What is a heat pump?

Instead of dirty fossil fuels, heat pumps use the power of free fresh air, along with a small amount of electricity, to heat your home and hot water. This makes them four times more efficient than a gas boiler and cheaper to run. Much cheaper.

In fact, they can cut your household heating bills by 25%, all while still providing a cosy indoor temperature all year round. 

What’s more, they’re designed to last much longer than a gas boiler. And, with the Aira Comfort Guarantee, any parts and labour required to ensure the function of your Aira Heat Pump and installation are on us for 15 years.

How much does a heat pump cost?

The cost of installing a heat pump depends on a variety of factors like the size of your home, the total area that needs to be heated and your heating preferences. 

Following your free home energy assessment, we will provide you with a no-obligation quote that includes the £7,500 government grant. We will apply for this on your behalf, so you can sit back and relax.

To make your clean energy switch more accessible, we also provide affordable monthly repayment options as part of our all-inclusive plan. And with 0% VAT to pay, there really is no better time to switch.

I’m so happy with my heat pump. It's so much more efficient than my boiler. The Aira team were excellent and kept me informed every step of the way. I’m looking forward to a cosy heat pump winter!

Do you want to know more about heat pumps?

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.

There is a cost associated with buying a heat pump, you won't get it for free. However, Aira offers affordable prices with the option to spread the costs at equal monthly installments. The costs will depend on various factors such as the size of your property, EPC ratings, and others. The good news is that with the £7,500 boiler upgrade grant the total amount that you need to pay significantly reduces, allowing you to get a heat pump at a discounted rate. 

There are a number of reasons why an air to water heat pump is a worthwhile investment:

  • Heat pumps are four times more efficient than boilers, helping reduce your energy bills. 
  • They also have an average life span of 18 years (almost double that of a typical gas boiler).
  • They are compatible with both underfloor heating and radiators.
  • You can claim the £7,500 government grant and 0% VAT
  • Heat pumps produce 75% fewer emissions and are therefore much more environmentally-friendly than traditional heating systems.

Heat pumps can provide effective heating in temperatures as low as -25 degrees celsius. And because your package includes our Aira Comfort Guarantee at no extra cost, you’re guaranteed 20 degree celsius cosiness on even the coldest day of the year – or we’ll come straight out to fix it.

With the Aira Comfort Guarantee, we promise that our Aira Heat Pumps will continue to provide a cosy indoor temperature for the next 15 years. Or we'll come out to fix it. And, if you want to extend your cover when your 15 years are up, that’s easy and affordable.
