On-Demand water heater

We are rehabbing a 1996 Excel 500 Air Stream and want to put an on-demand water heater in. Are there any suggestions - do's and/or don'ts? We are so excited to be newbies to the Air Stream world and can't wait to get on the road!!

The best you can get is a Truma, they don't shock you with hot and cold while showering. It's always hot or mostly hot.

They are expensive, some find the..more convenient due to unlimited capacity, smaller footprint, and less gas usage.

If it was me I would go with the 6 gallon Atwood instead.

I looked at Truma a couple of years ago but gave up on the idea because only a Truma dealer would do the install; the stuff is not available for sale to the consumer. No dealer near me. Nice unit though.

We installed the inexpensive Excel ventless on demand heater. We absolutely love it. There are some threads about these heaters you can look up. So there's no point to anybody banging on about ventless heaters killing you here. Its been discussed extensively elsewhere.

On-Demand water heater

Have a PrecisionTemp unit. Very even hot water temperature when itís running. External vented. Too hot in CA and places we go for ventless units. Iím also not in favor of exposed combustion in my living space...
