I installed a very similar unit from Travis industries four years ago. Overall I am very impressed with the performance. The thing that I like better about yours is that it is non-cat. Mine has a catalistic combustor that performs great, but it needs to be replaced after just three seasons of burning 24/7 (they say it should last five to ten years). I have learned a lot about prolonging the life of the cat, so I think that I can get more years out of the next one. One of the things that I like about mine is the option to use outside air for heat because that intoduces fresh air into the house in the winter and positively preasurizes the house making it feel warmer (I couldn't tell if yours has that option). Anyway, it looks a well made unit. You will be very happy and the utility company not so happy.
