How much will a 266 BTU pool heater raise your ccf usage on your gas bill?

To calculate how much a 266 BTU pool heater will raise your CCF usage on your gas bill, you need to determine how long the heater will run and the cost of gas per CCF. For instance, if the heater runs for 10 hours and uses 266 BTUs per hour, it will consume 2,660,000 BTUs in total. Since there are 100,000 BTUs in a CCF, this would equate to approximately 26.6 CCF. Multiply this by your local gas rate per CCF to estimate the increase in your gas bill.
