So I've found plenty of what I need/ want except they are all for outdoor use. Which means the exhaust is vented through the unit.
Has anyone converted an outdoor unit and found an easy way to vent the unit outside?
Do they make a indoor propane tankless water heater that runs independently from the grid. Like the portable ones do.
so the theory/ plan is to have a submersible 12v 50psi pump from the water storage barrel. Then to a 4 gallon inline pressure well tank. Then to the tankless water heater.
My conditions for the heater are
2. Battery powered igniter
3. Rated for indoor use
4. On demand
I've scoured amazon but haven't found my criteria. It's possible though I'm just not using the right search words.
In the summer you have to fiddle with both knobs to get the water to the maximum temp you want while the water is running. If you are taking a shower and there isn't enough water flow through the machine you have to turn on the sink hot water too, just to get it to fire up. Then, if the water pressure changes even a little it can get too hot - don't turn down the hot water though as that will make it hotter! This type of heater is damn retarded and when the water flows slower through it the amount of flame stays the same so the water gets hotter; until the flow gets so slow that it turns off altogether. So you get water that is a little too hot and you naturally move the spigot towards cold and it gets hotter until all of a sudden its freezing.
And in the winter it barely gets the water hot enough to take a shower.
Oh yeah, do NOT use a low flow shower head. You won't get enough flow to make it fire up. And when washing dishes you have to keep the hot water flowing at maximum or it'll turn off.
Definitely look for one where you can easily set the water temp. The one I have only shows the outgoing temp produced by the combination of propane flow/burn and water flow control; a real pain in the butt.

We have an EcoTemp on demand gas water heater as is mentioned above. Much of what was said is familiar The price was right and we didn't (at first) mind having an outdoor unit......the second lowest priced one that could heat two faucets at once.
Our problem has been what we understood to be the freeze plug which we were always careful to remove....and the fact that the whole unit needed to be unplumbed and drained over the winter. It is hard to drain completely without doing that, and two dif. winters we have had to solder the copper tubing inside the unit after it froze and burst. This alone is enough reason to pay the extra for an indoor one, I think. We didn't want to depend on elec. for ignition either so am glad to see there are other options.
Back to the bucket shower until our tubing is repaired

I have a 425 hn n Bosch pro tankless water heater that I removed from a job. It's natural gas, but I believe can be converted; I haven't looked it up, but most are easily converted. It comes with installation valves as well. Retail would be around $800, but since this has been used(fully functioning when removed) I will sell it for $150 plus shipping. This is the kind with the internal hydro-generator, so it requires no external power source.
Send me a PM if you would like to talk more about this,
