Converting from steam to hot water heat - Heating Help

Jun 18, 2014 · Convert that radiator to hot water and you're only going to get about 150 Btuh out of that same square foot of radiation. So, for instance, if you have a five-tube, 26" high, 10-section, cast-iron radiator running on steam, it will emit 8,400 Btuh. Convert the system to 180- degree hot water and you'll get only 5,250 Btuh out of that radiator.

Because this "express riser" is very large, it offers less frictional resistance to the water. As a result, the hot water moves more quickly from the boiler to the radiators than it would in the upfeed system. Another plus is the way the cooler water pulls the hot water through the radiators as it falls down the return risers.
