Air Source Heat Pump Installations – what homeowners need to know

Installers should complete a thorough handover with homeowners about their heat pump

Air source heat pumps are a low carbon heating solution that homeowners can install at their homes to fulfil their heating requirements. With lots of choice, the heat pump market can be a confusing place for consumers so in this blog, we will explore some of the key considerations homeowners should be aware of when planning an air source heat pump installation.

While air source heat pumps operate differently to traditional heating systems, such as a gas boiler, they are a reliable, more eco-friendly solution for keeping our homes warm. If you are considering installing an air source heat pump, this will not only reduce the carbon footprint of your home but also significantly reduce your reliance on fossil fuels. Furthermore, to help homeowners make the transition from gas or oil boilers to renewable heat pumps, the Government’s Boiler Upgrade Scheme is currently available to provide funding of up to £7,500 to help reduce the installation costs of an air source heat pump.

In this blog, we will take a closer look at heat pump technology, how to get a quotation for your new system as well as providing useful links to other resources which will help your research.

What is an air source heat pump

To learn more about how an air source heat pump works, please visit the Education Area in our Knowledge Hub where we explain this in more detail. In short, an air-to-water air source heat pump, such as the Grant Aerona³, extracts heat energy from the air outside and transfers this into useable heat that can warm your home. Air source heat pumps today are incredibly efficient and offer homeowners a more environmentally friendly, low carbon solution for heating their home compared to traditional fossil fuel boilers.

How do I find the right air source heat pump installer?

Designing and installing an air source heat pump system is different to working with a central heating system that features a gas or oil boiler so it is important that you choose the right professional to install your air source heat pump. Air source heat pumps are low temperature systems so they need to be thoroughly designed with a comprehensive site survey and heat loss calculation carried out, the correct output of heat pump selected and the appropriate heat emitters sized and specified as well. Installers should therefore have completed relevant manufacturer product training.

Research local installers

To find local heat pump installers in your area, you can use the Find an Installer search on our website. This search will help you locate G1 Installers who fit Grant air source heat pumps in your area. We would recommend that you contact more than one installer to obtain different quotations to compare.

Ask for recommendations

As part of your research, you could also seek recommendations from friends, family or local neighbours who have already made the move to renewables and had an air source heat pump installed in their home. Customer reviews can also be useful to read so you can visit your installer’s website to view their testimonials.

Request multiple quotes

As mentioned above, it is recommended that homeowners researching a new heating system contact more than one installer so that they can view different quotes to compare their prices and services. This will help you make an informed decision, ensuring that your heat pump installation costs remain within budget while also making sure the system is specified to meet your home’s specific needs.

The process of installing an air source heat pump

The installation process for an air source heat pump will comprise of the following:

  • Site Survey followed by sizing and specification
  • Check electricity supply requirements including DNO application (where applicable)
  • Installation of the heat pump and system connections followed by commissioning
  • Comprehensive customer handover explaining how the system works, how to operate the controls and how to maintain and look after the air source heat pump

We expand each of the above steps and explore them in greater detail in our online Knowledge Hub so please read our article - How to choose the right air source heat pump for your home.

Can air source heat pumps work with radiators?

Yes, air source heat pumps can be installed with traditional radiators but it is important that they are correctly sized. Air source heat pumps are low temperature systems which means that the water flow temperature is lower than a traditional heating system using a boiler and therefore a larger surface area is required to emit heat into a room. This is why heat pumps are often installed with underfloor heating or with a combination of UFH and radiators. However, provided the radiator sizes are correctly designed, radiators can be installed with a heat pump.
