Enjoy instant, endless hot water at the turn of a tap anywhere in your RV.
Energy-efficient, propane-fired heat exchanger heats water only as it’s needed. Uses no energy to keep water hot in a tank plus it saves up to 100 lbs. of water weight. The flow regulated modulation valve automatically adjusts the burner input based on water flow rate for optimal operating efficiency. High output burner delivers hotter water on cooler days.

Works just like at home—simply turn on the hot water and mix in cold to reach desired water temperature. Easily adapts to replace virtually any brand of standard 6 or 10 gallon water heater. Includes top adapter plate for 10 gallon and larger tank replacement. Exterior door sold separately. 12-volt.

Note: 50,000 BTU Water Heater also includes a winterizing kit.

too much flow

It seems to work fine however, it is limited to full flow or nothing. If you cut it back to slower flow, it pops the overheat button when it is shut off. Was easy to install but it seems to me that if this is a retrofit, it should include the cover. The flow thing is important to me because full flow is really too much . This is an RV--lots of hot water but small holding tanks

Needed for RV'S like the slide outs. All the hot water you want, no water to lug around. Have had mine since May 2014, no problems on a 5th wheel 39' Bayhill.
Pros: Manufacturer service, Simple to use, No weight
