C orrectly Sizing a Steam Boiler-What do I need to know?. The correct selection of a steam boiler output is critical to its operation, efficiency and performance. If undersized for the system load, then steam pressure will rapidly decrease thus causing the boiler to collapse its steam space, in turn causing low water alarms and ultimately burner lockout.

6/23/2014 · The boiler needs to be able to be constantly filling the system with steam (blowing up the balloon) in order for the system to remain balanced when using radiator vent sizing to balance the system. This goes back to the way we can tame oversized radiators by limiting the air venting.
The firebox boiler uses similar tube attachment techniques as the firetube boiler. Its combustion chamber is not round, like the firetube’s cylindrical furnace. The firebox boiler is typically manufactured to low pressure steam or hot water applications. The firebox boiler is a compact, economical unit and serves as a good fit for
A good rule of thumb is to go by the number of radiators the boiler will be responsible for heating. For example a small property with fewer than ten radiators should find the smallest size boiler is adequate.
