A highly energy efficient system

Whether you live in a new-build or an existing home, an Ecodan air source heat pump can work on its own or in conjunction with an existing heating system. By eliminating the need for costly fossil fuels like gas and oil, it can help cut your energy bills, lower your carbon footprint and earn quarterly payments from the Government’s Renewable Heat Incentive (RHI) scheme.

Government incentive grants

In addition to low running costs, Ecodan is recognised by government as a renewable energy source because it harvests free energy from the air. This makes it eligible for seven years of payments from the Renewable Heat Incentive (RHI). You can increase these payments further by adding a Metering, Monitoring Service Package (MMSP) making you eligible for an additional £1,610 payment over the seven years RHI period.

Low noise levels

Ecodan is not only highly efficient; it is also one of the quietest units available on the market. An Ecodan renewable heating system is discrete and whisper-quiet, offering flexibility in where you can choose to place it and making it perfect for almost any location.

A future-proof heating solution

Ecodan renewable heating systems are self-contained and versatile, only requiring electricity and water connections. They upgrade freely available heat energy from the air and transfer it to the home to provide hot water and heating for radiators and / or underfloor heating. The Ecodan outdoor unit provides your home with a continuous supply of hot water via a dedicated hot water cylinder. Our hybrid system option also allows it to work in tandem with your existing boiler.

How an Ecodan system works

Ecodan Ambassador George Clarke

The way we design, build, heat, power and recycle our homes needs to change and change quickly and renewable heating is an important part of our future. I’m therefore delighted to associate myself with the market-leading brand of heat pumps which are built here in the UK and which can help reduce energy bills and lower emissions for almost any home

Types of Ecodan

Ecodan air source heat pumps use 1kW of electrical energy input and take 2.2kW of low temperature renewable heat energy from the air, producing a high efficient 3.2kW heat energy output. This heats refrigerant in the system which in turn heats water for domestic hot water and space heating.

Is Ecodan right for you?

As the UK strives to meet its carbon reduction targets, renewable heating systems like Ecodan air source heat pumps have been recognised as an important part of the solution. This is why the Government is encouraging the installation of heat pumps as the low carbon alternative to gas, oil and LGP heating.

Ecodan renewable heating systems allow Housing Associations to comply with regulations and legislations and are simpler to maintain than gas, removing the need for gas safety certificates. The system can help reduce a property's carbon footprint, simplify maintenance regimes and help tenants combat fuel poverty by reducing household running costs.

With an Ecodan air source heat pump there is no need for groundwork preparations such as pipework. The Ecodan system can be easily mounted outside of the home at a convenient location such as an alleyway or garden. It is also compatible with underfloor heating which is popular in self-build properties.

Customer Stories

We run it at 22 degrees 24 hours a day, seven days a week and are toasty. We have full time confidence that we will be warm, that cost is not an issue and our arthritis has been less painful.


The ground floor is lovely and warm when we get up in the morning and we've hardly needed the heating on upstairs as the eco-house retains such a lot of heat


The system has quickly adapted to suit our lifestyle and controls both the heat pump and the gas boiler, so we really don't need to worry about anything


Ecodan vs other solutions

In 2019 the Committee on Climate Change demanded that from 2025, new homes should not be connected to the gas grid, with gas boilers being banned in all new-build within the next six years.

Ecodan air source heat pumps are the modern alternative to gas boilers, which were popularised in the 1960s, they can be used both on and off the gas grid, only requiring an electrical connection. Ecodan is the modern renewable alternative to a gas boiler and produces renewable heating and hot water with much lower carbon emissions.

A gas boiler will produce less than 1kW of heat energy for every kW of gas consumed. A heat pump on the other hand harvests renewable energy from the outdoor air so will produce 3 or more kW of heat energy for every kW of electricity consumed.

In comparison to an oil system, an Ecodan air source heat pump is much more efficient, creates lower carbon emissions and has considerably lower operating costs. Also, as they only use electricity and harvest heat energy from the air, there is no need to worry about costly fuel deliveries and the rising costs of oil prices.

An Ecodan air source heat pump will have the largest noticeable impact on your bills and carbon reduction output if you have a direct electric system.
