If I have a large pool pump will I need to have a flow meter for the heat pump?
 Reply

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

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.

Can a heat pump be installed indoors?
 Reply

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

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.

Can a heat pump be installed under a deck?
 Reply

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

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.

Hello Jerry, I would never suggest putting any form of chlorine into your skimmer. Doing so will damage your pump, filter, and heater. The purpose of the check valve between the chlorinator and the heat pump is to prevent concentrated amounts of chlorine from entering the heat exchanger. By putting chlorine into the skimmer would send the very highly chlorinated water through your filtration system.

We just purchased from you and installed a Hayward Heatpump Pro 140,000 BTU heat pump. Hell of a great unit. Took our above ground 20x40 pool from 55 to 80 in a couple of days. Love it. Question is this. Our pump is manually turned on and off with no timer as of now. How do we shut off the Heat pump when the pump is off. Right now I am turning off the circuit breaker for the heat pump. My question is do I have to do that or can I just shut off the pool pump and let the heat pump turn itself off.
 Reply

A  Answered on 5/29/2016 by InyoPools Product Specialist Alex V.

Jerry, Good to hear you are happy with your purchase.  The heat pump has an internal flow sensor. The heat pump should not come on if there is no water flow. You can test this next time you turn the pump off. The only downside is that if the sensor fails for any reason, the heat pump may try to run.

The pipe connections are located on the rear of the unit near the base. To connect the electricity, you must unscrew the five screws of the front panel, then slide the electric cable through the knockout located on the left or the right side of the base, and then insert it in the control box.

Hi, Tony. No, you do not need a check valve between the pool and the chlorinator. If you have a heater, it would not be a bad idea to place a check valve between the heater and the chlorinator to prevent backflow of concentrated chlorinated water into the heater piping.

If you are wanting to heat your pool quick a heater, either propane or natural gas, would be the way to go. A heat pump will get it to the temperature that you want it to be, but not as fast as a heater. You would heat your pool efficiently with a 200k or 250k BTU model heater.

Good afternoon Bill, The Hayward Heat Pro Heat Pump 140,000 BTU - HP21404t would be a great heat pump for you.  You can figure about 5,000 watts or 5 kilowatts per hour per 100,000 BTU’s for a heat pump. For a typical 100,000 BTU heat pump, that’s 5 kilowatts per hour. The national average for Electricity runs $.13 cents per kilowatt hour. Electricity costs vary widely throughout the United States so checkout this website updating the Electricity Costs for all 50 States. In our example, 1 hour on a heat pump will cost .60 cents.

Hi Lisa, Yes this would be the Heat Pump we suggest for a 33,000 gallon pool. Please note that heat pumps do take longer to heat a pool than a gas heater but they cost a fraction of the price to operate, so you can run the heat pump longer without spending a ton of money on operational costs.

 Reply

A  Answered on 4/25/2017 by InyoPools Product Specialist Scott W.

It will depend on the weather everyday, but the heat pump is set up to turn on whenever the water temperature goes below what you set your desired temperature and runs until it is back to that temperature, and will run as long as your pool pump is on.

I have a pool around 22,000 gallons, about 490 ft2. I live in central CA & would like to heat the water 15 degrees over ambient temp 3-4 months of the year. If it's 70 degrees outside, for example, I'd like to get the pool water to 85 degrees. How much electricity (kwH) would you estimate one of your heat pumps to use for that on a monthly basis? I was looking at a 140,000 BTU unit. Would that size be correct? Thanks.
 Reply

A  Answered on 4/26/2017 by InyoPools Product Specialist Scott W.

You would be looking at about $110-160 a month. It will be on the higher end initially because it will have to go from 70 to 85 degrees but once it is there all it has to do is regulate your water temperature and will go toward to lower end for cost.

Hi Tina, no the heat pump does need to be outside as the heat pump draws in the outside air to heat the water. When the heat pump is heating it actually outputs cold air and if the heat pump is inside then the air in the room gets cold and then the heat pump has a hard time heating.

Hi, Mario. I would recommend installing a manual bypass that way if your flow rate exceeds 75GPM you can regulate it and also shut off the flow to the unit when it's not being used.

