    Boiler (power generation) - Wikipedia

    A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

    How Does My Home Heating Work? - Types of Home Heating

    Electric resistance heating is 100% energy efficient because all the electricity is converted to heat. And since the heating elements in an electric furnace are in direct contact with the air, the air heats up very quickly. This makes them very efficient but expensive to operate during extended cold weather. Other Types of Forced Air Systems

    Boiler vs. Furnace Energy Efficiency | Constellation

    Nov 11, 2016 · Energy efficiency in boilers and furnaces is measured the same way — by annual fuel utilization efficiency (AFUE). A unit that has an AFUE of, say 70, converts 70% of its fuel to heat. The other 30% is lost. The federal government dictates that gas- and oil-powered furnaces can’t have an AFUE rating of lower than 78%.

    Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. 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.

    For example, a gas furnace with an AFUE of 80 percent will convert 80 percent of the energy in the gas to heat while the other 20 percent is lost through the exhaust or leakage. Higher AFUE numbers translate to higher furnace efficiency, with AFUE 90 percent and above indicating a high-efficiency system.
