Our salt water in ground pool is 319 sq. feet and 10,000 gallons, 3-5 foot deep. We have a variable speed Pentair pump. We live in AZ outside of Phoenix in the East Valley. In the summer the pool gets full sun all day but in Autumn in gets partial shade due to the shadow of the patio cover.

We are talking about getting a heat pump to increase our pool time. We have been using a solar cover which has helped alot.I typically use the pool from the end of March thru the begining of October (at that time of year the nights are in the mid 60s).

We would like to increase this by a couple weeks in front and several weeks behind. We would like to keep the water temp between 82-85 degrees using the heat pump. The heat pump would be in the morning sun in winter but have sun most of the day in summer.

I am unsure of the size to get and how much of an increase of pool time we would get.                                           I was also wondering about cooling the pool during the summer when the water temp gets to 97 degrees. How much could we cool it down if we got the type of pump that both heats and cools?

Hello Laurada - We'd be glad to assist you. Based on your pool size and location, something like the Hayward HeatPro HP21004T would sufficiently heat the pool. The HP21004T is a 95,000 btu heat pump. This heat pump would easily extend the season from the beginning of March to the end of October.

We have an option that will heat and cool the water. The model is HP31204T. This is a 120,000 btu unit. This model will drop the temperature to the low 80's or lower if needed (Brrrrr).
