If I have a large pool pump will I need to have a flow meter for the heat pump?
Reply
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
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.
Reply
Can a heat pump be installed under a deck?
Reply
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.

currently have a HP21002 116.000 Btu that needs replacing. Will the 125,000 btu HP21254 replace it ? What is the distance from mounting surface to bottom water connection and distance between water inlet and outlet.
Reply
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.

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.

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.

The best option would be the larger of the two. The higher the BTU's of the heater, the faster it will heat your pool. The faster the pool heats up, the less the heat pump will need to run, and that translates into energy savings to you.

Reply
Hello Dan- Although these two units are very similar, they are different in the BTU sizes. The larger the unit, the faster it will heat your water. The faster it heats the water, the less time it will need to run. This will translate into a reduced electric cost to heat your pool.

I have a few questions; why are the specs for the HP21254T not listed with the others, it goes from the 110 to the 140. What are they, I'm presuming it takes a 60amp fuse? next is I have 1 1/2 inch lines to and from the pool is this ok with the 125 unit? I'm in Florida, should I put a bypass in for the summer time. Lastly, I currently have a 3/4 hp pump should i go to a 1 hp? I'm lifting about 8' max. Thanks, you folks are helpful.
Reply
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.

Good morning Todd, Heat pumps are great for Central FL. Plus, will be way better on cost than a propane heater. I don't know about upper 90's. You would be running all the time to keep that heat.

Hello Kevin- I would recommend the Hayward Heat Pro Heat Pump 140,000 BTU - HP21404t based on the size of your pool.

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. You would need to upgrade the breaker to a 60 amp regardless of which unit you would choose.

We have a 39 x 18 in ground pool (26,000 gallons). We already have a gas line. Would this pump be a good fit? If not, can you recommend another? Thanks

I live in central Florida and have a inground pool approximately 10,000 gallons. I want to know the correct electric heat pump to purchase? HP21104T, HP21104T or HP21254T?

I live in Canada and was wondering when our desired heat is reached will the unit shut off and let the water flow through...or do we have to bypass heater?

how do you read the thermostat settings for temp?
has lines but no numbers, so just guessing when setting temp..

Hi, Stephen. The display on these units gives you a digital reading. If it's not, there might be an issue with the controller.

We live in southern Oregon, and have a 16x32 pool, 3.5ft shallow to 9ft deep end. Would like to be able to use the pool mid-April to mid-October, with 80-82 degree water temp. Will the HP21254T be a good choice? Thank you for your help!

SOMEHOW MY TEMPERATURE INDICATION IS NOW IN "CENTIGRADE" AS OPPOSED TO "FARHENHEIT". HOW TO I CHANGE IT BACK?
Reply
Hi, Charlie. Press the SET key until you see F_C and by pressing one of the arrow keys, you can switch to °F or °C. Once the temperature unit has been programmed, it will be displayed for five seconds, and will then return to the actual pool water temperature in the mode that you have chosen.

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? Thanks for your help
Reply
Hi, Josh. The heat pump does not need to be controlled by a timer. Once the unit is powered, its activated once sufficient water flow is detected.

I’m trying to decide between this 125k BTU unit and the HP21404t 140k BTU unit. The pool is only 8,000 gal and 270 sq ft. Surface area. I’m in NE Florida and worse case i would want to heat the water from 50 degrees to 80 or 85 degrees in the cold months. Will the 125k BTU unit suffice?

Hello Brian- The Hayward HeatPro Heat Pump 125,000 BTU's - HP21254T will work great for your pool and area.
Reply
Does it work when outside is cold?below 50 degree
Reply
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.

I think I have a 10,000 gallon pool. I want to replace the broken 110BTU heat pump currently installed. Would it heat the pool faster if I were to upgrade to a 125K or even a $140K BTU HeatPro?
Reply
Hello, Yes, if you were to upgrade to the larger unit. It will heat up the pool faster.

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
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.
Reply
Thank you. I did look at it in the hopes that maybe we could do it ourselves but just moving the bugger looks hard & heavy ;-) Also, will this one be able to be connected to my Aqua Pro remote?

I have an existing pool pump with a 240 line and looking to install a heat pump. Could this same line be used for the heat pump or would another line need to be run?

Can this heat pump work in conjunction with a pool solar system where the pool solar heats the water first then the heat pump bumps up the temperature thereat of the way to a preset temperature?
Reply
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.

will this work on a 28ft round above ground pool

Hi. This unit will heat a 28' round above ground pool. Several other factors like your geographical location, size pump and filter etc will have to be determined also to determine efficiency.

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!
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.

We have a 20,000 gallon pool. Which BTU would you suggest? 110,000 or 125,000. thanks.

Hello, We would recommend a minimum of 125k btus for your size pool. The 140k btu will be better because it will heat up the pool more quickly.

We have a 14,000 gallon in-ground pool with 455 sq feet of surface area, looking to purchase the hp21254T heat pump. We live in Louisville KY would this unit be sufficient to heat from May to October.
Reply
Probably not. Per our Heater Sizing Chart, you can probably expect a 1 degree increase in temperature per hour in ideal conditions. Note that heat pumps lose some efficiency as the outdoor temperatures go down (note the BTU performance on this brochure) and don't forget to add in the cost of running the pump while the heater is on. Whatever you do, be sure you put a solar blanket on the pool when it is not in use to keep the heat in. Our guide on How To Select An Inground Heater has more information.
