The Nest thermostat states I heated my home for 155 hours in November. I estimate thats approx 100 gallons of oil used. It got me wondering if I converted to natural gas, how much would that be?
Unfortunately, I'm unable to find a calculator to go from gallons of oil used to therms. Or hours of heat to therms.
I'm not looking for someone to do the conversion for me. Just interested in the formula to calculate this.
Not sure if spec matter, but here they are:
My oil burner model is KV83 (I'm told it's middle quality burner so I may change it one day) It's supplied by a Riello burner oil gun. -pump pressure 145 psi -air set 3.5 -nozzle 0.90 x 80 degrees B -headset 1.0
