Air Source Heat Pumps

What is an Air Source Heat Pump?

An Air source heat pump is a highly efficient water heater. Heat pumps can produce the hot water and heating needs of a home or commercial building. They use refrigerant technology to absorb energy from the outdoor air through an outdoor unit and transfer this energy to your heating and/or hot water. Consequently, you can typically expect to gain 3-5kW (units of energy) from the outdoor air for every 1kW of electricity used to harness this energy.

Not all Air Source Heat Pumps are the same, and each model has its own conversion rate.

Most of these appliances are designed to generate up to 55 degrees Celsius of Hot water temperature without any other form of boiler/ heating element.

And are typically installed with heating systems designed to operate between 35 and 45 degrees Celsius.

Is an Air Source Heat Pump Suitable for me?

The lower temperature systems are generally more suitable for new build and renovation projects, as the design of the heating system can be considered. This means that the heating system would be designed to operate in the most efficient parameters of the heat pump installed.

When looking to retro fit an air source heat pump in your home, there are usually two options available, one being to upgrade the system you have in place already, such as installing new radiator with higher heating outputs where needed. Another option is to fit a high temperature air source heat pump unit. These Units are designed to operate at higher temperatures similar to those of a conventional fossil fuel boiler.

What is the installation process?

  • The first step of the installation process is to design an air source heating system for your home or building. This process starts with a heat loss calculation of the property being heated. Once these calculations have been done a system can be specified to meet the demands of the building.
  • If the installation is in an existing building with an existing heat source, the next step in the process is to remove any elements of the previous heating system that are being replaced by the new design. This could include a boiler, radiators that are too small and/or a hot water cylinder.
  • Once the existing is removed or in the case of a new build property the third step is to install the heat emitters. These can be radiators, underfloor heating, fan coils or any other appropriate equipment.
  • The final step is the installation itself; the outdoor unit needs to be connected to the internal plumbing, and/or equipment. A typical installation can take between a few days and week. Larger or more complex installations can take longer.

How much is it likely to cost?

An air source heat pump installation can vary wildly in cost depending on the property. Typically, an installation will cost between £8,000 and £12,000. These costs vary on a wide variety of factors such as the size of the building, the location of all the equipment, and electrical works that my be required and any upgrading works that may be needed to create an effective system.
