Is the Btu rating of a pool heater the input Btu of the gas or the transfered Btu going into the water?

input of gas heater The heater has its own BTU rating separate from the gas and the heat transferred. Every heater has an efficiency rating... for instance, a heater can be rated at 92%. This means that for every BTU burn in the heater, 92% of that BTU is transferred in to the water. The main premise behind BTU ratings and pool heating is that most forget the parallel factors involved. How many gallons, and what is the temperature rise? A 200k heater and a 400k heater can both handle, maintain, and work at the same efficiency. The true difference in them is the time it takes to create the rise in temperature. If the pool is 60 degrees, and you want the pool 80 degrees, then you'll need 1 BTU to raise each pound of water 1 degree. The only remaining variable is the quantity of water which will tell you the total weight of the water.
