Why invest in an air source heat pump?

It might seem like a big investment to make the switch from a traditional central heating system to an air source heat pump, however, it can have many benefits. Heat pumps are 4x more efficient than gas boilers and offer you the ability to save 25% on your monthly energy bills.

After finding out how much they could save, Lina and her partner contacted Aira about installing a heat pump at their Victorian terraced flat in southeast London. Despite having no EPC and concerns about whether their property would be able to have a heat pump, Aira made it happen.

How Much Does an Air Source Heat Pump Cost?

The average cost of an air source heat pump with installation is just over £13,000 according to recent government data. However, with the government grant, that net average cost is reduced to £5,500, including any radiators that need upgrading.

With the Aira all-inclusive plan, the savings continue to add up. There are no more upfront costs, just affordable monthly payments. This new way to pay covers every single part of having a heat pump, from installation to aftercare. It's all included.

What affects the price of an air source heat pump?

The price of an air source heat pump changes with the size of the system required. This is set by the size of your home & how well-insulated it is.

Bigger homes, larger ceilings, and more people in your home (especially those with a penchant for long showers) all create stronger demand for more heat.

From loft insulation to triple glazing, insulation is how you can keep hot air inside and cool air out. All heating systems benefit from strong insulation. Insulation stops your heat from escaping, reducing your demand for heat.

How can you reduce your Air Source Heat Pump Running Costs?

Power your heat pump with solar.

Solar panels can reduce your energy bills by 70% whilst adding £5,400 to the value of your property, combine this with an air source heat pump and your efficiency doubles.

Air Source Heat Pump Cost Calculator FAQs

We'll ask some initial questions to check your home is suitable for a heat pump (70% of homes are). We will then help you claim this grant through the Boiler Upgrade Scheme and guide you through the application. We will provide all the support and information you'd need from the initial application to the day of the installation.

A well-designed heat pump system is 4X more efficient than a gas boiler since it captures 75% of the energy required to heat your home from the free outside air. 

The exact cost of running the system depends on the temperature you choose in your home, the amount of hot water you consume, and the price of electricity and the type of electricity tariff you use. 

All Aira Heat Pump systems are designed to perform significantly more efficiently than a gas boiler to optimise CO₂ and heating bill savings. If you don’t have any other gas appliances in your home after switching to a heat pump, you'll be waving goodbye to gas bills for good.

An air source heat pump is much more durable than a gas boiler. It has a longer life span, too. Our heat pumps come with a 10 Year Comfort Guarantee that includes all servicing, maintenance and insurance. This means if you do experience any issues within this period, we will fix them free of charge.
