Air Source Heat Pump

Choosing an air source heat pump for your home is an excellent way to help the planet, contribute to the UK’s efforts to have net zero carbon emissions by 2050 and save yourself money on your energy bills.

Switching from an old (G rated) gas boiler or electric storage heaters to an air source heat pump could save you between £385 and £830 per year (based on a 3 bed semi-detached home)*. Also, it could save between 2900kg and 2000kg of carbon emissions per year.

Plus, the government is currently offering a £7,500 grant as part of its Boiler Upgrade Scheme to home-owners looking to switch from a gas boiler to low-carbon air source heat pump.

How an air source
heat pump works

In a nutshell, an air source heat pump takes energy from the air outside and uses it to heat water which then warms living spaces via radiators or underfloor heating.

In more detail, the heat pump gathers the energy in the air outside and then uses it to heat a special fluid (typically a refrigerant). As the fluid warms up, it becomes a gas. The warmth in the gas is then compressed to increase its temperature further. This heat then warms the water in your radiators, underfloor heating, hot taps or showers.

Heat pumps work on a cycle and once the gas has warmed the water, it cools down, reverts to a liquid and the cycle of heat transfer begins again.

The whole process is powered by electricity but compared to the output of heat generated, heat pumps are highly efficient and low-carbon.

£7,500 government grants available

As an accredited installer, we can access a £7,500 government grant towards the cost of your heat pump as part of the Boiler Upgrade Scheme to encourage homeowners to switch from gas boilers to low-carbon heat pumps.

We’ll confirm your eligibility during a home visit.

Anyone who is considering a boiler replacement, may like to think about choosing a more sustainable option: a heat pump. A heat pump will reduce your heating bill significantly and reduce your property’s carbon emissions dramatically too.

It’s an excellent way to introduce renewable energy into your life and do your bit to help the UK’s mission to become net zero.

Who needs an air source heat pump?

Home visits to suit you

We’ll ask a few questions over the phone and then book you a FREE home visit at a time to suit you.

Our experts have been installing heat pumps for years so are perfectly experienced and qualified to specify the best size and configuration of heat pump for your home and energy usage. Our happy customers are a testament to the excellent service we offer before, during and after the installation.

Saving money

There are numerous considerations when calculating how much a heat pump will save you on your energy bill but the indicative savings are impressive. During our home visit we’ll take into account the following factors to give you an accurate expected saving per year:

Efficient, efficient, efficient

An air source heat pump is designed to last around 20 years (25% longer than a gas boiler) and is around 3 times more efficient than traditional gas boilers because hardly any energy is wasted during its process of heating water. Very clever technology!

Getting the most from your home heating

Choosing to go green with a heat pump is a great way to future-proof your home as the government begins to introduce legislation to make it mandatory, starting with the ban on gas boilers in any newly built property from 2035 onwards. The UK government has a big target to reach net-zero by 2050** and your contribution will help.

The government estimates that millions of heat pumps will be installed in the UK in the coming years.

Heat Pump FAQs

What is an air source heat pump?

An air source heat pump takes thermal energy from the air outside and transfers that heat to the inside of the home. The clever technology works even when temperatures outside are below zero.

Are there other types of heat pump?

Yes, ground source heat pumps are also available but not currently a service offered by Evolve.

Why should I have an air source heat pump?

They are around three times more efficient than a boiler so they are an excellent choice if you have an old boiler that needs replacing. The UK government is working towards phasing out the installation of new boilers, in favour of heat pumps because of their excellent energy efficient performance.

How long does an air source heat pump take to install?

Around two to five days is typical but it varies from property to property, depending on what the heat pump is replacing, the configuration of the heating system and property size. Our Home Energy Surveyor will advise during their home visit.

How much money can an air source heat pump save me on my heating bills?

£100s per year on your heating bill but it’s hard to be more specific than that without assessing your current energy usage, current heating system, heating demand and property size. Our Home Energy Surveyor will advise during their home visit.
