what size heater should be a good for 24 ft round pool and I am in the north east?

Inyo Answer

Question

Asked on 05/02/2015 by Brian

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.

Inyo Answer

Answered on 05/02/2015 by Product Specialist Patrick P.

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.

Question

Asked on 04/26/2015 by Crissy

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 .

Inyo Answer

Answered on 05/02/2015 by Product Specialist Patrick P.

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.

Question

Asked on 04/24/2015 by Alex

Hi, does this unit includes wiring/connectivity for remote operation and will it be compatible with Jandy iAqualink system for remote operation? Thanks

Inyo Answer

Answered on 04/24/2015 by Product Specialist Lennox H.

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.

Question

Asked on 04/23/2015 by Frank

Can the pool pump and filter run without running the heater.

Inyo Answer

Answered on 04/23/2015 by Product Specialist Lennox H.

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.

Inyo Answer

Answered on 04/17/2015 by Product Specialist Wes B.

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.

Question

Asked on 04/16/2015 by Sal

What type of pool cover is needed that's easy enough to take on and off every day to maintain pool temperature?

Inyo Answer

Answered on 04/17/2015 by Product Specialist Lennox H.

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.

Question

Asked on 04/03/2015 by Enoc

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.

Inyo Answer

Answered on 04/04/2015 by Product Specialist Lennox H.

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.

Question

Asked on 04/02/2015 by David Kerker

Is the Hayward HP21104T big enough or to big for a 13' x 25' 5'6" deep end?

Inyo Answer

Answered on 04/02/2015 by Product Specialist Wes B.

Hi David, Yes this Hayward heater (HP21104T) will be sufficient enough for a pool your size.

Question

Asked on 04/01/2015 by

Unit is flashing "P5". What does this mean?

Inyo Answer

Answered on 04/01/2015 by Product Specialist Hector F.

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.

Question

Asked on 02/05/2015 by Don

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?

Inyo Answer

Answered on 02/05/2015 by Product Specialist Alex V.

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.

Question

Asked on 09/18/2014 by Guest

What is the weight of this pump? Thanks

Inyo Answer

The weight for this heat pump is 240 pounds.

Question

Asked on 09/17/2014 by Guest

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?

Inyo Answer

Answered on 09/17/2014 by Product Specialist Patrick P.

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.

Can I install this heat pump indoors?

Inyo Answer

Answered on 09/11/2014 by Product Specialist Patrick P.

Unfortuantely Hayward does not recommend installing the heat pump indoors.

Question

Asked on 07/10/2014 by Guest

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?

Inyo Answer

Answered on 07/10/2014 by Product Specialist Patrick P.

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

Question

Asked on 10/08/2013 by Guest

Is the refrigerant in Hayward heat pumps environmentally safe?

Inyo Answer

Answered on 10/08/2013 by Product Specialist Patrick P.

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

Question

Asked on 10/08/2013 by Guest

Can a heat pump be installed under a deck?

Inyo Answer

Answered on 10/08/2013 by 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.

Question

Asked on 10/08/2013 by Guest

Can a heat pump be installed indoors?

Inyo Answer

Answered on 10/08/2013 by 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.

Question

Asked on 10/08/2013 by Guest

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

Inyo Answer

Answered on 10/08/2013 by 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.

Question

Asked on 05/12/2012 by Guest

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

Inyo Answer

Answered on 05/12/2012 by Product Specialist Patrick P.

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.

   (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!

   (3 out of 5 Stars) Heat Pump

Reviewed By: from Dayton, OH ()

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.

   (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) 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!
