Hot-Water Radiators 101
In hot-water radiators, a pressure-reducing valve between the city water and your hot-water heating system keeps it filled all the time. Most two-story homes need 12-psi pressure, and that’s the factory setting of the valve.
Steam Radiators 101
If you have steam heat, each of your radiators will have either one or two pipes. All steam radiators take advantage of gravity to get the condensed steam (called “condensate”) back to the boiler. The key to making it all work is to keep the system pressure low.
Converting Radiators
Because two-pipe steam radiators have connections across both the top and bottom of each radiator section, they can be converted to run on hot water. (One-pipe radiators, on the other hand, can’t be converted, primarily because they’re only connected on the bottom.)

Once there, it can block the flow of water, causing some radiators to remain cold.
