Residential tankless water heater

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.
