In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Have both single and double radiators, now what?
I bought a fairly large house with 10 radiators. 8 of them are one pipe and the other two (one directly above the other) are two pipe.
I bought your books because no one around here knows much about steam heat, and I've never had anything other than forced hot air before this house. Much of the insulation is missing and I'm in the process of replacing it.
My question is this: what do I do about having both types of radiators in the same system?
