2. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Air-to-air heat pumps provide hot or cold air directly to rooms, but do not usually provide hot water. Air-to-water heat pumps use radiators or underfloor heating to heat a whole house and are often also used to provide domestic hot water. An ASHP can typically gain 4 kWh thermal energy from 1 kWh electric energy.

3. Air conditioning - Wikipedia

   en.wikipedia.org/wiki/Air_conditioning

   The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]

   In the United States, the efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute, a trade association, in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

5. 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.

6. Geothermal heating - Wikipedia

   en.wikipedia.org/wiki/Geothermal_heating

   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 pump draws heat from the air (colder outside air) and thus requires more energy.

   LG was also an official supplier to Virgin Racing and Lotus Racing team, plus engine manufacturer Cosworth from 2010 to 2012. [100] LG also sponsors London Fashion Week and the LG Arena in Birmingham. [101] During the period 2001–2003, LG sponsored the snooker Grand Prix. During these years the tournament was known as the LG Cup. In 2008, LG ...
