Suburban Water Heater Review

There’s a lot of people that install instant water heaters on their rigs and I would have been one of those if I had the wall space to permanently install one.

I ended up installing a Suburban SW6D 6 gallon water heater with piezo igniter.

The installation instructions suggest that it be installed on the floor. I couldn’t do this because I’d need to cut the chair rail. So I decided to hang it under the bus. The water heater doesn’t have an enclosure so I made one out of some 16 gauge steel I had laying around

Connections were straightforward. With the only confusion being an extra ground wire connection.

I was wondering how it would operate while driving. I still don’t know if it does ignite at 65 mph, but it doesn’t seem to matter. When the ON switch is flipped it is self regulating. I ran around town with it on for a couple days as a test (better to burn down in town, I thought), but it worked so well I just left it on for the 2 hour drive to the campground and it just kept on working.

Sorta wish we went this route, we have problems mixing hot/cold with our tankless. Not a problem on the 5th wheel with a water tank.
Nice install.
