Will a 250,000 propane pool heater heat the water in a 20,000 gals pool ?
Steve S on May 12, 2016
BEST ANSWER: Your question really leads to other questions. Where do you live and how warm do you want to keep the pool? Above ground pools have a higher heat loss than in ground pools. How fast do you want to heat the pool? If you live in a cooler climate and are looking to extend the swimming season I would either recommend a 400,000 - 450,000 btu or 2 of the 250,000 btu heaters. With a 20,000 gal pool it would easy to setup multiple heaters. I don't know which would be more cost effective. If there is not a big price difference you could start with one and then add the second if needed. Hope this helps. If you would answer the questions I asked I could give you a better answer.

Pentair 250000 BTU pool heater LP gas, is this recommended for salt water pools?
Gary C on May 24, 2017
BEST ANSWER: This heater will work but we do suggest getting a heater with cupro nickel that would protect the heater from corrosion. And always use a corrosion resistant check valve.

Runs quieter than previous model. Works great and puts out a lot of heat in a short time efficiently. Very satisfied customer.<br>
March 9, 2017
Highly recommended
It was delivered two days after ordering it! I had reservations about purchasing a large heavy unit like this online, but it arrived in perfect condition by ABF.
I installed it myself easily in about 6 hours. Only because I had to replumb do to the vertical manifold vs horizontal.
Very easy operation and it heats my 850 gal spa 15 deg in 10 minutes.
I’m a rather discerning person and would recommend this unit and pool supply company to family and friends.
