  2. 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.

  3. Geothermal power in the United Kingdom - Wikipedia

    en.wikipedia.org/wiki/Geothermal_power_in_the...

    Although the UK is not actively volcanic, [1] a large heat resource is potentially available via shallow geothermal ground source heat pumps, shallow aquifers and deep saline aquifers in the mesozoic basins of the UK. [2] Geothermal energy is plentiful beneath the UK, although it is not readily accessible currently except in specific locations. [3]

  4. Direct exchange geothermal heat pump - Wikipedia

    en.wikipedia.org/wiki/Direct_exchange_geothermal...

    DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

    The number of heat pumps being installed in UK homes and small business jumped 43% last year but is still significantly below targets set by the previous government. There were almost 60,000 ...

  6. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Heat can be extracted from any source, no matter how cold, but a warmer source allows higher efficiency. A ground-source heat pump uses the shallow ground or ground water (typically starting at 10–12 °C or 50–54 °F) as a source of heat, thus taking advantage of its seasonally moderate temperatures. [15] In contrast, an air source heat ...

  7. Renewable heat - Wikipedia

    en.wikipedia.org/wiki/Renewable_heat

    A heat pump with Interseasonal Heat Transfer combines active solar collection to store surplus summer heat in thermal banks [9] with ground-source heat pumps to extract it for space heating in winter. This reduces the "Lift" needed and doubles the CoP of the heat pump because the pump starts with warmth from the thermal bank in place of cold ...

  8. Closed-loop geothermal - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_geothermal

    Scale: Ground source heat pumps are used for small-scale residential heating and cooling and typically produce less than 1 kilowatt of thermal energy. [20] Closed-Loop Geothermal Systems are used for utility-scale commercial and industrial energy production and typically produce greater than 1 megawatt of thermal energy.

  9. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    Air source heat pumps are the most common models, while other types include ground source heat pumps, water source heat pumps and exhaust air heat pumps. [3] Large-scale heat pumps are also used in district heating systems. [4] The efficiency of a heat pump is expressed as a coefficient of performance (COP), or seasonal coefficient of ...
