KEY COMPONENTS OF BOILERS | Boilers Guide

The boiler is the part of the system that heats the water to be distributed. The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls. Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler. Key Components of Boilers

The tankless coil is a more efficient heat exchanger than a homemade side-arm is. With a tankless coil, the recovery rate for the storage tank is faster. If a new boiler is not needed, buy or make a boiler side-arm. A side-arm is similar to a shell-and-tube heat exchanger and gets installed on the boiler's supply pipe (see Figures 2 and 3).

The Role, and Potential Danger, of a Heat Exchanger

Essentially, the heat exchanger is where the furnace heats the air. The Danger of a Cracked Heat Exchanger. A damaged heat exchanger is a problem as it enables the exhaust fumes inside the exchanger to leak into your indoor air. The most toxic of these exhaust fumes is carbon monoxide, which can cause severe health problems.
