Is it efficient to turn a propane heated water heater off and on prior to use?
I only use my water heater for showers..is it more efficient to turn it on prior to use and then tur it off or does it use the same amount of gas if left on? Does it use alot of propane just ot have the pilot on?

Best answer:

Answer by Andrew Twidwell; The thermostat in the water heater is designed to be the most efficient way to heat the water for your shower and your household needs. If you are going to be away for several days, turn the thermostat to “pilot” position and remember to turn it back on a day before you need to shower.
