Hi, Currently we have a Pentair ThermoFlo HP900 heat pump that needs to be replaced with the input and output flow on one side of the unit. The new Ultra Temp 120 has the flow on either end of the unit and would present a plumbing issue. Can you tell me the distance between the input and output on the Hayward Unit? If we install the Hayward will it connect with our Pentair Easy Touch control system? I've added a picture of our current set up so you can see the plumbing issues. Thx!

 Reply

A  Answered on 5/6/2019 by Industry Professional

Hi, Chase. The distance between this Heat Pump connections is 18-7/8" center to center. This can hook up to your control but since it is not a Pentair Heat Pump it would limit the controls to basic On/Off.

A  Answered on 4/13/2019 by InyoPools Product Specialist Lennox H.

Hi, Bob. It's possible, It all depends on how your system is plumbed and the temperature of the water exiting the panels into the heat pump.

We have a DEAD HP21003T pump that we are looking to replace with Hayward HeatPro Heat Pump 125,000 BTU's - HP21254T. The dead one is currently sitting on a 36x48 pad. Will it be an "easy" switch out or require a larger pad, higher circuit, different piping or anything else? I want to sound like I know what I need when I call around for installation :-) If possible, will you let me know via email either the answer or when it is posted on this site. Thank you so much!
 Reply

A  Answered on 2/5/2019 by InyoPools Product Specialist Patrick P.

Hi Claudia, There will be some re-plumbing but the hard part of adding the appropriate electrical will not be needed as that will already be in place from your current heat pump. We recently made a Video on How to Replace a Hayward Pool Heat Pump and this will be almost identical to the job you will have performed. I would suggest watching that video and you can see that it should be a relatively easy job.

?     Asked on 11/29/2018 by Jihua Peng

Does it work when outside is cold?below 50 degree
 Reply

A  Answered on 11/29/2018 by InyoPools Product Specialist Jamie H.

Hi Jihua, Low Ambient Temperature If the air outside the heat pump is not warm enough to produce heat, the system will shut down. The actual point at which your unit will shut down due to low temperature varies depending on which model you purchased, current weather conditions, and the amount of sunlight reaching the heat pump. The shutdown can occur anywhere within a wide range of temperatures, usually 45≡F-55≡F. This is not a “fixed” range. We stress that climate conditions, sunlight, and various models respond quite differently to low ambient temperature. A shutdown occurs because low temperatures will activate the systems low-pressure safeguard switch (digital thermostats will display a code “LP”.) The unit will start up again when the temperature has raised enough to reset this switch. Note: Low ambient temperature does not necessarily affect the Chiller models or the cooling cycle of the heat/cool units.

How does the heat pump run in unison with the pool pump? are they both controlled with a timer so that they run at the same time? i have the hp21254T purchased from you and when reading the electrical schematic it does not mention the timer. if i turn the unit on and off using a timer does it automatically come on and use my previously set or does it need line voltage and to be turned on and off via controls?

I live in central NJ. We like to swim from early May through early September. I use no cover with my 16 x 32 inground pool. My Hayward heat pump is 20 years old and it is showing a Code to call for service. I think it may have seen its last good day. My question is, I bought this heater for my old 20x40 pool and brought it with me when I moved. What size would I need to keep the water around the 85* temp?

I would not recommend a heat pump smaller than the 125,000 BTU model that you currently have. A heat pump with less than 120,000 BTU is going to go inefficient.

I know California is very focused on conservation and reduction of energy usage, as well. The 125,000 BUT unit would be sufficient, but keep in mind that it would require longer periods of run time to reach your desired temperature.

Yes, you would need a 60 amp breaker for that heater and the plumbing is 2" but that will not be a problem. You will just need an adapter when it is installed. The minimum flow rate is 30 gallons per minute on that heat pump so if your 3/4HP pump is pushing that then you will be fine there. As far as the bypass valve, that would be a yes. Anytime you are not using your heat pump you would want to use the bypass valve to help prolong the life of your heat pump.

I am interested in this or the 140 BTU version. My inground pool is 16' x 29' and 5' 10" deep. I am interested in warming it up fast and best savings on energy. I live in WV, so I want to extend my pool season longer. Which one would you recommend? Thanks

A  Answered on 6/25/2016 by InyoPools Product Specialist Lennox H.

Hi Roy, I would recommend the Heat Pro 140,000 BTU (HP21404T) unit, it will heat the pool faster.

We just purchased the HP 21254T. I see the inlet and outlet are 2 inch in size. My filter and pump are all plumbed with 1.5 inch piping.Can I reduce the inlet and outlet on the heater or should I try to replumb everything else to 2 inch?
 Reply

A  Answered on 5/30/2016 by InyoPools Product Specialist Alex V.

Tim, Yes you can reduce it to 1.5" if needed.

does this have to be in direct sun light to work best.
 Reply

A  Answered on 4/22/2016 by InyoPools Product Specialist Alan M.

Hello Michael, This unit does not require direct sunlight to heat the pool. The heat pump takes the heat from the surrounding air and uses it to heat the water in your pool.

Hello Wayne, The Hayward HeatPro Heat Pump 125,000 BTU does not come with any electrical plug. You will need to consult a licensed electrician in order to connect the heat pump to its own dedicated breaker.

I live in a community in Florida that does not have gas lines. Do these heat pumps work on electric? If so how, what does the btu refer to on these units?
 Reply

A  Answered on 3/24/2016 by InyoPools Product Specialist Lennox H.

Hi Chris, Heat pump uses electricity to operate. BTU is the measuring unit used to raise the temperature of one pound of water by one degree Fahrenheit. The larger the BTU the faster it will heat.

What is the difference between this and the HP21104T? other than 15Kbtu. The cost between the 2 is minimal. Is one better than the other? I have a 14X28 inground avg depth 4 ft (3 feet on each side and 5.5 in the middle).Great prices by the way!
 Reply

A  Answered on 3/10/2016 by InyoPools Product Specialist Lennox H.

HI Chris, That is the only difference between theses two models, is the BTU's. With the price difference being minimal I would recommend the HP21254T, it would heat your pool faster than the HP21104T unit.

Our pool is 28,000 gallons. Do you have a heat pump that will work with that size pool in central Florida?
 Reply

A  Answered on 2/22/2016 by InyoPools Product Specialist Hector F.

Being that your pool has a larger surface area it would be wise to go with any 140k BTU model. The Hayward Heatpro, Pentair Ultratemp and RayPak heat pumps are likely the top 3 most popular models.

 Reply

A  Answered on 2/16/2016 by InyoPools Product Specialist Joe S.

Hello Danny, yes the Hayward HeatPro Heat Pump 125,000 BTU's would be a good size for your pool. The manufacturer also recommends you adding a check valve such as PART#25830-714-000. With any Heat Pump or Heater we recommend you getting a solar blanket, to retain heat at night and on cloudy cool days.

A  Answered on 8/7/2015 by InyoPools Product Specialist Lennox H.

Hi Douglas, You can replace your HP21002 unit with the HP21254T model. The style of the units are different so you will have to re-plumb the replacement unit but the electrical will be the same. The only dimensions we have can be found on the Hayward Heat Pro Brochure.

Can you put hedges around it? Any danger to doing this after installed?

A  Answered on 5/9/2015 by InyoPools Product Specialist Joe S.

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. Canadian installations require a minimum of 120 in. [3 m] of clearance from pool water

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.

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.

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.
