster heating.
Hi. I need to replace an older H-Series Millivolt 250 Propane. I live in TN. Pool size 32 X 15. Would the the Heat Pro be a recommendation for this area and pool size? Also considering a newer H-Series 250. Thanks in advance.
Hi Brian, Yes the 110,000 BTU Heat Pro would be adequate for you size pool. The benefit to the heat pump will be that it will cost much less to heat your pool over a gas heater. The downside to the heat pump is that it takes a little longer to heat the pool water over gas and once the outside temp. drops below 50 degrees they are inefficient. I actually have a heat pump and a gas heater on my pool and 99% of the time I use the heat pump and not the gas heater, so a heat pump would be my recommendation.
In the HP 21104T heater, i'm installing it in a area against the brick face of my home. To be specific in an enclosed fence with plenty of air space, no direct sunlight. Any suggestions, is this the right heater to fit my needs. Pool holds 10,000 gallons .
Hi Crissy, You will definitely want to make sure you have proper ventilation on all sides of the heat pump. Proper ventilation for this model is 24" of clearance on all sides of the heater. This heat pump would be great for a 10,000 gallon pool.
Hi, does this unit includes wiring/connectivity for remote operation and will it be compatible with Jandy iAqualink system for remote operation? Thanks
Alex, This unit does not come with any wires for electrical or for connectivity for remote operation. You will have to contact Hayward Tech Support at (908) 355-7995 or Jandy at (800) 822-7933 to find out if this unit is compatible with your automation system.
Can the pool pump and filter run without running the heater.
Frank, Yes it can. You can have the heat pump off and still run your pool pump. If you don't have an external bypass to the heat pump the water will still flow through the unit but not heat the water.
I'm installing a new electrical line for this Hp21104T heater What's the voltage, amperage and phase for this unit
Sal, You'll need a dedicated maximum fuse size of 60 Amps, minimum 35 amps, 240 Volts, 60 Hertz, 1 Phase to operated this unit.
If I install will it be warranted If service becomes necessary who will service Eatonton Ga
Gregg, In order for this heater to maintain its warranty it would need to be installed by a licensed and ensured company with receipts of install. If service becomes necessary you would contact the manufacture.
What type of pool cover is needed that's easy enough to take on and off every day to maintain pool temperature?
Sal, A solar blanket with a reel will be what you will need to easily cover and uncover your pool to maintain the pool temperature. The solar blanket is based on your pool size.
Can I install this unit next to an outside air conditioner compressor unit. Will this affect any of the efficiency of the unit or what it actually improve the efficiency due to the fact that the AC compressor unit blows out hot air.
Enoc, A minimum of 2 feet (.6 m) of clearance from walls, shrubbery, equipment, etc. is required around the entire heat pump. This allows for ample air intake. A minimum of 6 feet (2 m) of clearance above the heat pump is required to prevent re-circulation of air. I would consult a licence HVAC contractor about how the units efficiency is affected by each other.
Is the Hayward HP21104T big enough or to big for a 13' x 25' 5'6" deep end?
Hi David, Yes this Hayward heater (HP21104T) will be sufficient enough for a pool your size.
Unit is flashing "P5". What does this mean?
The heat pump is actually displayng "PS" which stands for pressure switch. Either there is not enough water flow or the switch is bad. Bypass the filter to possibly increase the flow and test. If it is resolved then it is a filter issue. If not then it is the switch itself.
How well does the heat pump stand up to the chlorine in the water? As a heat pump, is it required to bury piping in the ground to transfer heat?
Don, The heat pump will be able to withstand recommended chlorine levels (1-3 ppm). You will also want to monitor pH, alkalinity and calcium hardness as those levels can corrode the "guts" of the heat pump. The plumbing does not need to be buried as a majority of your pool plumbing is already buried.
What is the weight of this pump? Thanks
The weight for this heat pump is 240 pounds.
Can the heat pump be turned on and left on with a pool pump that is switched off at night with a timer? Will the heat pump sense the no flow and take care of itself? Is this an acceptable way to operate the heat pump?
