Most of the under-counter instant-hot water heaters I've looked at run in the 400-500 watt range. That one pulls 780 watts, which means it'll heat up pretty fast but pulls enough current to trip your trailer's circuit breaker or the circuit breaker on the campground post if it's busy heating when you run your microwave. So if you want both microwave and hot water you might want to limit your microwave size to 700-800 watts.
Hadn't thought of that. I won't have a microwave anyway so hope I'll be ok. Thanks.

Ok, I'm totally confused. Aren't there water heaters that just use propane and no electricity? Is the electric for the pump?

New here. 81 Burro.

A propane water heater with Direct Spark Ignition (DSI) needs a small amount of 12V DC power just to run the controls and make the spark that ignites the propane flame; the heat comes from burning propane. A heater with DSI doesn't have a pilot flame.

Propane heaters with pilots - such as the one in our 1979 Boler - don't need any electrical power at all to operate. I would still choose DSI over a pilot every time!

Most of the options discussed so far in this thread are not propane-fired at all - they are various styles of electric heaters than run on lots of 120V AC power.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

Hi Kirsten, to FiberglassRV, we're glad you're here!

I have an all electric hotwater heater, but I'm not a boondocker... I'm always hooked up to a power bush.

You'll find there are lots of kind and helpful people here on the forums to give opinions and advice.

Thanks for the warm welcome! I would like to be able to stay off grid as much as possible. I have a giant propane tank and never seem to use much of it so propane makes sense. There are those propane outdoor on-demand shower things which sound ideal, but then the issue is getting water pressure right? I have just had a 12v water pump installed but it is seemingly very weak. Just enough to get a consistent dribble in the sink.

Any suggestions or solutions would be welcome. I'm liking the garden sprayer idea as a simple power-free solution but I don't want to put money into something that is just not quite right.

Glad to be here! You all have helped me a lot already!
