Hi, Hollis. This unit is no longer available. I would recommend the HP21254T 125K BTU unit.

I have a Hayward Pro Heat pump, Model 21104T, The temperature is only going up to 72 degrees. it was working fine , then temperature won"t go any higher. Could it be a capasitor ? I noticed (the small one ) was leaking some brown liquid. I called several pool companies and they said they don"t work on this system .. Any advice is appreciated

I have an "Air Energy Heat Pump" (Pompano Beach, FL) that I want to replace. Model 500 Standard......(.230v/1/60)...........118,000 BTU hr. (I purchased this unit in 1996........the company may be out of business now.) My Pool is 29,000 gallons...........is there a Hayward heat pump available that will do the job? Thank you.

A  Answered on 6/18/2017 by InyoPools Product Specialist Patrick P.

Hi Richard, Thanks for the question. Hayward makes some great heat pumps and I would suggest the Hayward HP21254T 125,000 BTU Heat Pump as a great replacement to your old Air Energy Heat Pump.

Our pool equipment is behind a North facing wall,. It is shady there all day. Is it ok to put the heat pump in shade?

Can this heat pump be installed inside a shed?

A  Answered on 9/11/2014 by InyoPools Product Specialist Patrick P.

Unfortuantely Hayward does not recommend installing the heat pump indoors.

What does time clock override mean?

A  Answered on 5/16/2007 by InyoPools Product Specialist Patrick P.

Water is only sent through a heat pump when your pool pump is turned on.  The time clock override feature will turn your pool pump on if the water temp. in your pool drops below the temperature you have set on the heat pump (Thus overriding the pump timer)