HI, Tyler. A Manual Bypass is necessary for these top two reasons. If the flow rate of the pump exceeds the maximum flow rate of the unit and to cut off water to the unit when not in use. Yes, you can leave the valves open running water through the unit when it's not in use.

Hello Rob this unit must be installed to it's own 42-60 amp dedicated breaker. This heat pump must be connected to a bonding grid with a solid copper conductor wire gauge 8 AWG or larger to comply with Article 680 of the NEC. All Hayward heat pumps are designed for copper conductors only. The National Electrical Code (NEC) in Article 680, and most other codes require that all metallic components of a pool structure, including reinforcing steel, metal fittings and above ground equipment, be bonded together with a solid copper conductor wire gauge 8 AWG or larger. The heat pump, along with pumps and other pool equipment must be connected to this bonding grid. A bonding lug is provided on the rear of the base pan of the heat pump to facilitate bonding.

 Reply

A  Answered on 4/5/2018 by InyoPools Product Specialist Joe S.

Automatic erosion type chlorinators, if used, must be installed downstream (between the heat pump and the pool) of the heat pump, and a check valve (or Hartford Loop) installed in a manner that will not allow the raw chlorine to drain back to the heat pump when the water pump is off. Failure to follow the instructions may result in property damage.The heat pump is designed for a maximum flow rate of 75 GPM. An External Bypass Assembly can be added to regulate the flow rate through the heat exchanger to prevent damage. Failure to install an External Bypass Assembly with a flow rate of 75 GPM or higher will void the warranty.

Hello Lorenzo- Unfortunately these heaters, as you know, require a minimum flow rate to operate. You would need to either find a variable speed pump that you can program such as the PureLine Prime Variable Speed Pool Pump 1.65 HP - PL2605, or only heat the pool when necessary and on high speed. By getting the VS pump you would be able to find the lowest possible RPM to run the heater instead of being stuck with just High Speed as an option.

We have a hot solar water heater currently. Heat is transferred via a heat exchanger. We are thinking of upgrading the heat exchanger and was wondering if installing this type of heat pump would be beneficial. If there's no sun or no hot water produced by the solar system, the heat pump would provide the heat transfer. If solar is active, then pre-heated water would be passed through the heat pump without requiring any additional heat. Is this a feasible use case?

Economically, does it make sense to turn the heater off for 10 cool days and then bring it back up to 83. Does it make more sense to leave it on..

Pool is approx 16x32 w/approx16-19000 gallons (every person out here measuring says something different). Would the 125K be efficient? There's a differece of opinions depending what dealer I speak with. We're being told the 140K wouldn't make a big enough difference in heating for the extra money spent, & others highly disagree. We are in Central FL near the coast & wish to keep the pool around 80-85 as it will be used for fun, but also therapeutic purposes.

The formula I use is… surface area of pool x temp rise x 12= btu req to heat. (800 x _____x 12 = BTU to heat) The temp rise is the difference between average coldest temp where you live and what they want for a water temp.

We have purchased a home in Port Charlotte, FL where the old pool heat pump needs replacing. It is a small pool of only 2000 gal. Is a heat pump the best option, and if so what size would you recommend. Thanks
 Reply

A  Answered on 10/15/2019 by InyoPools Product Specialist Steve M.

Glenn, for your 2000 gallon pool we would not suggest such a large heat pump. I would suggest something like the E3T Electric Digital 18kW Pool/Spa Heater - 017123.

I am interested in buying a heat pump for my pool. Does the Hayward model have a way of turning on the pool filter pump? Does the heat pump turn on when the pool pump timer turns the filter on, or do you have to turn on the heat pump daily?
 Reply

A  Answered on 8/22/2019 by InyoPools Product Specialist Joe S.

Good day, this unit does not have an option to turn on a pump. We would recommend the Raypak Classic Series Heat Pump 140,000 BTU - 016033. Either unit will turn on when there is water flowing through the unit and it will need to achieve the desired temperature.

Does this tie into the existing filtration system. If not will this work with 250 GPM ?
 Reply

A  Answered on 8/25/2019 by InyoPools Product Specialist Lennox H.