Yes you can install it that way, The heat pump has a sitch that will turn off the heat pump if there is not enough water flow. If you have any further questions please feel free to reply to this email. In addition, you may view the entire ticket history or enter a response by visiting the link below.
Can I install this heat pump indoors?
Unfortuantely Hayward does not recommend installing the heat pump indoors.
I am replacing a Hayward HP21002, are the fittings for inflow and outflow the same size and same location on the HP21104T or will plumbing need modification?
The plumbing would be the same size and the ports are few inches off from the old location so there would be some slight plumbing modification
Is the refrigerant in Hayward heat pumps environmentally safe?
Yes. Hayward uses R-410A refrigerant in all their heat pumps.
Can a heat pump be installed under a deck?
No. Any installation that causes the air being discharged from the top of the heat pump to be recirculated back into the heat pump will cause a loss of capacity and efficiency in the heat pump. Installation of a heat pump under a deck, or a low over hang will allow the air being discharged to be drawn back in by the heat pump.
Can a heat pump be installed indoors?
Generally no. Heat Pumps work by transferring heat from the surrounding air to the pool water. If a heat pump is installed indoors there must be a continuous supply of warm air from which the heat pump can extract heat. If you must heat the air in the room before the heat pump can extract that heat to heat the pool, there would be no benefit to the heat pump.
If I have a large pool pump will I need to have a flow meter for the heat pump?
According to Hayward their heat pumps have a flow rate range of 30 to 70 GPM, with an optimum flow rate of 45 GPM. If your pump is capable of significantly more flow than this, a flow meter is recommended to insure the flow rate is within the prescribed range.
Is the Hayward HP21104T the replacement for the HP21003T?
Yes, the Hayward HP21104T is the replacement for the HP21003T.
Is the Hayward HP21104T a replacement for the HP21002?
Yes, the Hayward HP21002 has been replaced by the HP21104T.
Is this the replacement for the Hayward HP2100TCOT2?
Yes this is the proper replacement for the HP2100TCOT2.
Would this be the proper replacement for the Hayward HP2100TCO2?
Yes this heat pump is the suitable replacement for the Hayward HP2100TCO2 heat pump.
This heat pump is labeled for an in-ground pool. Can it also be used for an above ground pool?
Yes, this heat pump can be used with an above ground pool. You just have to ensure that it is wired correctly. It needs a 60 amp dedicated circuit breaker and has to be wired directly to the circuit breaker box.
2 to 4 hrs
Screwdriver, Pliers, Adjustable Wrench, Hacksaw, wire stripper, dolly to move heat pump.
1. Went to Inyos Pool website, and found replacement Hayward Pro Heat Pump 110,000 BTU. Ordered, and delivered.
2. Watched YouTube video on how to hook up heat pump.
3. Took pictures of plumbing and electrical of existing heat pump, in place.
4. Disconnected (turned off) circuit breaker for heat pump. Opened GoldlinevController cover panel and disconnected heater control wiring from Goldline controller panel.
5. Disconnected PVC 2 1/2” inlet and outlet pipes by cutting (as close as possible to heat pump flanges).
6. Disconnected electric wires from circuit breaker box (opened up breaker box, took inside picture, disconnected and labeled each wire). Then had to disconnect wiring from the heat pump (but did not yet reconnect wire to circuit breaker box). Took picture before disconnect.
7. Disconnected Goldline Controller connecting wire from old heat pump.
8. Removed heat pump from concrete pad.
9. Moved new heat pump to concrete pad, about 3” to 4” closer to cut piping, to connect to cut pipes. New replacement heat pump was same model (newer version) so pipes lined up perfectly.
10. Inserted pipes into inlet and outlet flanges. This was a bit difficult, as I originally put in a bypass pipe and valve between inlet and outlet, so the inlet and outlet pipes were pretty rigid, but since they were aligned to flanges, was able to get them inserted. Used PVC glue on interior of flanges and circumference of pipes before inserting.
