If you have recently seen our TV ad and would like to convince yourself of the benefits of choosing a Daikin Altherma heat pump for your home, this page gives you all the information you need. 

At Daikin, we’re one of the world’s leading heat pump manufacturers with decades of expertise under our belt. So, while heat pumps may seem like a new technology, there are already more than 900,000 Daikin Altherma renewable heating systems in homes across Europe. We have collected the most important figures for you and you can get expert advice on performance and installation from one of our Sustainable Home Network installers.

A heat pump uses renewable energy from the air to heat your home and provide hot tap water. It extracts heat from the air and transfers that heat into your radiators or underfloor heating system. That's how our products can achieve significant carbon and running cost savings compared to fossil fuel heating systems.

Lifecycle carbon savings

If you’re concerned about your carbon footprint, the case for heat pumps is compelling.

A report featured by the BBC in May 2020 includes heat pumps as one of the top 10 ways to reduce your carbon footprint, reducing carbon emissions by 0.795 tonnes per person every year1 – a major change in the right direction.

Our most efficient heat pump, the Daikin Altherma low temperature system, saves up to 45% of carbon emissions compared to a gas boiler, and 59% of carbon emissions emitted by an oil or LPG boiler – a reduction of up to 46.9 tonnes of carbon emissions from your home over your heat pump’s expected 15 year lifetime, compared with using oil or LPG. That's a massive impact, even more than living car free, which saves an average of 2.04 tonnes of CO2 equivalent per person annually.2

Lifecycle cost savings

We all know heating bills quickly add up. When you install a heat pump, you could save up to £476 per year compared with an oil boiler and up to £377 compared with a gas boiler, simply by being more energy efficient.

What’s more, you can also receive additional income from government funding and payment schemes, to even further offset the costs of installing your system, and making your heat pump an even more economical choice. You can find out more about eligibility conditions and the different schemes in our funding hub.

Over the expected lifetime of your heating system, it’s clear to see how a heat pump is a much more economical cost compared with any fossil fuel boiler.
