Benefits of the outside air as a heat source

  • Can be utilised all year round between +35°C and -25°C
  • Always available and inexhaustible source of heat
  • No requirement for the cost and land area of ground collectors
  • Ideal for new build or retro fit applications, especially where space is limited
  • Can be used for heating, cooling, domestic hot water and swimming pools

Optional outdoor or indoor installation

Air source heat pumps are suitable for either outdoor or indoor installation.  Outdoor air source heat pumps are constructed from robust, powder-coated metal casings to provide year round protection against the elements. The heat pump is connected to the indoor heating system simply by laying two heat insulated pipes and the electric connection cables under the ground.

In some instances it may not be desirable for the heat pump to be installed in the garden. Indoor air source heat pumps offer a practical alternative and can be installed for example in a garage, basement or utility room. The heat pump is connected to the outside air via air ducts.

Air to water heat pumps for outdoor installation

  • The heat source is easy to tap
  • The weatherproof heat pump is installed on a sturdy concrete foundation
  • The water pipes and electric cables are securely laid under ground

How it works

An ASHP works a bit like a refrigerator in reverse. The process consists of an evaporator, a compressor and a condenser. It absorbs heat from the outside air and the heat pump compressor then increases the temperature of that heat further to create useful heat.

There are two main types of ASHP:

  1. Air-to-water systems take heat from the outside air and feed it into your wet central heating system. As the heat produced is cooler than that from a conventional boiler, you may need to install larger radiators or undefloor heating in your home to make the most of it.
  2. Air-to-air systems take heat from the outside air and feed it into your home through fans. This type of system cannot produce hot water.

In the summer, the ASHP can be operated in reverse, like an air-conditioning unit, to provide cool air for your home.
