  2. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    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 ]

  3. Renewable Heat Incentive - Wikipedia

    en.wikipedia.org/wiki/Renewable_Heat_Incentive

    The renewable heat technologies which are eligible under the Non-domestic RHI are solar thermal (hot water) panels, ground source heat pumps, water source heat pumps, biomass boilers, and biomethane. The list was extended in April 2014 to include air to water heat pumps and deep geothermal. See table of tariffs [3] for the Non-domestic RHI.

  4. Renewable heat - Wikipedia

    en.wikipedia.org/wiki/Renewable_heat

    Renewable heat is an application of renewable energy referring to the generation of heat from renewable sources; for example, feeding radiators with water warmed by focused solar radiation rather than by a fossil fuel boiler. Renewable heat technologies include renewable biofuels, solar heating, geothermal heating, heat pumps and heat ...

  5. Microgeneration - Wikipedia

    en.wikipedia.org/wiki/Microgeneration

    Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power. Microgeneration technologies include small-scale wind turbines , micro hydro , solar PV systems , microbial fuel cells , ground source heat pumps , and micro ...

  6. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

  7. District heating - Wikipedia

    en.wikipedia.org/wiki/District_heating

    The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria. Animated image showing how district heating works. District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water ...

  8. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    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 ...

  9. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.
