I have a Bell & Gossett PL36 pump. I have a total of 360' of 1" pipe from the boiler outside to the furnace and through the DHW. I already have 240' of 1/2" Pex to the basement floor and stapled between the floor joists. I was wondering if this is too much for the pump. I ask cause I have no idea how to measure head pressure and whatever needs to be figured. I also can't find figures that I could understand. Thanks in advance. The reason I ask is cause I'd like to add just a little bit more cause the ceramic tile floor is so cold. Thanks in advance.
