Yes, it does. And it gets used, too, when the weather is too cold for outdoor showers.
The outdoor shower, with unlimited spring water and the instant hot water heater/shower combo, is a wonderful addition to our summer campsite, especially when we have tent campers with us.
I think the issue we're discussing here is instantaneous propane hot water heaters. My experience is with the EcoTemp outdoor model, for long term boondocking, has been excellent.

Tankless Water heater

I purchased a ventless propane tankless water heater made by Excel America a few years ago. I installed in my vintage trailer and it works great. YOu just have to have it well below the counter that you install it under. My husband put a heatshield on it anyway, although it didn't require it. It is only hot while the water is running. You might see if you can find them online. ExcelAmerica the price was right at 300.00 and it included the shipping. It has the safety oxygen sensor on it and the igniter works off of two D cell batteries. I love it!

For your safety, NEVER try to clean the pilot orifice on ANY vent-free gas equipment. The pilot IS the safety and any changes to it will eliminate your safety. If you have a problem, you need to replace the entire pilot assembly with another supplied by the manufacturer.

I think that the urn idea is brilliant. I don't have enough kitchen counter to dedicate to one, though. I wish there was a small simple 'on demand' type of heater. I'll just keep using my electric tea kettle, I guess.

Thinking about mounting this one in the bath. I have a 110V to plug it into. I would have route water to the shower or tap into the water going to the bathroom already. What do you guys think about this one?

It uses 23 amps, so you may have to make sure everything else is off while using. Otherwise it should work.

Can I ask opinions on an idea I have been kicking around? What about putting an on demand water heater either before or after a RV water heater?

On idea is to have a small tank less before the RV water heater to pre-heat cold incoming water. That way the RV water heater won't have to work so hard and can keep up with someone having a shower. Of the several times we tried the shower, a Navy shower was still not short enough.

The other possible idea is to have the tank less after the RV water heater. That way when the hot water had been used up and only luke warm water comes out, the tank less could boost the temperature up to a comfortable level.

The first idea seems to need the tank less heater to run pretty much all of the time that hot water is being used. The second idea seems to limit the tank less use to only after hot water in the RV water heater had been consumed.

Both ideas are working on the assumption of using a tank less water heater that is not large enough to heat the water fully on it's own. It works to aid the existing system without replacing it. This also limits the cost involved because the sizing of the tank less water heater.

Not sure it will work with tankless. I have one of the only being installed right now in rv's, a Girard model. What you do is turn only the hot water on and adjust the temperature with the flow, little flow is hot, more flow is less hot. The premiss is based upon the water temperature. If you preheat the water then it will defeat the purpose.

On demand water heater

Chonomite does manufacture heaters in 15 amp that give 35 degree temperature rise from inlet temp. If you are interested you can contact me at d.wilson@morrisgroup.co (it is .co not .com). We are the manufacturer.

I have a similar water heater from the same manufacturer and went with the 20amp unit. It works fine and heats up the water nicely, but do not expect a steaming hot gushing flow. Not out of a 120vac unit at least.

It warms up the water and is pleasant for washing... The plumbing is a bit of a trick but I figured it out so we have warm and cold running water. I also chose to place the unit on a 20amp switch and fuse.

I thought the 30amp unit would push the boundaries on my system too far.

I find mine to be reliable and well built. Use a water pressure reducer at the inlet to help prevent leaks.

I happened to find this unused Bosch water heater that I was going to put in for times when I have hookups, running it directly from the water hookup. It has a 15 amp plug. Can this be done if it is the only power draw when in use?

I purchased a Fastair propane unit on eBay for under $100 including shipping, I think I paid around $80. It works great
