   AFUE = furnace efficiency ≈ 95% for a modern condensing furnace; COP = heat pump coefficient of performance ≈ 3.2 seasonally adjusted for northern US heat pump; EI = emissions intensity of electricity ≈ 200–800 ton(CO 2)/GWh, depending on the region's mix of electric power plants (Coal vs Natural Gas vs Nuclear, Hydro, Wind & Solar)

3. Absorption heat pump - Wikipedia

   en.wikipedia.org/wiki/Absorption_heat_pump

   An absorption heat pump (AHP) is a heat pump driven by thermal energy such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water [1][2] differently from compression heat pumps that are driven by mechanical energy. [citation needed] AHPs are more complex and require larger units compared to compression heat pumps ...

4. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   e. A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. [1] In cold weather, a heat pump can move heat from the cool outdoors to warm a ...

   Here are five key things to consider from the experts at Carrier, a leader in high-technology heating, air-conditioning and refrigeration solutions: 1. Energy Efficiency. Heat pumps are rated by ...

6. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

   Electrical heaters are often used as backup or supplemental heat for heat pump systems. The heat pump gained popularity in the 1950s in Japan and the United States. [14] Heat pumps can extract heat from various sources, such as environmental air, exhaust air from a building, or from the ground. Heat pumps transfer heat from outside the ...
