Natural Gas Pool Heating Costs.

To Calculate Your Gas Consumption

Fill in the work sheet below to determine the cost of operating a natural gas swimming pool heater.

Gas Pool Heating Cost
A	Cost Per Therm of Natural Gas One Therm = 100,000 Btu's* Example: $ .80 per Therm
B	BTU/Hour Rating of Natural Gas Heater Example: 325,000 Btu's/hour rating
C	Therms per hour = ( B x divided by 100,000) Example: 325,000 Btu's divided by 100,000 = Therms per Hr Example: 325,000 / 100,000 = 3.25 Therms per hour
D	Hours per day pool heater is used Example: 4 hrs/day (typical for spring and fall)
E	Daily Operating Cost = ( A x C x D ) Example: $ .80 x 3.25 therms/hr x 4 hrs/day = $10.4
F	Days in the month heater is used Example: 30 days per month (typical for spring and fall)
G	Monthly Operating Cost = ( E x F ) Example: $10.4 x 30 days per month = $312.00

* Btu - The "British thermal unit" is the quantity of heat required to raise the temperature of 1lb of water 1 degree F. In Southern California, a typical pool season will cost in excess of $1,500 of natural gas to heat the pool. Installing a solar swimming pool heating system with a life expectancy of over 15 years, and with an average cost between $3,500. and $5,500. makes economic sense. A solar pool heating installation will save a substantial amount of money while providing a warm and comfortable pool.
