I have an existing hot-water heating system in my house (oil and wood fired). The pipes are filled with antifreeze because some of the piping goes through unheated crawl space. I would like to add a couple of radiators to the system.
I know that I'll have to drain the antifreeze (at least partially) in order to sweat the tees in. There are several valves along the system to do that. My question is, how would I add the antifreeze back into the system once I am done? The valves are up against the cellar ceiling. Would I have to use a transfer pump? How do I purge the air?
Thanks in advance for your help.
