Air Source Heat Pumps- The Eco-Friendly Solution for Your Heating Needs

Air source heat pumps (ASHPs) are becoming an increasingly popular option for homeowners in the UK who are looking for a sustainable and cost-effective way to heat their homes.

One of the main reasons why ASHPs are a good investment is that they are a renewable energy source. Unlike traditional fossil fuel-based heating systems, which rely on burning non-renewable resources such as oil and gas, ASHPs use heat from the air outside to heat a home or building. This means that they produce significantly fewer carbon emissions, making them an environmentally friendly option.

Another benefit of ASHPs is that they are highly efficient. The efficiency of an ASHP is measured by the coefficient of performance (COP), which is the ratio of heat output to energy input. Modern ASHPs have a COP of around 4, which means that for every unit of electricity used, the system produces four units of heat. This makes them significantly more efficient than traditional heating systems, which can have a COP as low as 0.8.

In addition to the environmental and efficiency benefits, ASHPs can also save homeowners money on their energy bills in the long run. While the initial cost of installation can be high, the long-term savings on energy costs can more than offset this. ASHPs also require less maintenance than traditional heating systems, further reducing costs over time.

Types of ASHPs

There are mainly three types of Air source heat pumps, namely a Monobloc System, a Split system and a Hybrid system.

Monobloc system

This type of air source heat pump has all the components housed in one unit, which is typically installed outside the home.


  • More compact and easier to install than split systems.
  • Lower installation cost as there is no need for FGAS approved refrigerant engineers
  • Improved performance in colder climates as all the components are located in one place.

Split system

This type of air source heat pump has an outdoor unit that houses the compressor and heat exchanger and an indoor unit that circulates the heat around the home. The outdoor unit connects to the indoor unit through pipes and electrical cables.


  • Easy to install as it doesn’t require extensive ductwork.
  • More versatile as it can be installed in a variety of locations.
  • Easy maintenance as indoor and outdoor units can be serviced separately.

Hybrid system

This type of air source heat pump combines a conventional boiler system with an air source heat pump.


  • Increased efficiency as the system can switch between the heat pump and boiler to meet heating demands.
  • Increased reliability as the system has a backup heating source in case of pump failure.
  • Offers a backup solution of retaining your boiler for properties that may not be as well insulated and would like to switch between their ASHP and Boiler.

When considering investing in an ASHPs, consulting with a professional is important to determine if the system is a good fit for your home or building. Factors to consider include the size of the space to be heated, the local climate, and the energy efficiency of the existing heating system. It’s also important to ensure that the installer is properly qualified and that the system is installed to the highest standards.
