Air Source Heat Pumps

Air Source Heat Pumps

Air source heat pumps (ASHPs) absorb energy from the air outside to heat your homes and hot water. They can still extract heat when air temperatures are as low as -15 degrees.

Air source heat pumps need electricity to run but because they are extracting renewable heat from the environment the heat output is greater than the electricity input. This makes ASHPs a very energy efficient method of heating your home.

What We Can Do

We are fully MCS accredited and experienced air source installers. We provide a free consultation discussing your needs to find the perfect renewable heating solution for your home. 

Your Consultation

One of our qualified surveyors will visit your home and discuss with you your requirements and provide options as to what system will best suit your needs. We will then provide a free, comprehensive, no-obligation quotation.

Once the installation is agreed, one of our accredited installers will visit your home, and install the air source heat pump.

Government Financial Support

You may be eligible to receive payments for the heat you generate using a heat pump through the UK Government’s Renewable Heat Incentive (RHI).

Boiler Upgrade Scheme

The Government will provide grants to encourage property owners to install low carbon heating systems such as heat pumps, through the Boiler Upgrade Scheme. These grants will help property owners overcome the upfront cost of low carbon heating technologies.

The Scheme will open to domestic and small non-domestic properties in England and Wales. It will run from 2022 to 2025.

The Scheme opens on the 23rd May 2022 for grant applications and payments.


What You'll Get:

Depending on the type of renewable heating technology you opt for, you can receive the following:

  • £5,000 off the cost and installation of air source heat pump.
  • £5,000 off the cost and installation of a biomass boiler.
  • £6,000 off the cost and installation of a ground source heat pump.

Who is eligible?

You may be eligible if you:

  • Live in England or Wales
  • own your property (whether this is a home or small non-domestic property)

The property will need to have:

  • an installation capacity of up to 45kWth (this covers most homes)
  • a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation.

New build properties will not normally be eligible. The only exception is if you’re building your own home.

How the Scheme will Work:

We, as the installer, will apply for the grant on your behalf. The value of the grant will be discounted off the price you pay.

  1. You will need an MSC accredited installer, we at Bridge Heating are fully accredited, you can trust in us to provide a competent service and quality installation.
  2. We will advise you on whether an installation is eligible for a grant.
  3. We will agree a quotation for the installation.
  4. We will apply for the grant.
  5. You confirm that the installer is acting on your behalf when you’re contact by Ofgem.

How much do they cost to install?


The cost of installing an air source heat pump  will depend on the size of the property it needs to heat. On top of this you might have any additional works required to upgrade the heat distribution system. Generally speaking installing a heat pump is not especially disruptive work, though you may want to carry out this work at the same time as other home renovations.

We can provide you with a free no-obligation quotation for installing an air source heat pump that suits your homes requirements.


How much you can save will depend on the system that you use now, as well as what you are replacing it with. Your savings will be affected by:

  • Your Heat Distribution System Underfloor heating can be more efficient than radiators because the water doesn’t need to be so hot. if underfloor heating is not possible, we advise you to use the largest radiators you can.
  • Your Fuel Costs You will still have to pay fuel bills with a heat pump because it is powered by electricity, but you are likely to save money on your fuel bills (depending on the type of heating you are replacing).
  • Your Old Heating System If your old heating system was inefficient, you are more likely to see lower running costs with a new heat pump.
  • Water Heating If the heat pump is providing hot water, then this could limit the overall efficiency. You might want to consider solar water heating to provide hot water in the summer and help keep your heat pump efficiency up.
  • Using Controls – Learning how to control your system to get the most out of it important. You will probably need to set the heating to come on for longer hours, but you might be able to set the thermostat lower and still feel warm. We can advise and explain how you can control your system so you can use it most effectively.

Types of Air Source Heat Pump


Air-to-Water heat pumps absorbs heat from the outside air and transfer the heat to water.

An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperatures than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over long periods of time.


Air-to-air heat pumps require a warm air circulation system to move the warm air around your home. They will not provide you with the hot water as well. Air-to-air heat pumps are not eligible for the UK government’s Renewable Heating Incentive scheme.


Heat pump systems typically come with a warranty of two to three years. Workmanship warranties for heat pumps can last up to 10 years for example, through Quality Assured National Warranties (QANW). Many manufacturers also offer options for warranty extensions for a fee.

With regular scheduled maintenance, you can expect an air source heat pump to operate for 20 years or more.

Every year, you should check that the air inlet grill and evaporator are free from leaves or other debris. Remove any plants that start to grow near the heat pump. You may also be advised by your installer to check the central heating pressure gauge in your house from time to time.

We can provide you with written details regarding the maintenance checks you should undertake to ensure everything is working properly. We can advise you on the maintenance requirements before you commit to installing a heat pump.
