My experience is that the water never gets hot enough. It's probably ok for a small house but anything over 1500 SF is a problem. I had one installed a few years back in a house I no longer have and the water was never really hot. Maybe the technology has improved since then but I don't want another.
It was undersized then or your pipes were uninsulated and it was losing heat.
Nope, it was a new Centex home and everything was well made. Never did really get hot and it may be because it was one of the first models.
It was adjustable but just never got hot. It was warm but never really reached the hot temperature one would expect. I don't know what the newer models are like but this one just never heated up. The guy who bought my house actually removed it and put a hot water heater back in it's place.
