Asked on 06/20/2015 by NORMAN

JUST INSTALLED NEW HAYWARD POOL MODEL HP21104T IS FLASHING CODE P-5 WHAT IS THE CAUSE. HOW DO I FIX IT

Inyo Answer

Answered on 06/20/2015 by Product Specialist Hector F.

This code means that the pressure switch itself is bad or the water flow is low. Start with cleaning and or removing the filter then testing to see if after that the flow increases. Also make sure that there are no turned valves bypassing flow through the unit. There could be a number of reasons that water flow decreases but start there and if that does not solve it, move to testing potential pump issues.

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.

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.

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.

Is the refrigerant in Hayward heat pumps environmentally safe?

Inyo Answer

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

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

Inyo Answer

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!

   (5 out of 5 Stars) Hayward Heat Pro 110k

Reviewed By: from New Port Richey FL ()

Pros: Looks good, quiet, heats up well

Cons: None really

Delivery process and order process easy. Be aware though you will need help to move this unit. I managed by myself with a trolley and strap but it was heavy!

Electrician wired from main panel to the other side of my home for $450. I plumbed in the heater and connected the power. Spent circa $100 on fittings etc.

Very simple to operate and heats up my 9000 gallon pool in no time. Yet to see what impact is on my electric bill but use of s good quality solar cover will help.

   (5 out of 5 Stars) Easy quick installation

Reviewed By: from Fort Lauderdale, FL ()

Pros: Easy setup and connection, fairly quiet

Cons: Electrical hookup space limited

Ordered the pool heater and it got delivered yesterday 4pm. By 10pm I was done with installation, eg setting on the slab, making electrical connections and plumbing. Granted, everything was in place. The electrical hookup is very tight in space, they do have a coolant pipe right at the place where the conduit is supposed to go, but it works. The startup was without issues and the unit is fairly quiet. Comparable to a small air conditioner. I have a 15x30 pool, and starting temp was 70 degrees. We will see how long it will take to heat it up to 86.

   (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.

   (4 out of 5 Stars) Very Happy So Far

Reviewed By: from Oxford, Ohio ()

Pros: Heats well

Cons: Costly to run, but they all are.

We just installed our unit in the middle of the summer here in Ohio. I was very pleased that we got at least an extra month out of our pool at the end of the season by having this heating unit.

   (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.
