Boilers

Boilers are fuel-burning appliances that produce either hot water or steam. The resulting steam or hot water is circulated through piping for heating or process uses. Proper maintenance and operation of boiler systems is important to ensure efficiency and reliability. The source of heat for a boiler is typically the combustion of fuels such as natural gas, coal, oil, or wood.
