Are You Thinking About an Air Source Heat Pump?

Here's What You Need to Know First

With energy bills rising and more homeowners turning to greener alternatives, air source heat pumps (ASHPs) are growing in popularity. But before making the switch, there are a few key things to consider to ensure it's the right solution for your home—and to make the most of your investment.

Here’s what you should think about before installing an air source heat pump:

1. Is Your Home Suitable?
   Air source heat pumps work best in well-insulated homes. If your property loses heat quickly through walls, windows, or the roof, your pump will have to work harder—making it less efficient.
   👉 Tip: You may want to improve insulation or draught-proofing before installation.
2. Outdoor Space
   ASHPs need to be installed outside your home—typically at ground level, with good airflow around the unit.
   👉 Ask yourself: Do I have a suitable outdoor space that’s easy to access for servicing?
3. Radiators or Underfloor Heating?
   Heat pumps run at a lower temperature than traditional boilers, so larger radiators will probably be required to keep your home warm.
   👉 You may need to upgrade your radiators.
4. Noise Levels
   Modern air source heat pumps are quiet—but not silent. It’s worth thinking about placement so that the unit doesn’t disturb you or your neighbours.
   👉 Consider installing it away from bedroom windows or neighbouring walls.
5. Hot Water Storage
   Most ASHPs require a hot water cylinder, so if you’re currently using a combi boiler system (which heats water on demand), you will need space for a hot water cylinder.
   👉 We’ll help assess the best layout for your home.
6. Running Costs vs. Savings
   While heat pumps can significantly reduce your carbon footprint and save you money long-term, upfront costs can be higher than a new boiler.
   👉 The good news? The Boiler Upgrade Scheme offers a £7,500 grant to help offset installation costs.
7. Choose an MCS-Accredited Installer
   Only MCS-accredited installers can help you access government funding and guarantee your system meets quality and efficiency standards.
