KEY COMPONENTS OF BOILERS | Boilers Guide

Boilers are part of a hydronic heating system. Hydronic systems use water to transfer heat to a distribution source, like a radiator, to heat a home. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed.

Boiler Information

This hard shell is called "scale" and is often found on the outside of the fire tubes or the inside of water tubes. Scale insulates the heating surfaces reducing the ability of the fire tubes to transfer heat from the hot combustion to the boiler water. High stack temperatures or ruptured tubes are common problems related to scale build up.
