Hi, I am hoping to get some guidence dialing in a hydronic baseboard heating system I have made some modifications to, in the process of rehabbing my house.
Specifically, I think I need to resize my circulator pump, due to the modifications.
The home was built in 1970, and previously had a simple, but relatively new (2005) cast iron boiler, heating a bunch of copper fin tube convectors.
I have done a bunch of research on this site, and others, over the last few years and decided to get a bunch of old cast iron baseboard radiators and overhaul them.
I disassembled them all, had them sandblasted and powder coated, and reassembled them all, and currently have them plumbed in. I also added a bigger expansion tank to accommodate for the larger volume of water in the system. Everything is leak free, and the heat works well, except for that I get some water schwooshing noises, seeming to be from one radiator in particular.
I don't know for the name of the type of loop the system is, but I'll try to explain it.
The output from the boiler (which is located 3/4 way towards north end of my simple ranch house) goes down into my crawl space, and runs 1" copper all the way to my south wall, where it than tee's off into 3/4" pipe. That 3/4" copper than runs along the east and west sides of my house, with all the radiators plumbed in series. The east and west runs than connect back at the boiler return, teeing back into 1" pipe back into the boiler.
I am currently running a taco 007 pump (because it's what was previously there) but I'm thinking it may not be the ideal pump for the way the system is currently setup.
Can anyone offer advise on how to calculate the ideal pump for this setup?
