Cast Iron Radiators

I just did my cousin's new house a few years ago. We used cast iron rads and cast iron baseboard and some radiant in-floor.
We used TRV's and I "home runned" all of the radiators to manifolds with pex tubing. The house is on outdoor reset, very, very comfortable!

cast iron radiators
I am installing a new system in an older house. The owner wants standing castiron radiators. Should I install a one pipe system with moniflow tees or is there a better way? It is a single story house with the radiators above the heating mains.0 -
I'm a bit confused. What present form of heat?
Frankly, were I installing a new system using cast iron radiators I would not consider anything except two-pipe with TRVs.
In my area, both one-pipe and two-pipe systems with iron rads are fairly common. One-pipe is almost always in wide-open commercial space while two-pipe is almost always in homes. The only one-pipe residential system I recall was in a smaller home with an unusually "open" floorplan for the day.
If a condensing/modulating boiler is to be used I would not--ever--consider a new one-pipe system using iron rads.0 -
ditto....
I would home run the to manafolds too. I did the same thing w/ my own home w/ panel rads. The pex was easily snaked up walls...kpc0 -
Hi Bill I like your idea about using manifolds to distribute water to the radiators. I cannot use pex tubing because I am an old timer & it is my house. I will have 7 radiators thus will have 14 1/2 lines coming back to the manifolds. I do not know what you mean by TRV's could you explain.0
