Boiler pressure is a measurement of the pressure of the hot water passing through the central heating system. Should the boiler pressure drop too low then the central heating will fail to work. Your boiler will feature a pressure gauge that can be used to read the boiler pressure. If the needle is anywhere below 1 then the pressure is too low.Learn More
Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.Learn More
