Should I Buy It?

Given the substantial number of negative reports regarding defective units and the lack of support for these issues, caution is advised when considering a purchase.

    • Pentair Master Temp 150k BTU propane
Style: New
Had a master temp at my old house too, worked great so I purchased this for my new pool here at our new house and purchased a propane one and bought a 40lb tank and a 60lb tank with a low pressure house and regulator and works great. Mainly to help raise pool temp a few degrees in May

Style: New
Don’t buy this, worked 30 hours then quit. I bought an extended warranty but it doesn’t work. They tell you when it quits to pay for a pool person to look at it and send the invoice just to get the part it needs. But if the part is on back order then you have to fix it yourself or wait for the part to come in. ... show more

    • Bang for the buck
Style: Old
I just hooked it up last night to a 100lb propane tank. It warmed 15000gals from 65° to 75° overnight when the outside temp was in the low 50s. It used about 12 gals of fuel which is about 30 dollars in Oregon. The heater is very quiet and very easy to hook up. Once the pool is at temp of 78° I sure 100lbs will last a long time. Very happy with this product. ... show more

I have had 2 of these heaters in the past 7 years and they both quit working on me. Time for a different brand, I guess!

    • There is no warranty or support with this product
Style: New
Purchased heater in good faith that at least some form of support would be available for manufacturers defects. System would not start, had four installers examine unit, all stated it was a warranty issue. Pentair stated they would not support units purchased through Amazon. As of now 7/30/2022 the system doesn't work and waiting for one more expert to come and examine. ... show more
