Dear RV Doctor,
I have a Jayco trailer that has a dual electric/propane water heater. The propane heats the water faster, but the electric is at no cost to us when using the power that our state park provides. We don’t need hot water right away, so we have been using the electric mode for the first year we have used the unit. Is one method better for the long-term life of the water heater? And why? Thanks! —Larry G.
Well, as you use the electric heating element, over time it may fatigue slightly just from constant use. And as you operate the propane function to heat the water, those components will require some maintenance over the course of time.
