    Yes please

    more specific questions!  One could write a book on the topic...



    One might note, though, that there is nothing special about combination systems; the one pipe areas will behave that way, and two pipe areas the way other two pipe systems run...

    I don,t have

    A specific question. I just wanted to find some more reading material.

    For example we had a job recently which had 1 1 pipe rad on a 2 pipe system we added a return and trap to make it 2 pipe. It would have been alot easier to leave it 1 pipe.

    We have no control over pressure or venting as it is an apartment building and I was afraid of spitting vent onto a wood floor. LIABALITY

    Burnham Heating Helper

    Hi- I'm not a pro, but one of the most useful books I have found for quick reference is the Burnham Heating Helper. It's really handy to check the specs and capacities when you run across odd ball piping which you typically find with mixed one and two pipe systems.

    If you don't already have a copy here is the link:
