David - Which one are you going with? I am leaning toward this unit by Eccotemp. Least expensive I have found here: Eccotemp L5 Portable Tankless Water Heater Best Price PROMISE

Shipping to Kelowna is $18 and change by USPS.

Where are you located?

EXTERNAL tankless water heater

The under$200 tankless water heaters are for outdoor use only, which does not mean mounted inside a trailer cabin space! They will kill sleeping people if running in a buttoned-up cabin (auto-shut-off is nice, but not to depend on for continued life).

That said, if you have a spot to hang a heater on the outside of a trailer, not near a window or air vent, this looks like an economical way to stop boiling bathing water on the stove. Mounting an LP tank and the heater on a hand truck and attaching a hose to the trailer hot-water-input might be real nice after camp is set up. The hand-truck assemblage might have a spot in the truck or trailer while under-way. 1.3gpm with a 72 degree rise gives a thrifty-hot shower with 33 degree F. (glacial stream) water input.

8.3 (BTU's to raise a gallon of water 1 degree F.) x 1.3 gal/per min x 72 degrees x 60 minutes= 46.6K BTU/Hr? That seems to be the ~standard burner size for the small units.

I guess that I'm more paranoid about stuff that can "walk away", and would prefer a model that is installed inside with safe venting to outside (and is less subject to freezing damage), even if it's more expensive.

Cheers.

Three words for you "vented with a fan" plus nobody is running water when I am sleeping. Only time the heater runs is when water is running...Shower door and vent doors have locks and are also alarmed with a digital auto alarm with perimeter features so nobody but me can get within five feet of them during the night. Alarm can be set on quiet if I choose. Goes off in the trailer only so will not wake the campground...
The heater will be on for a total of five minutes a day....Plus I am building a separate fiberglass cell where the heater will sit.....What can I say, my wife will not come with me unless this trailer has hot water...This is a great alternative in my Boler where space is an issue...

Thanks for the input Rufus. I kind of took this thread from water heater to shower. Yes, there is no way I would have it installed inside. I was talking more about an outdoor tankless shower unit and I think the Eccotemp L5 would be the ticket. It's rated at 37,500 Btu so I think the manufactures specs are a little off as far as temp rise capability. I will be boondocking in very remote locations (gold prospecting) with only friends around so theft is not a problem. Also, thanks for the Btu calculations. That's good to know.

David - you did well on that shower unit purchase. I look forward to pics of the 'ultimate Boler'. And, what is a "SMEV kitchen"?

What do you think of this gas tankless heater $118 shipped? It is supposed to be designed for campers and has a battery powered igniter but I don't know anything about them. ~RV Camper 5L Propane Gas Tankless Hot Water Heater NEW | eBay

If you plan to mount a propane hot water heater inside your trailer or RV, it MUST be externally vented. This means combustion air and exhaust come from outside and depart to outside with no possibility of getting in the cabin. I know of people who have died from small propane appliances inside vehicles- it's very peaceful and apparently painless. The model you have linked to would be suitable for mounting outside the cabin, and plumbing the hot water inside. This would not be great for hard-freezing weather because your water feed could freeze while not circulating.

There are models that would be safe for mounting inside the cabin, but not for much less than $300. If this model were attached to a hand truck with a propane cylinder for travel, and outfitted with hose and fittings, it would be a nice portable unit for use outside, and easy to move from inside a truck or trailer during camp set-up.

When I use the word "safe", I don't mean "won't kill people who understand things that are common-enough and not dangerous when used correctly", which is the common understanding by people who are not idiots, but rather "safe" meaning "won't kill idiots who do everything wrong while you are not present". This is why we put fire/smoke & CO alarms where there is any remote possibility of CO build-up from any source: to save ourselves and even less-aware folks.

Cheers.

Here is the one I have, it installs inside and is made to be used inside like a conventional watery heater. here Girard Water Heater - Girard Products, LLC | Tankless RV Water Heater | On Demand RV Water Heaters | Endless Hot Water RV | Instant Flow RV Water Heaters | LP Gas Tankless RV Water Heater | Induced Draft Tankless Water Heater
They are pricey, about $500 but well worth it, no winterizing issues, endless hot water for all the showers your grey tank can hold. They are also a lot lighter and compact than a conventional w/h.

this looks very much like our Eco temp OUTDOOR shower. I see no venting options. I looked thru several websites selling the same shower, and saw nothing that showed a venting option. Most talked about "camping showers outdoors"... Which, is fine, as long as that's its purpose.
EcoTemp does manufacture units that vent to the outdoors, and are manufactured for RV use. Or at least, they used to.

I wouldn't try to use my outdoor shower indoors, as much as I love it for its intended (outdoor) purpose, where it has performed flawlessly.

I just reread some comments on temp rise/lukewarm water.
Our EcoTemp L5 manages incoming extremely cold water very, very well. We use mountain spring water, which is around 40 degrees in spring and fall. In the summer, with warmer incoming water, I have difficulty getting the heat setting LOW enough.
It sips gas, and is the best $100 bucks we've spent in a long time. However, again, it's rated for outdoor use. ONLY. We built a shower enclosure to cut the wind on cold days, which is great. I'm really warm till I turn the water off.... In spring and fall, I bring a big robe to the shower, and an extra towel for my hair. At 40 to 50 degrees ambient temp, it's really cold when the hot water is turned off.

I purchased a Coleman unit with a pump, and city water inlet. I have not tried it yet, and they don't publish and btu spec. This and the outhouse tent are my plans for camp site shower / potty. I have my doubts, the tent looks too complex, and the heater has very low pressure. We will see.
