What is an air to air heat pump?

Air to air heat pump

An air to air heat pump is a heating and cooling device that transfers warm or cool air from the air outside into your home. This happens via a ventilation fan system. 

Air to air heat pumps are known for their high efficiency rates, which can reach up to 300%. This means that for each unit of electricity that the heat pump consumes, it produces up to 3 times as much heating or cooling. 

This energy system also boasts a lifespan of between 10 - 15 years. What this means is that, once installed, you can enjoy benefits such as reduced running costs and lower carbon emissions for years to come.

How does an air to air heat pump work?

An air to air heat pump works by absorbing air from outside into a refrigerant, which is then compressed, warmed up, and released into your home as hot air. The heat is distributed via a ventilation system. 

For the cooling process, the warm air inside your home is absorbed and the refrigerant that is heated from it travels outside, where it is cooled down by the outdoor air. The cooled refrigerant is then transferred back inside, ready to repeat the process.

As you can see, air to air heat pump costs in the UK are quite high. Once installed, your air to air heat pump will bring some savings to your yearly heating bills. However, it’s important to note that it will only be able to attend to your household’s heating needs, so you would still need to spend money on a system that ensures your hot water supply. 

Whatever your situation, you can lessen the financial burden of installing an air to air heat pump by making use of the government grants available in the UK. One such incentive is the Boiler Upgrade Scheme, with which you can receive up to £7,500 to install an air to air heat pump.

Some other grants for air to air heat pumps include: Energy Company Obligation (ECO4), Warmer Homes Scotland, Home Energy Scotland, Warm Homes Programme Wales, and The Northern Ireland Sustainable Energy Programme. You can check how much you can save with each of these heat pump grants to avoid overspending on an air to air heat pump. 

Need more help deciding whether an air to air heat pump is the right choice for you? Then you’ll need to find a reliable installer to consult with. However, this is not exactly easy to do on your own. You could spend hours or even days googling local installers, with no guarantee that you’ll have found what you’re looking for.

Air to air heat pump advantages

Air to air heat pump pros
  • Easy installation: Air to air heat pumps are the easiest kind of heat pump to install. The installation process can usually be completed in 1 - 2 days. All that’s needed is for the indoor and outdoor units to be installed and connected. 
  • Highly efficient: Air to air heat pumps are about 200 - 250% efficient. This is generally measured through a Coefficient of Performance (CoP) of 2 to 2.5. This means that for each unit of electricity that the heat pump consumes to operate, it produces 2 - 2.5 units of usable energy. 
  • Versatile: This renewable energy source works for both heating and cooling. This means that just one appliance does the job of both a boiler and an air conditioner. The heating and cooling processes can easily alternate depending on the season and your needs. 
  • Can be paired with other systems: An air to air heat pump can easily be paired with other traditional or renewable energy systems. For instance, it’s compatible with boilers, if you’re looking to install a hybrid heating system. It can also be paired with solar panels to run on clean energy. 
  • Minimal maintenance: Once installed, air to air heat pumps require little to no maintenance. Generally, it’s advisable to have your system serviced once every 2 - 3 years to ensure that it can run optimally for years to come. 
  • Increased home safety: Since they run on electricity, air to air heat pumps reduce the risk of accidents caused by combustible fuel types such as gas. This makes them a safer option for any household. 

Air to air heat pump disadvantages

Air to air heat pump cons
  • Seasonal dependency: Air to air heat pumps lose some of their efficiency when temperatures drop below -10°C. When this happens, they consume more electricity to generate the same amount of energy they normally produce for your home. 
  • Dust distribution: Because they use a fan ventilation system to transfer heat from outside into your home, they can also sometimes bring dust into your home. 
  • Lower heat supply: Compared to some other energy systems, air to air heat pumps offer a more limited heating supply. As a result, you may need an appliance with a larger power output size to attend to your household’s energy needs. 
  • Potential noisy operation: While most air to air heat pumps are known for their quiet operation, in some cases you may experience some disruptions to the comfort of your home. Generally, the noise levels are comparable to those of an air conditioner. 

Is an air to air heat pump suitable for my household?

Air to air heat pumps are an excellent option if you’re looking to reduce your carbon footprint, as well as your yearly energy bills. On top of that, air to air heat pumps are easy to install and take up relatively little space, making them suitable for virtually any kind of home.

With energy efficiency levels of up to 300% and different power output availability, air to air heat pumps can attend to the needs of most household sizes. However, even with all these impressive benefits, it doesn’t necessarily mean that they’re the best option for your home. 

If you’re still on the fence about an air to air heat pump installation, you will need to consult a professional who can offer you tailored advice. Yet, finding someone you can trust can be an overwhelming process involving seemingly endless browsing.
