I have a one pipe steam heat system in my current remodel. However, there is an addition on the back of the house that was put on a slab where the only heat now is from two vented wall units. They are of decent quality but they are an eyesore and I would ideally like to get rid of them.
My question, is it possible to tap one of the current steam lines from the main house and run a new radiator into the addition?
The good news is that everything is easily accessible in the main basement and the actual run for the new line would only be about 7 feet.
I know that there are pitch issues of the one pipe system but most importantly I wanted to see if this is even possible.
I will leave this task for a qualified plumber but I wanted to see if I should even waste my time.
