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?...
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.
Hello David, The according to the Heat Pump Pro HP21104T Installation Guide, the heat pump should be installed on level ground (page 4). Feel free to reference the installation guide or contact the manufacturer directly if you have additional questions. Thank you!
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.

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.
Need the part number for the water pressure switch on a HP21104T
The part number for this water pressure switch is 6224-32.

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?
Installation Check: Verify the heat pump installation is compliant per this installation manual. Verify the electrical connection is correct by ensuring the breaker is sized correctly and the wiring is per the National Electric Code (NEC). Reference this installation manual to ensure that the plumbing is installed correctly.NOTICE: Service to be conducted ONLY by an EPA Certified Service Technician.
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?
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.

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!
Reviewed By: Pat B. from Annville, PA ()
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!
(4 out of 5 stars) Quality inground pool heatpump
Reviewed By: Urbigene from Central Virginia ()
Pros: Good Web site, fast delivery, quality product
Cons: On the expensive side.
Received the water heater less than a week after it was ordered. The heater was an in-kind replacement of the original heater which I had to replace because of wrong fully winterizing it. I installed by my self using new routing for PVC piping. Installation and putting it in service was easy. Unit started without any issues and I was able to heat up the 18000 gallons pool by 5deg F in about 5 hours.
(5 out of 5 stars) Hayward Heat Pro 110k
Reviewed By: Kevin H. from New Port Richey FL ()
Pros: Looks good, quiet, heats up well
Cons: None really
Delivery process and order process easy. Be aware though you will need help to move this unit. I managed by myself with a trolley and strap but it was heavy! Electrician wired from main panel to the other side of my home for $450. I plumbed in the heater and connected the power. Spent circa $100 on fittings etc. Very simple to operate and heats up my 9000 gallon pool in no time. Yet to see what impact is on my electric bill but use of s good quality solar cover will help.
(5 out of 5 stars) Easy quick installation
Reviewed By: Patrick G. from Fort Lauderdale, FL ()
Pros: Easy setup and connection, fairly quiet
Cons: Electrical hookup space limited
Ordered the pool heater and it got delivered yesterday 4pm. By 10pm I was done with installation, eg setting on the slab, making electrical connections and plumbing. Granted, everything was in place. The electrical hookup is very tight in space, they do have a coolant pipe right at the place where the conduit is supposed to go, but it works. The startup was without issues and the unit is fairly quiet. Comparable to a small air conditioner. I have a 15x30 pool, and starting temp was 70 degrees. We will see how long it will take to heat it up to 86.

Pros: New Technology
Cons: Apparently the new technology
This new technology heat pump seems to be slower at heating the pool than my old technology heat pump. The delivery was totally screwed up by UPS. INYO responded to the order quickly shipping the unit within 1 day but UPS sent it to Columbus, OH terminal and then sent it to South Holland, IL (near Chicago) instead of to me in Dayton, OH.

Pros: Heats well
Cons: Costly to run, but they all are.
We just installed our unit in the middle of the summer here in Ohio. I was very pleased that we got at least an extra month out of our pool at the end of the season by having this heating unit.
