Mitsubishi Air-to-Water Heat Pumps

Residential Air Source Heat Pumps

Upgrade your home’s heating system to the reliable and sustainable Mitsubishi A2W Heat Pumps. Designed as a renewable, low carbon alternative, these air source heat pumps offer highly efficient space heating and hot water solutions all year round. From small flats to large detached houses, and from office blocks to schools, the A2W Heat Pumps are the perfect choice for a greener and more cost-effective heating system.

How an Ecodan System Works:

Outdoor Unit: The Heat pumps require only electricity and water connections. The outdoor unit is easy to install and can be discreetly placed outside your home or in your garden. It harnesses freely available heat energy from the air and transfers it to your home, providing hot water and heating for radiators and/or underfloor heating

Hot Water Cylinder: Experience a continuous supply of hot water through our dedicated hot water cylinder, similar to a standard boiler. These cylinders are designed to integrate seamlessly with the outdoor unit, and in some cases, they can also work with your existing hot water cylinder.

Energy Efficient Control: Take control of your system’s performance with a range of control options. Choose our advanced wireless controller for easy management, including a holiday mode. You can also download the web-enabled MELCloud controller app on any smart device to monitor and control your system remotely.
