Proper sized heating unit?
I'm in the middle of an addition/renovation adding 1500 sq. ft. to my current 1500 (all single floor) in WNY. I will be removing my forced air unit and replacing with radiant heat throughout. Addition is 3/4 slab with a 288 sq ft. basement connected to my current full basement. My contractor has recommended a Peerless Purefire 4 (210,00 B.T.U.) unit. Seems a wee bit large to me... I haven't had a heat loss assessment made.
