Best tankless water heaters (LP) 2.5gph or higher

Don't forget, as soon as you plumb in propane, 120 volt electric, potable water and or wastewater plumbing you may have problems finding camping spots unless the unit is certified to meet the appropriate standards, I.E. NFPA 1192 / ANSI 119.2.


If you only ever boondock on private land it will likely never be an issue, but elsewhere it's a legal requirement.

You may also have insurance issues without it.

I plumbed a line with a "Y" and valves from the hot water low point drain back to the fresh water tank drain.

Excellent post THANK YOU.
A problem was fixed and shared.

It will work if you are hooked up to a water source such that when showering you can let the water run the whole time, and are great if you plan to take long showers and waste water…

Bad if you want to conserve water if not hooked up. As soon as you stop the flow the water in the tankless gets hotter, then when you resume you get that hotter water, and when you let it run longer the temp goes back down. No steady temp is possible with the military shower method. Unfortunately the hot water heater is the only way for this. I wish I had a two gallon water heater as I take 1 gallon showers…

In the summer I have learned to just take cold showers. This helps a lot to save water since I boondock it is important. After two showers you get used to cold water and it is not different than washing your hands in cold water.

Agree.

We dry camp mostly so water conservation is needed.

When diverter valve is on, hot water constantly runs through the system and dumps back into the fresh water tank. Seems to stabilize the temperature when shutting off and turning on the shower hot water.

When done showering, turn off the water pump.
Turning the valve in the "Y" diverter puts the system back into original configuration so pump can be turned back on for normal operation.

This also save the extra water wasted waiting for the hot water to get to the bathroom. Still needs to purge cold water from the shower head hose so less ware wasted.

Had a tank water heater in a pop-up and it worked great.
Bought a MH and it came with an on demand water heater.
Failed the first trip due to a sticky sail switch.
Got it working with dry Teflon lube.
Water temperature varies from warm to scalding hot.
I got the temperature to be slightly more stable by plumbing in a hot water recirculation system.
Wish I had a tank water heater. Less to go wrong and constant temperature.
I will have to say winterization is easier with the on demand system we have.

If you use a tankless water heater is it best to have it placed very near the shower?

I love my 2.5 gallon Truma Combi gas and/or electric water heater that doubles as a furnace also using gas or electric or both.

tenj gal tank. and while your redoing this. hook it up so it will heat your rv like in a house base board hot water system.

lots of previous posts on this Forum. Unfortunately, I think, some of the new rigs are manufactured with them; like it or not.
The best tankless water heater for an RV is an oxymoron.

Hi,

I'd go for ten gallon electric/propane with a motoraide circuit.

Getting to the point I need to decide how Im going to heat my water in the toy hauler. I was pretty set on tankless but if they are just a huge hassle I can use conventional. What is your opinion?
