Long Live the RV Water Heater

Hey Doc, what is the average life span of an RV water heater? Jim N., (no city/state)

Jim, that’s really hard to quantify. Under proper use and a proactive preventive maintenance regimen, there’s no reason an RV water heater cannot have an indefinite life. The corrosiveness and amount of mineral water it is exposed to obviously will have an influence, but if you flush it out properly once or twice a year, perform proper winterizing techniques, regular chlorinating procedures, and clean & service the gas components annually, the inner tank should last indefinitely.

If you have a Suburban water heater, keeping a close eye on the anode rod once a year or so will help extend your water heater's life as well. Long live all RV water heaters! Unless you decide to opt for a tankless water heater.
