Steam Heat and Heating Q&A - Natural Handyman

When the water boils, the steam rises into the radiators to heat them. When the steam reaches the cooler radiators, it condenses to water and drains down the pipes back to the boiler, where it is reheated. The pressure release valves are designed to keep the steam moving throughout the system.

4 things to look out for in steam boiler pressure controls

The boiler operating control is set at the desired steam pressure of the boiler. On-off steam systems for comfort heating are usually set for an average of 2 lb. of steam pressure. The operating control is an automatic one that will cycle the boiler between the settings of the pressure control as long as there is a call for heat.

Johnston Boiler Technical Paper in support of 4:1 over 10:1 This paper presents a case where it is more efficient to run a 4:1 in an on-off mode rather than run a 10:1 boiler at 10% fire. The paper assumes that the 4:1 boiler can be shut off for long periods of time, and the 10:1 boiler uses large amounts of excess air at low fire.

Automatic Water Feeder Keeps Putting Water In The Boiler

If unaddressed this can lower the lifespan of a boiler drastically. A steam heat system, when running well, will need very little new water at all. The boiler heats the water to steam, the steam rises to the radiation, the steam condenses back into water over time and then cascades back down to the boiler through the piping.

Starting and Stopping Boiler - Marine Engineering
