High Efficiency Boiler Combustion Test | US Boiler Report

Dec 17, 2018· For instance, the K2 condensing boiler has a high fire and low fire O 2 target of 4.9%. This means that the low fire O 2 should be 4.9% or a few tenths higher. I would suggest adjusting the K2 boiler’s low fire O 2 to 5.0 – 5.2%. REMEMBER: Be patient. Very little air is moving through the boiler during low fire.

boilers – operate at extremely high efficiencies with lower flue gas temperatures. This results in a plume of water vapour being visible at the flue terminal when the burner is operating. This pluming is condensation – rather like your breath on a cold day. This is a perfectly normal condition with high efficiency and condensing boilers.

what size boiler is needed per square foot of a house

What Size Boiler Is Needed Per Square Foot of a House

Boiler size describes the heat output of a boiler in energy units, not the physical size of the boiler. Manufacturers measure boiler output in British thermal units (BTUs) per hour or boiler horsepower (BHP). BHP measurements usually only apply to very powerful and large capacity boilers, since one BHP equals 33,475 BTUs per hour.
