can it be mounted on its back laying down?

Asked by phillly September 19, 2020
4
Answers

Ours is mounted upright on a closet wall. Ask the manufacturer but I think they would say no to laying it down. Note: In our small house, only one person can use hot water at a time (dishes, shower, or bathroom sink). Easy to change the water temp for different uses.

Can it also be. Installed in an RV ?

We have to run it hard for about 2 minutes to trigger the unit to start heating water. You can turn it down a little to keep the hot water flowing, but if you turn it down too much you just get Cold water. Have to get used to settings that work for you.

Works well. Comes with no instructions and no fittings or adapters. Doesnt tell you what type of exhaust vents you need. Overall the unit does work well. Just expect to spend $150+ on fittings and adapters and exhaust vents (assuming you are doing it yourself) if you have to hire a professional...probably just better off with a tank water heater instead.
