Boilers are water heaters with a specific purpose. They act as a heating system, (called hydronic) by carrying hot water through an arrangement of radiators or other similar devices -including plastic tubing for radiant floor heating. The heated water gives off heat. When the water cools down, it is returned to the boiler. Here it is reheated and the process repeats itself. A pump moves the water through the system. Controls include thermostats, aquastats and valves for regulation of both circulation and water temperature. Other energy-saving devices may be added to improve the boiler’s operation. Boilers utilize various types of fuel to heat the water. Usually, it is natural gas or oil. However, electricity or even wood pellets can also be used.
