What is the correct temp setting for a hot water boiler

Water from the boiler is injected into the radiator circuit at a rate designed to precisely maintain the radiator temperature relative to the outdoors. It can vary from 70 degrees (room temperature) up to 180F if you need it. The boiler is maintained at a different scale, the 180 to 140 range because you have to. Oh well.

Improve Your Boilers Combustion Efficiency

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

Jan 15, 2017 · Answer Wiki. Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls. I am talking about big boilers of 800MW (super critical) capacity. Output main steam temperature ranges from 550 to 570 deg.
