Hydronic help

BrianD

I live in a converted barn with a new concrete floor with a hydronic floor heating system. 1200 square feet. Best thing I ever did. In the winter , even when its below zero outside, it never gets below 55 degrees upstairs. I have R19 wall insulation and 4 inches of closed cell foam on the roof. Because of the exposed woodwork on the first floor I am only able to put hydronic floor heat on one third of the upstairs. If I do that and add some wall hydronics, do you think it would be sufficient to heat the entire upstairs?

I would recommend downloading the Slantfin heat loss calculator and do the math to figure out what your heat loss is, and see what you can get out of your planned wall panels. There is no other good way to answer this question except for guesswork.

Anything is possible, it's just a matter of how much you want to spend and how much heat you need. The heat loss is going to be a tough gig, but for only a 15-20 degree rise across 1200 sq ft the heat load is pretty minimal. I'd say you're talking 6,000 BTU or less assuming 5-6 windows and 8ft sidewalls. A small amount of baseboard or panel rads, even radiant walls or ceiling should do the trick pretty easily. The first step is a proper heat loss calc though
