Daikin air source heat pumps

Daikin's range of air-to-water heat pumps is called the Altherma range and it includes heat pumps to suit every kind of home and building project. Able to operate in outdoor temperatures as low as -25°C, the Altherma heat pump generates 3-4 kilowatts of heat for every kilowatt it uses.

The Altherma heat pump has been designed to work alongside existing radiators so in most cases you can keep installation costs to a minimum without having to replace pipework and radiators. In the case of the Altherma Hybrid, you can even run a boiler alongside the heat pump.

Benefits of Daikin heat pumps?

Reduced Energy Bills

Air source heat pumps are highly energy efficient which means they have the potential to lower your energy bills significantly.

Daikin air source heat pumps use 1kW of electricity to extract renewable energy from the air and produce a highly efficient 3-4kW of heat. This heats refrigerant in the system which can then heat your water. So an air source heat pump from actually generates 3 times as much energy as it uses compared to a traditional boiler which turns a maximum 92% of the fuel it uses into energy with the rest being lost as waste gases.

Better for the Environment

Between 65-75% of your Daikin air source heat pump's energy is extracted from the natural air around your home. The small amount of electricity needed to power the heat pump produces only a fraction of the CO? emissions produced by a traditional oil or gas boiler. Depending on the heating fuel and system being replaced, some homes could reduce carbon emissions by as much as 70%.

Easy to Maintain

The average life of a boiler is just 8-10 years but as long as your air source heat pump gets an annual service it should need very little maintenance and many can last for up to 25 years.

Heat Your Home All Year Round

Air source heat pumps by Daikin will work in the worst UK temperatures as they are designed to cope with temperatures as low as -20°C.

Earn Money Through the RHI Scheme

Daikin air source heat pumps are MCS accredited which means the renewable energy generated could earn you money through the government's Renewable Heat Incentive (RHI) scheme.

The RHI scheme pays owners of eligible renewable heating systems for each unit of energy the heat pump generates for 7 years after it has been commissioned. The exact payments you'll receive will vary depending on the current tariff, the technology installed and how much energy you generate.

How much does a Daikin heat pump cost?

To buy and install an air source heat pump you're likely to be looking at costs between £6,000 – £12,000. However, it's important to remember that once the upfront cost is taken care of you can look forward to many years of energy savings and potential earnings through the Renewable Heat Incentive (RHI) scheme which will go a long way towards repaying your investment.

The price you'll pay will depend on the make and model of the heat pump you choose and which company to carries out the installation, as well as the complexity of the work involved.
