Types of Boilers - A Thomas Buying Guide

Less commonly used today are coal fired boilers, which use coal as a fuel. In the case of combustible fossil fuels, the oil or natural gas is ignited to generate a flame which results in the heating of boiler tubes or heat exchangers. Electric boilers use Joule heating to produce heat from an electrical current flowing through resistive elements.
