Boilers can be used to either supply hot water (hydronic systems) or steam for heating the home and can be fueled by electricity, oil, gas, wood or coal. Steam boilers were popularly used in the early 20th century. For simplicity, the components listed in this article are exclusively for steam boilers. Read More

Hot water heating systems are built around the premise of radiant heat. Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems. Read More

Hot water boilers don't need cleaning very often. A thorough cleaning at the time the system is installed is necessary, but after that it shouldn't be necessary to do so unless the water becomes obviously discolored or visible scale starts to form on the outside of pipes, valves or fittings.

Boilers use a fuel source: oil, gas, propane, or electricity to heat water to just below a boil between 160 degrees and 180 degrees. This heated water is sent through pipes throughout the building into radiators built in all of the rooms. As the hot water passes through the pipes in the radiators the pipes get warmer and emit the extra heat into the room. Now spent of its heat, the cooled water returns to the boiler to begin the cycle again. Read More
