Does the whole 4 gallon tank heat up or just the water as you use it. What temperature is it supposed to be. Thanks!!
Are you talking about the Ariston point of use heater, if so I just installed one this morning and it took about 20-25 min to first heat up, I'm worried now that it won't be able to keep up with demand, but also is not like I'm gonna be washing dishes every 5 minutes.
I hope I pass inspection with it if not then I have to look at alternatives.
I had it at the recommended setting, but there's a higher setting that I assume will get the water even hotter.
