It worked like clock work on my pool
on March 30, 2015
I did the math. 1btu is the amount of energy needed to heat one pound of water one degree. Water weighs 8.34 lbs per gallon. 100,000btu hr at 82% efficiency, is 82,000btu per hr divided by 8.34 is 9,832. So it will raise the temp of nearly 10,000 gal of water one degree per hr. It worked like clock work on my pool, raised the temp 5 degrees in five hrs! I have an in ground pool that holds approx 10,000 gal of water. I recorded the heat loss over night, on average 1/2 degree, and sure enough, the heater runs about a half hour a day to keep it at temp. I run it off 2 100lb propane tanks ganged together with the connector (Mr Heater) and dual stage regulator (Camco) both bought on Amazon, with 1/2" copper line. It works better than expected! Love it!
