Well, we installed our vista flame 170 today and we love it. This thing is amazing! It was a bit of a pain getting it in the house because of the weight, but we got it done. I also had to change all the exhaust over to 4’’ since the old Breckwell was 3†exhaust. Anyway, it’s running now and my 2500 sqft house is nice and toasty. Even upstairs. Amazing. Thanks all for the help in making this decision. I’ll post some pictures this weekend. Oh, my biggest concern was the noise this would make and it’s not bad at all. The dishwasher bothers me more than the vf170.
