I installed one in my wife’s coffee concession trailer and it works perfectly however it absolutely needs to be used in an open area not in a closed up van. It is portable though and mine has a bracket loop at the top so you can hang it. I’d post a pic but never figured out how on this site.
I don’t have any experience with it yet, but I recently ordered a Joolca hottap v2 instant hot water heater from Joolca.com. If you haven’t already looked into their products it might be worth looking into! All of their products seem really well thought out and designed.
Beware, all of these on demand units I have ever seen or installed have not been installed in a closed cabinet or in a living space. Thinking out load, if you are burning propane, where do the hot burnt emissions go? Carbon Dioxide?
Wisco, I to have looked into the Joolca, everything in the video and information is they are set up outside not in enclosed spaces. Just sharing.
