Heat Loss Calculator
I have just purchased a house in Santa Cruz, CA. It is about 2400 sq ft, two story and was built in 1975. It has Hydronic baseboard heat. The construction is pretty typical for that era. I have scheduled a blower door test to see what my starting place is. I plan extensive remodel and energy upgrade over the next year.
I have prepared a detailed floor plan and find 96 feet of Slantfin baseboards. Using Slantfin specs, I get about 550 to 600 btu per foot of baseboard which adds up to at most, 60,000 byu's. There is a 200K BTU boiler in the basement. Does this make sense?
I would like to do a thorough heat loss calculation but I can only find very expensive software or one free program (from Slantfin) that will only run on my iPhone. I find it very tedious to enter this much data into an iPhone.
After doing all the bath and kitchen remodeling, replacing the windows and upgrading the crawlspace and attic sealing and insulation I plan on putting in a new condensing, modulating boiler so I would like to size it properly.
