Environmental technology manufacturer Mitsubishi Electric has launched an incredibly efficient new heating system that harvests and upgrades the energy found naturally in the outdoor air to minimise energy use within our homes and dramatically reduce carbon emissions.

The Ecodan heat pump boiler gathers over 70 per cent of the heat energy it needs from the surrounding air, making it significantly more efficient at providing heating and hot water than modern condensing gas boilers.

Ecodan, which has BRE testing to validate performance, uses a sealed vapour compression cycle similar to a domestic refrigerator to exchange heat (or energy) between the outdoor air and the water supply. Ecodan comes as a simple to install, packaged system that is perfect for use in a variety of house sizes and styles. Ecodan is a new generation air source heat pump boiler (ASHPB) that is specifically designed for the UK’s domestic market and achieves an average of between 10 – 30 per cent reduction in running costs over gas, depending on the age of the gas boiler being replaced.


Significantly quieter and smaller than previous generations of ASHPBs, Ecodan is easy to install, requiring an in/out water and single-phase electrical connection. The company also stresses the need for exacting standards of installation coupled with modern levels of building insulation to ensure the greatest efficiency for each home.

Unlike previous forms of heat pump boiler, Ecodan's carefully developed control system has been specifically designed to provide hot water to either underfloor heating systems or traditional radiators in properties with appropriate levels of thermal insulation.
