We bought this early January, as we had a leak in our old system and it was already 15 years old, so it was time for a replacement. Easy to use the dial for temp control. It is silent, our other one was pretty loud when it was on. It has a 5 year warranty, so that gives some piece of mind. Lucky it was on special, as they aren't cheap. So far, so good. I guess we will see how it goes over winter when it gets really cold here, as to how hot the 50 degree setting feels.
