Air Source Heat pumps absorb heat from the outside to heat the inside of buildings. There are 2 types:
- Air to Air Heating which heats air to heat the building.
- Air to Water Heating which heats water to provide heating via radiators and underfloor heating systems.
The system is electrically powered and produces 5kW of heating for every 1kW of electricity, making it a very efficient and cost effective system.
How it works
The Air Source Heat Pump works in a similar way to a fridge, by extracting heat from outside and using it to heat air or water. An air source pump has three main parts:
- The evaporator coil absorbs heat from the outside air;
- The compressor pumps the refridgerant through the heat pump and compresses the gaseous refridgerant to the temperature needed for the heat distribution circuit;
- The condenser transfers the heat from the refridgerant to the air or water.
Air Source heat pumps present an advantage over ground source heat pumps because they require less space to install. Instead of requiring the installation of buried underground coils, air source systems can be fitted using much less space and are therefore, more suited for an urban home.
Sanctuary Housing Group projects
Sanctuary Housing is building a block of 75 apartments at Jetty Marsh, Newton Abbott .
We are installing the NIBE air source heat pump, installation of a NIBE air source heat pump can lead to the energy consumption for heating being reduced by up to 50%, in comparison to conventional heating systems.
