Boiler Horsepower What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP Boiler Horsepower BHP = (LB/HR*fe)/34.5 Lb/Hr Pounds per Hour BHP = 21500 * 1.08 / 34.5 Fe Factor of Evaporation BHP = 673 Cycle
PVG boilers utilize either a 3 or 4-inch stainless steel vent pipe to direct the flue products out of the building. This eliminates the need to install a liner in an existing chimney - which is often a major expense when replacing an older boiler.
But eight out of ten hot water boilers we install are high-efficiency condensing boilers. With high-mass, cast iron hot water boilers, I never really gave any thought to the quality or treatment of the system fill water. I would drain the system, cut the old boiler loose, connect the new boiler, fill and purge, and be on my way.

The boiler is better able to respond to large loads as the 'low fire' position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on 'low fire', it can immediately respond by increasing the firing rate to 'high fire', for example the purge cycle can be omitted.