Hi. Yes, this is plumbed after the filter of the circulation system. This unit is unable to handle a flow rate of 250 GPM. It can handle a max flow rate of 75 GPM. A manual bypass will need to be install.

I have a customer who purchased a pool heat pump 1 year ago. He is now losing Freon. Since this is a closed system, what could be the cause of the Freon loss? When he purchased the new heat pump, he also converted over to a salt water pool. Could his salt level have anything to do with the damage to his coil? Are your heat pump coils made of aluminum or copper?
 Reply

A  Answered on 10/22/2019 by InyoPools Product Specialist Lennox H.

Hi, Jody. A leak in the freon line is the issue. This can be caused by several factors including corrosion from a saltwater environment. The unit will have to check out by a qualified technician. You can reach out to Hayward since the unit is within the warranty period.

Hello, I am planning to purchase this heat pump and I have three questions: 1. what type of electrical wire do your recommend, knowing that the distance between the pump and my electrical panel is about 100 feet, 2. what type of valve do you recommend I use between the heat pump and my chlorinator, 3. I use 1.5 inch PVC pipe with my vario-pump but it looks like the in and out pipe or much larger. Is that a problem? Thank you!
 Reply

A  Answered on 3/23/2020 by InyoPools Product Specialist Lennox H.

Hi, Anthony. Using a 60 amp breaker an 8 AWG wire is recommended. The Clear Check Valve 1/2 lb. w/ Unions - 1700C20 (2") or 1700C15 (1-1/2") is our preferred option. Using 1-1/2" plumbing is not an issue.

A cable is not included with the W3HP21404T heat pump. The heat pump should be hard-wired 240v to a 60 amp breaker. The gauge of the wire would depend on the distance to the breaker, but we recommend consulting an electrician to confirm.

Hello Christopher.  The Hayward HeatPro 140,000 BTU Heat Pump would be an excellent choice for a 30,000-gallon pool.  The 140K BTU would deliver a quicker heat rise than heat pumps with a smaller BTU rating given the same pool water temperature, air temperature, and humidity conditions.

I installed this heat pump recently on a 32,000 gallons pool with a Pentair VS pump running at 2600 rpm, a Quad DE 100 Filter with a multiport valve. Filter is backwashed and showing pressure at 15 psi. However, I keep getting FLO error on the heat pump in FILTER mode. I know there is good water flow as the salt generator connected downstream from the heat pump works fine. Interestingly, the FLO error disappears if I switch to recirculate mode on the multiport valve. Any ideas on the issue?
 Reply

A  Answered on 6/12/2021 by InyoPools Product Specialist Danny R.

My guess (This one is hard to tell without being there) is there really is not enough flow getting to your heat pump.  So I am guessing it is more a problem with your multiport valve.  Maybe it's not turning all the way to get proper flow to the heater.
 Reply

  • Commented on 6/12/2021 by Product Owner

    Thank you. It is an interesting viewpoint. Multiport valve is less than a year old. Would it fail so quickly? If there is an issue with the multiport valve, would the salt generator also not show a flow error? I would appreciate if you can share any ideas on testing and isolating a multiport valve problem. Thank you.
     Reply

    • Commented on 6/14/2021 by InyoPools Product Specialist Danny R.

      Again I am just throwing out ideas here.  So although the salt generator is showing it is getting enough water flow it might not be enough for the pool heater.  I would check to see if the multiport valve is opened all the way while in the position that sends it to your heater (or when you are having the issue).  It might be that it is not completely turning to allow the full flow to come out.  The other thought is maybe there is a clog somehow in the valve.  Of course it could be an issue with your heater, but if you are able to get proper flow through your heater when the valve is in a different position it points to it not being a problem with your heater, but rather an dissue with your plumbing.  It's either the way it is set up or a problem with one of the valves.

This unit will operate fine at hot outdoor temperatures, but the BTU output does drop as the ambient temperature and humidity drops.  The brochure for the heater does not have information on 60 degree ambient air, but you can expect to only get 85,000 BTUs when the exterior temperature is 50 degrees.  See the sales brochure for more complete information on the performance of the heater in different conditions and be sure to view our guide on Sizing Your Pool Heater and How to Select an Inground Pool Heater to be sure you get a heater with the performance you need for the size of your pool.
