 A heat pump is simply a device for absorbing heat from one place and transporting it to another. Heat pumps can be used to remove unwanted heat (e.g. a fridge or air conditioning unit) or to transport heat to where it is needed. A heat pump is simply a device for absorbing heat from one place and transporting it to another.

 Since the heat comes from a renewable source (the sun), heat pumps can help reduce fossil fuel consumption and thus reduce CO2 and other emissions. It must be remembered though, that heat pumps require a reliable electricity supply which may itself come from a non-renewable source. Given that mains electricity is far greener than it was, the saving in CO2 can be quite dramatic. Modern efficient heat pumps can produce enough heat for any household, including hot water. For every 3-4 kW of heat output produced, 1kW of electricity is consumed for the pump and compressor. This is sometimes expressed as being 300-400% efficient, or having a coefficient of performance (CoP) of 3-4. Since the heat comes from a renewable source (the sun), heat pumps can help reduce fossil fuel consumption and thus reduce CO2 and other emissions.
