Hot water Radiator Risers
Posted by Joseph Templer on December 27, 2001 at 10:53:44:
I am in the process of building a three story house with a hot water radiator heating system. I am curious what size supply riser I need to feed all three stories. The boiler will be in the cellar and there will be three risers, one for each floor. Each floor is approx 10' high with a total of 1500 sqf per floor. What size riser pipes should I use? What size pipe should inter-connect each riser on every floor? What size feed should I use on each floor?

Any help or links for correct sizing or caluactions would be appreciated!!
