I think the max temp rise is 70 degrees. So if your incoming water is 40 degrees it will raise the temp to 110.

Also, I've read a lot of posts where people say that the water comes out too hot no matter what. Is that only if the flow is too low? Do you think it will work for low flow showerheads or if you are trying to conserve water while boondocking?
Thanks!
Tim

One question I have always had about the tankless water heater is how much water is wasted before you actually get hot water from the tap? Grey tank storage is limited!

The heater needs at least 1-1.5 gpm to turn on, but I think that number is lower with the new unit. When the water stops flowing the burner shuts off. Once you fill your lines form the heater to the shower head, you should be able to do a navy shower. My tub and shower is not installed yet, so I can't speak from experience but from watching the unit work it should. My kitchen sink faucet is a 1.5 gpm (max) unit, and the heater turns on when I have the hot water turned half way on. How low flow, I'm not quite sure, but it seemed less than 1 gpm.

You still have to void the line of the cold water. So it would depend on how long that pipe is and how large the pipe is. It heats the water seconds after you turn on the hot water.

Just a quick update. This is about the third camping trip out. Unit is working great for what we need, just running the kitchen faucet off of it. Went to fire it up and the blower sounded like a mad man!! Upon closer review it appears that a mud dauber but a nest on the fan. One screw and a few mins with a metal ruler I was able to clean the fan. Now it runs great. I will find either a cap or a screen to cover the exhaust pipe. Now for the mice....

Well I just wanted to give an update on this on demand hot water heater. So far so good. Works really well. No problems so far expect the mud dauber nest. We have been out about a half dozen times, and have done nothing to it. It just runs great.

I insulated the hot water lines so this seems to help keep the water hot in the lines.

The only down side I see is that every time you try on the hot water the blower kicks on and runs for a min or two. If you were boon docking that may be a consideration.

Other wise a big thumbs up!

Would it be bad if I installed a residential tankless water heater?

I thought about that, but the electric ones draw a lot of Amps. I live and camp mostly in Fl so AC trumps hot water. I guess a propane home model vented correctly would work. The blower motor would have to work on AC and DC if you were planning on boon docking. If you were always at camp grounds where you can plug in not a big deal.

I used a propane model. I am set up with a 5,000 watt inverter, I use very little 12 volt, water pump and a few emergency lights is all.

I vented straight out the roof with a 3" isolated vent tube.

Looks good. What did you paint the roof with?
