In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have just bought a new ( old) building with steam heat. One of the rooms was an addition over an old porch and did not have a radiator in it. I had a plumber install a new radiator in the room and hook up the pipe in the basement . They installed 3/4 inch to the new radiator, around a 10 ft run with three 90 degree elbows. but all the other ones in the house are 1- 1/4 inch pipe. Except a base board radiator in one room with 2 pipes ( all the other radiators in the house are one pipe. The new radiator won't heat up all the way across the fins only three closest to the intake heat up and the heat won't go all the way across the radiator. I have a new Hoffman adjustable vent on it and and have tried all the different settings. Question is the 3/4 pipe to low of a volume to work with my radiator?
