How a heat pump works

A heat pump controls the temperature by transferring heat. There are three essential components to a heat pump: the outdoor unit (evaporator), the indoor unit(s) (condenser) and the refrigerant. The refrigerant transfers the heat as it circulates between the outdoor and indoor unit(s).

  • The evaporator extracts energy from the renewable source (air, water, geothermal or solar) by forcing the liquid to transform into a gas.
  • The compressor compresses the gas, which raises its temperature.
  • The condenser exchanges the heat from the gas to the heating system, and the gas returns to a liquid state.
  • The expansion valve lowers the pressure of the refrigerant, which triggers evaporation and the cycle begins all over again.

We simply reverse this cycle to cool your home.

Perfect fit for new builds

Daikin’s air-to-water low temperature heat pumps are the ideal choice for new homes or builds.

When combined with underfloor heating or low temperature radiators, the configuration requires less energy to heat your home. Daikin’s heat pump technology is designed in Europe for our specific needs and climate, air-to-water heat pumps are suitable for all types of climates.

Phil Hurley, Managing Director of @NIBEEnergy, says the infrastructure required for ground source heat pumps should be considered a long-term priority.

The @theCCCuk says its Sixth Carbon Budget is the first detailed route map for a fully decarbonised nation. It calls for a 78% reduction in emissions between 1990 and 2035, bringing forward the UK’s previous 80% target by nearly 15 years.

With an ever-increasing focus on the future options for low carbon heating, Tim Mitchell of @KlimaTherm_UK looks at what's hot in heat pump technology #renewables #cleanenergy
