We just had a small heat wave here in the West. I was out in the garage and noticed that our furnace pilot light was still on. Not any more!
After a few calculations from our Pacific Gas & Electric bill, it appears that our furnace pilot light consumes 0.3 ccf/day. At the current natural gas price which includes a nickel surcharge and a 5% user’s tax, this is equivalent to $0.4069 per day. Over the course of the 6 months that we definitely don’t need our furnace, this reflects a savings of $74.
Other ways to save natural gas are
- replace the furnace filters every year when it is turned back on
- wrap your water heater with an extra insulator blanket
- set the water heater temperature to 120 F
- use a clothes line to dry laundry
Some day we will get a new furnace with an electric igniter, but until then, it pays to turn off the pilot light when the furnace is not needed.
Ask your significant other before you turn off the furnace pilot light. It got cold the night after I did this. It was 62 degrees inside the house the next morning. My wife suggested I re-light the pilot light. I did.
