I am aware this has absolutely nothing to do with firearms, but I know there is guys here that has knowledge in this field. This goes out for JoedaPlumber because obviously your in this field...but I am posting in general chat incase any body else has info that they would like to share...and please do. Alright, I have a tankless water heater in a house I just bought. The house is 3 bed, 2 bath, and there is 3 of us...soon to be 4. The water is from a well. It is a S.E.T.S unit (240v) but the Model # isn't on the unit. I also know that S.E.T.S is now owned by Hubbell and they do not honor the warranty. When we take a shower the temperature is very erratic (either burning my hide off or freezing me). I played around with the settings on the unit from low all the way up to the highest but that didn't help. I leaning towards just taking the unit out and putting in a conventional electrical water heater because all of the piping and electrical is already there for it. Any body have some knowledge to share? Thanks guys.
