In Reply to: Steam Boiler Control Question posted by Mike on December 10, 2007 at 10:50:07:
: I recently replaced my 60 year old steam boiler with a new Weld McLain SGO4 unit.
++ You have the results of the techs not realizing that it takes four times as long to heat a boiler and water four times as much as the new metal and water content of new boilers. Your boiler is MUCH larger than the radiators need, so it overshoots. It is possible the burner tech can reduce the nozzle input of the burner to allow a slower rise.
There is no specific control for the exact purpose you describe; but there are certainly add-on thermostat controls that can sense radiator temperatures to shut the burner off. Local plumbing/heating suppliers carry L6006 controls that can be strapped to a radiator and wired into the thermostat circuit.
