I have an old building with a boiler and the old steam radiators (most of which are disconnected). The boiler has not been used in 20 plus years. What would be a good low cost replacement system. Could I re-use the old boiler?
Thank you for your response. It is along the lines of what I had thought. I know this site/forum is for homes, but my "project" is a large building (3 floors - basement, main, upper) and about 10K square feet. Do you think that a radiant floor system would be effective in a large building? How much space can you heat with a "tankles" boiler/heater? Thank you in advance.
