I plan on starting to renovate my attic in the next week and heat it with the old cast iron rads as in the rest of my house. But I am wondering if I need to worry about the size of boiler that I have to support the expansion?
I want to add three rads. The house is about 1800 sq' (two floors) and I will be adding about another 500 sq' to the attic. There are currently 10 rads in the house. I believe currently this is divided into two runs. Do I need to worry about which run I add to?
The boiler is a Hydrotherm, model HC1000, serial # CFC1510, Input 100,000 - 90,000, Output 80,000 - 72,000, Net rating 69,000.
One last question, next year I would like to add radiant floor heating to the underside of the joists in the laundry room where their is a tile floor. Can I tie this into the boiler system?
Any input / advise would be greatly appreciated, Thanks
