How heat pump technology works

These heating systems require only a small amount of electricity to upgrade and move heat from one location to another. The heat is upgraded to a higher temperature using the refrigerant cycle and is then used to deliver efficient heat to any building via a ducted air or wet system.

  1. Compression: Refrigerant in its vapour state is compressed, heating the vapour to temperatures of 75ºC to 80ºC.
  2. Condensing: The hot pressurised refrigerant vapour is then passed through a heat exchanger. The vapour condenses into a liquid and the heat generated by this process is transferred to heat the air and/or water, to be used within the building.
  3. Expansion: The cooled refrigerant liquid is then passed through an expansion valve which reduces the pressure on the refrigerant allowing it to return to its normal state.
  4. Evaporation: Liquid refrigerant is passed through a second heat exchanger. Because refrigerant has a very low boiling point, as low as -50ºC, the refrigerant evaporates, absorbing heat energy from the surrounding environment - air, water or the ground.

Air to Water heat pump systems

Renewable energy is extracted from the outdoor air and indoor heat is delivered by using a wet system, such as radiators or an underfloor system.

Each indoor heat pump boiler is rated at 25kW and is available as a single unit, as a 50kW twin module, or a 75kW triple module. These modules can combine to make a single system of up to 200kW, multiples of which can then be installed to suit larger commercial heating applications.

Ground to water heat pump systems

Renewable energy is extracted from the ground or water and indoor heat is delivered using a wet system such as via radiators or an underfloor system.

Each indoor heat pump boiler is rated at 25kW and is available as a single unit, or as a pre-mounted and pre-piped 50kW twin module, comprising two 25kW indoor heat pump units and two 25kW heat pump boilers.

Air Source Heat Pumps

Air source heat pumps (ASHP) extract heat from the outside air. This is then used to deliver heat to the building via a ducted air or a wet system.

Recognised as a renewable technology, air source heat pump outdoor units are located on the building roof or on the ground. Operating at outside temperatures as low as -20°C, air source heat pumps are ideal for use in any UK commercial property.
