Gas or electric

We always use the electric. Why pay to empty a propane tank when you have already paid for the electric use? If you are on a metered site, then you will need to figure out the cost difference and act accordingly. The water heater and furnace will gulp down the propane quite rapidly.

I prefer to use the electric when possible because it is silent. Both will heat the water just about as fast as the other one so that is not a factor for us.
