Air Source Heat Pumps

Ecodan® air source heat pumps are at the cutting edge of low-energy performance and have the potential to reduce a home’s CO2 emissions by up to 50%*.

By simply using a Mitsubishi Electric Ecodan air source heat pump to provide domestic space heating and hot water, it is possible to greatly reduce CO2 emissions.

Using proven heat pump technology widely used in the heating and cooling industry, Ecodan upgrades naturally occurring energy from the air and uses this to provide domestic space heating and hot water. Heat pump technology has been used around the world for decades and Mitsubishi Electric have developed this technology for domestic application to produce Ecodan – one of the most advanced, efficient heating systems available today.

The Boiler Upgrade Scheme will launch in April 2022 to help homeowners and small business owners in England and Wales afford the upfront costs of heat pumps and biomass boilers.

*These savings are based on a 4 bedroom house of standard construction built in 2000. The Ecodan replaced an 80% efficient A rated gas boiler.

Like all new technologies, air source heat pumps are an investment in the future. Developers, housebuilders and homeowners want to be assured that the technology they purchase today will be relevant and useful for many years to come. Mitsubishi Electric’s Ecodan air source heat pump has been designed with the future very much in mind.

Over the last few years Mitsubishi Electric has been recording real world performance data on the Ecodan air source heat pump. The Ecodan units listed on their performance website have been installed in typical domestic dwellings. You can view their live comparision website for the monthly running costs, CO2 emissions, and energy consumption of the Ecodan unit versus Gas and Oil..

What makes Ecodan® unique? – Inverter-driven technology

At the heart of Ecodan is a modern, inverter-driven heat pump compressor which converts free energy from the air and upgrades it to higher temperatures suitable for heating. The inverter control regulates the system so that heat output modulates to match the exact capacity required, meaning the heat pump will only consume the exact energy needed at any given time and thus increase efficiency further.

The performance characteristics of Ecodan® :

  • Low starting current – All Ecodan units operate on a standard single phase power supply and have a low starting current of 5 amps, which reduces power requirement further still. In addition a 3-phase option is available on the 14kW unit.
  • Low noise levels – Crucial to residential applications, the Ecodan range offers some of the lowest noise levels available.
  • Easy to install – The Ecodan heat pump is a self contained unit which only requires water and a single phase power supply.
  • Highest efficiency – With the UK’s ambient temperatures, Ecodan is perfectly designed to operate at optimum performance throughout the year. Ecodan can generate hot water up to 60°C, it also has the ability to operate in the unlikely event of the outside temperature plummeting to -20°C.

Case Studies

Case Study1 – Eco-friendly house, France (PDF 2.2MB)

Featured on Channel 4’s Grand Designs, this unique family home in rural France has been built using the most eco-friendly products and materials available today. Playing a major role in helping to maximise this new home’s energy efficiency is an Ecodan air source heat pump from Mitsubishi Electric.

Having decided that they’d like to live a more ecological way of life, this young family chose to leave their home in Sheffield to embark on a moreidyllic lifestyle in France. They wanted their home to reflect their views, whilst saving them money and be kinder to the environment. In line with their new way of life, they built an eco-friendly house that needed a heating system capable of delivering the lowest running costs and carbon emissions. Advanced, low carbon heating from Ecodan proved the ideal match.

The 8.5kW Ecodan unit sits on a covered terrace and supplies heating to the whole of the ground floor via the underfloor heating system – significantlyreducing carbon emissions and running costs. So impressed are the family with the efficiency and reliability of Ecodan, they’re now considering using Ecodan to provide their hot water to supplement the solar thermal system and guarantee a continuous supply, whatever the weather.

Installation Summary :

  • This unique, straw bale house has been built by the Sampson family in the Lot region of France, near Martel.
  • An 8.5kW Ecodan currently provides underfloor heating for the 4-bedroomed home, with hot water provided by a solar thermal system.
  • The family are now adapting the Ecodan unit to top up the hot water on the solar thermal system.
  • The Ecodan unit plays a major role in helping maximise the home’s energy efficiency and is in keeping with the homeowners’ desire to use the most eco-friendly products and materials available today.
