Residential tankless water heater

[theoldwizard1]

I just discovered that several companies make an OUTDOOR residential water heater. Not the cleanest looking thing hanging out the back of your TT or 5er, but you will have tons of hot water !

Has anyone installed one on their RV ?

I might consider a hybrid for home use, but I'll stick with the tried and true 6 or 10 gallon gas/electric water heater for my RV.

Rheem make a couple of different models. They do require 120V AC for ignition, but the installation guide says only 1/2" gas pipe is required (the one I linked is 160,000 BTU).

Shipping weight is 54 lbs. There is quite a bit of plumbing (hot and cold water, gas, electric, PT valve outlet, etc.) below so I would want some kind of cover for all of that.

Maybe something like this?

Camplux 10L Outdoor 2.64GPM Digital Display Portable Propane Gas Tankless Water Heater

I plan on getting this model and plumbing it in to the low point drain port then bypassing the main water heater. Should be a good mod experiment!

We have a friend with one at their house (propane). I don't know what brand it is but it works fantastic at all flow levels.

A link would help. Never heard of it.

They're rather huge, many require 240 and probably not good for vibration.
