I don’t know what to tell you. We ran the heat at 65 and had to reset to 60. Still too hot. The water in the lines stayed at 80 for 4 days and is at 60 now after 9 days. The extra insulation and artic foil really did the job. The other day it was 85 outside and 62 inside and holding. What a system. I will take pics and send them to you. Also, the condensing boiler has only fired up 2 or three times and now won’t until the fall. So I will let you know then. If you need some small testimonial, let me know. Thanks for everything.
