The majority of U.S. residential homes are heated with either furnaces or boilers. Furnaces raise the temperature of air and distribute the heated air through the house using air ducts. Boilers heat water, and create either hot water or steam for heating system. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers function at a higher temperature than hot water boilers, and are essentially less efficient, but high-efficiency models of most types of furnaces and boilers are available today on the market. To find out more about furnaces, boilers along with types of residential home heating systems and technologies, take a look at the Energy Saver 101 Infographic on home heating below.
