Your complete guide to air source heat pumps.

Learn about the heating systems everyone’s getting pumped up about.

Interested in upgrading from your old boiler to a shiny new air source heat pump? Here, you’ll find everything you need to know about heat pumps - including what they are, how they work, and why they’re a great energy-efficient solution for your heating and hot water. You can also see how they could help save you money, reduce your carbon footprint, and why thousands in the UK are already making the switch.

Heat pumps in a nutshell.

Find out what a heat pump is, how they work and why they’re better for the environment than older heating systems.

How you can benefit and save with an air source heat pump.

Air source heat pumps (ASHPs) are the latest in home energy tech, taking warmth from the outside air, or ground, and using it to heat your home or provide your hot water.

Heat pumps are typically 3 to 4 times more efficient than older heating systems so they can reduce your carbon footprint and your heating costs.1

Find out more including the different types available, if they’re right for you, what’s involved in installation, and how much you could save if you switch to an air source heat pump.

1 Potential annual savings are based on the installing of a standard air source heat pump in an average sized three-bedroom detached home. Savings are dependent on your property size, your household electricity usage, the current of any existing electric storage heater used and its age. Savings are dependent on the current oil/LPG system used, and their age. Figures are sourced from the Energy Saving Trust website.

Grants for heat pumps.

Did you know you could get a government grant to help make getting a heat pump more affordable?

Grants for heat pumps are easy and simple to apply for:

  • The Boiler Upgrade Scheme (BUS): In England and Wales.

  • The Home Energy Scotland grant: If you’re in Scotland.

  • The Northern Ireland Sustainable Energy Programme: For Northern Island.

Find out if you’re eligible, how you can apply, and whether you could claim a £7,500 (BUS) grant for an air source heat pump for your home.2

2 The Government’s Boiler Upgrade Scheme is valid for heat pumps that are commissioned from 1 April 2022. To be eligible for the grant, a valid Energy Performance Certificate (EPC) from the last 10 years. Unfortunately new build homes are ineligible for the Boiler Upgrade Scheme. Owner and property eligibility apply. To see the full eligibility criteria and exclusions, visit the Government Boiler Upgrade Scheme website.

How do heat pumps work?

Air source heat pumps might sound complicated but they’re actually quite simple.

They take air outside your home and extract the heat from it to heat your home and provide your hot water. The process is called ‘air pump heating’ and the cycle works like this:

  • Absorb. The heat pump's outdoor unit soaks up heat from the air.

  • Boost. The heat is "boosted" to make it even warmer.

  • Transfer. This boosted warmth is sent to your home's heating system.

  • Repeat. The cycle continues all year round (yes even in winter).

Heat pumps vs boilers, find the right solution for you.

Choosing the right energy tech for your home is important.

And comparing air source heat pumps and boilers can be tricky.

To help you make an informed choice, we’ve weighed up all the key factors you need to consider. Whether it’s reducing your heating costs, increasing energy efficiency, or lowering your carbon footprint – we can help find the right solution for you.

Ground source vs air source heat pumps.

Broadly speaking, there are two main types of heat pump.

  • Air source heat pumps (ASHPs) harness natural energy from the air outside to heat your home and provide you with hot water.

  • Ground source heat pumps (GSHPs) work in similar ways, harnessing natural energy from the ground.

To help you choose the right one for you, we’ve compared and explored their efficiency, installation costs, and suitability for different homes. Read more about ground source vs air source heat pumps.

Heat pump facts.

In this article we’ll deep dive into the world of air source heat pumps (ASHPs), and see how this amazing tech can be a game changer for you.

We’ll give you the truth about ASHP’s energy efficiency, cost-saving potential, and environmental benefits – plus, dispel any myths or misconceptions you may have.

Heat pump heating costs.

Getting an air source heat pump (ASHP) is a sizeable investment.

So it’s worth knowing all about heat pump heating and running costs. Here, we look at how much you could save in a month or year when compared to a traditional gas boiler.

Heat pump’s running costs depend on:

  • The size of your home.

  • Your home's insulation.

  • Your current energy prices.

  • Your heating habits.

Only when you’ve weighed up your ASHP’s heating costs, running costs, and efficiency, can you make a truly informed decision about your home heating tech.
