Use this formula to help you determine the operating cost of running a pool or spa heater.
Note: The heat loss of a pool or spa varies with the weather, so the predicted cost of operation may significantly vary from actual operating cost.
Formula for predicting how much it costs to run a gas pool or spa heater:
Cost of gas per therm x Input of heater = Cost per hour
A 250,000 BTU heater with a gas cost of 0.86 per therm
(1 therm = 100,000 BTU)
0.86 per therm x 2.5 therm per hour = $2.15 per hour