11. Connected heat pump wiring to bottom of heat pump electrical, using previous picture as guide.
12. Connected other end of electrical to opened circuit breaker.
13 Closed circuit breaker cover.
14. Connected control wiring to Goldline Controller, and to new heat pump.
15. Turned on circuit breaker.
16. New Hayward Heat Pump LED screen lit up.
17. Set temperature to 85F.
18. Heat pump began operating.
19. Hayward Controller settings for heat pump were not changed from prior (old heat pump) settings.
20. In hindsight, realized I only needed to disconnect electric and controller wires at the heat pump, not the circuit breaker and Goldline Controller.
Now I want to see if I can buy a replacement heat exchanger for the old heat pump, as the compressor motor and everything seemed to be working.
4 to 8 hrs
Installation - leveled the ground, laid some concrete pavers, set the heat pump, plumbed it and wired it. Everything was great except two noticeable things. One was that I installed the heat pump lower than the pool surface and the manual mentioned I might need to adjust the pressure switch, however, it appears they changed the design and it didn't match the picture in he manual. It turned out it wasn't an issue at all. The other was that I would have figured there to be a more secure wire connection. Usually when making an electrical connection there is a connector to hold the wire securely to the unit. In my case there wasn't one. Not an issue for me - there were two holes and the one they wanted me to use (as indicated by location and some type of fitting) was hindered by "stuff" below it so I used the other hole and added my own secure connector. Also, the lugs are not sized for wire size 6AWG, but that just happened to be the wire I had available and you can get by with wire size 8AWG so it isn't an issue. I posted 4-8 hours of time, but it depends on how much prep you need to do. The actual installation was ~2hours, but I had a few more hours into it to prep the location and pull wire from the house and fit the PVC piping so that adds to my time that may not be the case for somebody else.
1 to 2 hrs
Screwdriver, Nut Drivers, Pvc accessories and connectors
We purchased this heat pump after reading all the reviews on at least 8 others. This was the best one and inyo had the best price by almost$400. Ordering and shipping went flawless. After making a concrete brick platform for it, my buddy helped me install it. By far the best thin ng I did for my pool.

I bought this heat pump, Hayward Heat Pro Heat Pump 110,000 BTU, and saved a lot. It was delivered within a few days. The pump is working like a charm, my pool is now useable all year. In winter I set it to 85F and everyone in the family loves it.
(5 out of 5 stars) Great pool heater!

Pros: pleasant swimming condition, runs quietly and efficiently
Cons: price of purchase and installation
For years I have been tempted to buy a heater so I can enjoy my pool more by taking the chill off the water. I assumed it would be a very expensive proposition. Much to my delight, this heater works very well and my electric bills have shown much less of a bump then I expected. By covering the pool in the evening, it loses only a few degrees at night and quickly reheats just by sunlight. I have it set to go on if the water temp goes below 81 and it has not run once the entire month of July. I enjoy going into the pool in the evening, floating and chatting without feeling chilled by cool water. The grandkids love, love, love the warm water and swim for hours! We could not be more pleased with this product!
(5 out of 5 stars) No issues - works great so far
Reviewed By: ()
Just installed it a few days ago and so far so good. Easy to install. I happened to use 6AWG wiring and the lugs are too small for that, but most would likely use 8AWG I believe so not an issue. You may want to use a secure connector when entering the panel since there wasn't one. The PVC connection was very easy. My connections were not entirely square, but they didn't leak and the unions were only hand tightened so that's good. It said to push the POOL button, which I did, and set the temperature. In my case, I have a two-stage pump and the low stage doesn't provide enough flow so the low water pressure interlock prevented it from starting as indicated by the panel display flashing me a "PS" (for pressure switch - manual says it means low water pressure) . I turned my pump on high and it worked fine. My water temperature started at 69F and it was actually a bit cooler outside (manual says heater works best if in the sun, but that wasn't an option for me so it is shaded). I had calculated about 1.5 hours (at 100% efficiency) to heat my ~15,000 gallons one degree Fahrenheit, but it took more like 2-3 hours (I'm not complaining). That's a rough figure since I wasn't watching it closely. I'm not sure how much heat loss I have, but do have a 24' diam round aboveground pool.
