Product FAQs

7/10/2014

Q: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?

A: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

10/8/2013

Q:Is the refrigerant in Hayward heat pumps environmentally safe?

A:Yes. Hayward uses R-410A refrigerant in all their heat pumps.

10/8/2013

Q:Can a heat pump be installed under a deck?

A: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.

10/8/2013

Q:Can a heat pump be installed indoors?

A: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.

10/8/2013

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

A: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.

6/28/2013

Q:Is the Hayward HP21104T the replacement for the HP21003T?

A:Yes, the Hayward HP21104T is the replacement for the HP21003T.

1/24/2013

Q:Is the Hayward HP21104T a replacement for the HP21002?

A:Yes, the Hayward HP21002 has been replaced by the HP21104T.

5/27/2012

Q:Is this the replacement for the Hayward HP2100TCOT2?

A:Yes this is the proper replacement for the HP2100TCOT2.

5/27/2012

Q:Would this be the proper replacement for the Hayward HP2100TCO2?

A:Yes this heat pump is the suitable replacement for the Hayward HP2100TCO2 heat pump.

5/12/2012

Q:This heat pump is labeled for an in-ground pool. Can it also be used for an above ground pool?

A: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.

2/16/2012

Q:How quickly will this heat pump heat my pool?

A:The amount of time it will take a > >heat pump to heat the pool will be based on numerous factors. The main factors to consider are the size of pool, the outdoor temperature, the size of the heat pump and the desired amount of temperature increase. It is best to use a >solar blanket in conjunction with your heat pump in order to > >keep heating time and costs even lower.

   (5 out of 5 Stars) Great pool heater!

Reviewed By: 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!

   (5 out of 5 Stars) Great heater

Reviewed By: from Bel Air, MD ()

Pros: Quiet, cheap to run.

Cons: No timer.

I have 16K gallon in ground concrete salt water pool which is mostly a weekend party pool. Because of this, I wanted a gas heater because of quick warm up but my local gas company wanted big bucks to upgrade my meter. I decided therefore to go with a heat pump as I had the wiring in place from an old hot tub.

I had this thing plumbed and powered up in less than 2 hours from the truck dropping it off.

It is very quiet and easy to operate. With an ambient air temp of 80 degrees, it takes about an hour to heat up one degree in my pool. What I do is turn in on on Thursday and set it to 82 and just leave it running until Sunday. This is the best method for heating with a heat pump. We don't use the pool Mon through Wed so we turn it off.

I haven't noticed a huge impact on my electricity bill, it is certainly way cheaper than burning gas. Only complaint is that there is no timer so what I do is use the timer on my e-pump to drop the pump speed down so that the flow is lower than the pressure threshold of the heat pump. That shuts it down - well sends it into standby anyway.

I have only had it a few weeks so I will report back on its longetivity if I feel the need to.

   (5 out of 5 Stars) My new Hayward Heat pump is great

Reviewed By: from Havana, IL ()

Pros: Great price, great service!

Cons: None that I have found.

My old heat pump didn't survive this past winter. Fortunately I came across INYO's website. The hayward is much better then my old heat pump more efficient and a slightly smaller footprint. Inyo mae ordering easy and their super quick delivery made this job a breeze!

   (5 out of 5 Stars) Excellent Pool Heater

Reviewed By: from Madison,WI ()

Pros: Very straight forward hookup, did hire electrician.

Cons: Heavy unit, get a few good strong buddies to help move in place

I just recently installed this before the pool opening this year. This is the first year we had full use of the pool by Memorial Day weekend with warm water at 85 degrees! It took this pump (with pool cover at night) 2 days to reach and maintain that temp. The unit is extremely quiet and doesn't run that much to maintain the temperature. I'm just disappointed I didn't purchase this years earlier. It's nice to finally see the pool get so much use. Very happy customer!

   (4 out of 5 Stars) not yet installed

Reviewed By: from Belington WV 26250 ()

Pros: excellent price

Cons: the truck that brought the heater could not deliver to my home. I had to make arrangements to get it off the truck and bring it to my house.

I have not had this installed yet and will follow up once it is. It was shipped in a timely manor at a great price.

   (5 out of 5 Stars) Hayward Heat pro updated reiew

Reviewed By: from Chattanooga TN ()

Pros: heats the pool, quiet, no problems.

Cons: none

I have completed my installation. I added an Insteon wireless thermostat and an I/O module to the pool remote input. The module turns the unit on and off at the more efficient outdoor temperatures. 65F and above. Running the unit at these outdoor temps brought the pool form 54 to 84 in two days, with a thermal blanket. for the least total operating time. the heatpump controls itself to maintain the set temperature. The pool is 16 x 36 8.5 ft deep end pool. It has been in the low 50s at night and warms up in the day. When I first ran it in the mid 50's it was a slow heat up. It is quiet, less noise than my pump. It is in the mid 60's today a bit cold for me to swim but my pool is 86. I'm happy.

   (5 out of 5 Stars) Hayward Heat Pro

Reviewed By: ()

I received the shipment very quick and without damage. I have it installed except for the wiring. This was a complete new install since I did not have a heater prior to this one. I plan to install the wiring including a new breaker panel this weekend and I will update this review to add the performance of the unit.
