What is an air source heat pump?


An air-source heat pump (or ASHP) is a system that transfers heat from inside of a building to the outside or vice versa. By obeying the principles of vapor compression refrigeration, an ASHP makes use of a refrigerant system involving a condenser and a compressor to abort heat at a certain place and release it at a different location. This can either be used as a cooler or a heater and are often referred to as reverse-cycle air conditioners.

In domestic heating use, an ASHP takes in heat from the air outside and releases it inside the building as domestic hot water supply, underfloor heating, hot water-filled radiators, or hot air. When specified correctly, an ASHP can offer a full domestic hot water and central heating solution up to 80 °C.

Benefits of installing an air source heat pump in your house


  1. Lengthy lifespan: The lifespan of heat pumps is quite long, running for up to 50 years. However, the average lifespan lies between 14-15 years – which is still good. Plus, they offer a steady source of heat and are exceptionally reliable.
  2. Fewer carbon emissions: ASHP reduces your carbon emissions dramatically, and its conversion rate of energy to heat is quite efficient. For instance, the efficiencies of ASHP reach quite high, nearly 600%, to be precise.
  3. Less maintenance: In comparison to combustion heating systems, ASHP doesn’t require much maintenance. However, few details of the system have to be checked on an annual basis, which you can easily accomplish by yourself. On the other hand, a professional installer has to check ASHP every 3-5 years.
  4. Eligibility of RHI scheme: The government offers two different types of programs to help in the installation of renewable energy systems. Under the domestic RHI (or renewable heat incentive) scheme, you may be eligible for payment. This scheme addresses to self-builders, private and social landlords, and homeowners. On the contrary, the non-domestic RHI is open to the public sector, like industries, organisations, and businesses.
  5. Offers cooling: During warmer periods, heat pumps can reverse the process, thereby acting as an AC unit. During summers, ASHP may be switched to cooling mode.
  6. Offers safety: In comparison to combustion-based heating systems, ASHP is far safer.
  7. Reduces running costs: In comparison to systems based on combustion, heat pumps are cheaper to run. If your systems are energy-efficient, you can attain greater, long-term savings on energy.


Is an air source heat pump worth it?


Definitely! The benefits that heat pumps offer indicate that they represent a smart investment in the long run. You can save a lot on your running costs, which will show on your energy bills. This is because all the mechanism does move the heat from a certain space to another, and no heat is produced. What’s more? The government helps you in your transition towards a green energy solution. While you may regard the high upfront costs, you would also need to see the big picture simultaneously. Heat pumps plus solar applications equal to a path to zero net energy.
