Hello all, help greatly appreciated. I am about to tackle two heating jobs in the house but have gotten way conflicting advice from local supply house. Hoping to get help and unbiased info here. House in northeast. Room is new construction with 2 x 6 walls insulated, with 2 x 10 ceiling insulated as well.
First project is as follows.
Second story addition room is 25' x 36', so 3 walls to the environment (25' twice). Ceiling height is 8' center angling down to 4' knee wall so not full height. Room is approx 900 total sq feet, including 91 square feet of windows. Total round trip run from boiler start to finish is 426 feet counting fittings, valves etc.
Wanted to zone as one loop. Told both yes and no.
Can't figure out footage of baseboard room needs, but easiest way for me to install is complete perimeter of room of approx. 86 - 100 feet depending upon install.
Advised circulator Taco 0015 $125 up to Bell & Gossett PD37T 3phase at $1,750. Don't have 3 phase in house, so not an option anyway.
Wanted to run black pipe from boiler 1 - 1 1/4 up to radiator. Told I couldn't mix with copper pipe. Don't know why since black pipe at boiler end anyway. Is there a drawback to running black pipe? Wanted to get as much hot water up to radiator based upon distance from boiler. Comments??
Any help in clarifying job greatly appreciated.
