Air Source Heat Pumps

Approved Ecodan Installer - Grants Available

You can only buy Ecodan through an Approved Ecodan Installer (AEI). This helps to ensure that your system is optimised to suit your individual property and consistently delivers the highest standards of performance.

AEI’s are independent contractors and plumbers who have demonstrated that they are appropriately qualified, have attended the Mitsubishi Electric Ecodan training day and have met the qualifying criteria.

Whether you live in a small flat, or a large detached house, Ecodan can help to reduce running costs, lower CO2 emissions (*) and offers reliable, sustainable heating and hot water all year round for the overwhelming majority of homes.

* In independent tests carried out by the Building Research Establishment, BRE, Ecodan was found to reduce emissions by 50% and running costs by 30% in comparison to a modern gas boiler.

Ecodan does cost more than a gas boiler to purchase but with the Microgeneration Certification Scheme (MCS) grants of up to £900 against installation costs are available. Please see the 'Grants & Schemes Page' for more details (note the 3-phase 14kW model is not MCS accredited). In addition, the reduction in energy bills compared to gas, mean that the system can pay for itself within 2 – 3 years. In areas off the gas network, Ecodan can offer significant reductions in installation and running costs over oil.

Maintenance on an Ecodan system is easier than gas as well, and with a professionally maintained Ecodan heat pump unit offering an average lifespan of 15 – 20 years, you’ll save on annual maintenance costs too.

Ecodan offers hope for hard-pressed households everywhere, with a system to suit almost any property from the 1970s (*), whether this is a small flat or a large detached house. Older properties that have been thermally upgraded can also benefit from this low carbon alternative to traditional domestic hot water systems.

* To work at maximum efficiency, a home needs to have thermal insulation levels equivalent to the 2000 Building Regulations.

Ecodan Explained

Many have heard of ground source heat pumps and the high efficiency levels they can offer but few have realised that air source heat pumps can also offer significantly higher levels of efficiency when compared to traditional methods of heating our homes.

Air source heat pumps are much easier to install than ground source so they are more suitable for a wide variety of properties from flats to detached houses.

The Ecodan air source heat pump system consists of an external box which is fitted to your outside wall. It harvests renewable, low grade energy from the outdoor air and upgrades this into useful heat to supply a home with hot water and heating. For every 1kW of electricity fed into Ecodan, you will get at least 3kW of heating energy.

The outdoor unit is a bit like your fridge in that it has a circuit of factory-sealed copper piping containing ozone-friendly refrigerant, which is continually compressed and expanded to extract the free, renewable energy from the air.

Your fridge extracts heat from the box inside (to keep food cold) and rejects it at the back. The air source heat pump works a bit like this but in reverse in that it extracts heat from the outdoor air and upgrades it to heat up your hot water supply.

It can work efficiently all year round even if the outdoor temperature should drop to -15ºC.

The Ecodan range of air source heat pump systems have been developed by Mitsubishi Electric specifically for the UK and bring advanced, inverter-driven technology refined in the commercial heating sector to your home.

The Ecodan Range

Our comprehensive Ecodan range is designed to suit a wide number of applications, from a small flat to a six bedroom house and will cater for the varying requirements of both new build and existing homes.

W50 (PUHZ-W50VHA)
The smallest capacity unit in our Ecodan range is the W50 which is 5kW and is perfect for use in new build applications due to their modern day thermal efficiencies. Able to work at variable capacities between 1.5kW and 5.2kW the W50 is ideal for many applications ranging from smaller existing homes or flats to medium sized newly built homes.

W85 (PUHZ-W85VHA)
Currently the popular unit in our Ecodan range is the W85 which is proving ideal for use in both newly built homes and existing homes too. Able to work at variable capacities between 3kW and 9kW the W85 offers the widest scope to cater for the majority of applications

HW140 (PUHZ-HW140VHA)
Catering for applications with a greater demand for a more powerful unit is the HW140. With the potential to operate between 5kW and 14kW, our most powerful unit is perfectly suited to provide effective heating and hot water for larger, existing homes that do not benefit from the thermal efficiencies of today's homes. This unit is also available as a 3-phase option, please note the 3-phase model is not MCS accredited.
