On-demand water heaters – do they work?
We have a new Thor brand class C motorhome with an tankless Girard Brand RV water heater. In the shower the water will temporarily turn warm after the hot water faucet is on and run for a while, but it cycles between warm and cold, so we end up showering with mostly cold water. Both the manufacturer and RV repair facility tell us the same thing: run the faucet until warm water flows, then reduce the flow to sustain the warm temperature. When hooked up to city water, this almost works but with dry camping it does not work well and takes too much water to sustain even water occasionally warm. Washing dishes offers a similar experience. Anyone have good success with tankless water heater in their motorhome? Is so, how did you get it work?
