Air Source Heat Pumps

How ASHPs Work

Our air source heat pumps work by using a compressor to pump refrigerant through a series of coils. The refrigerant absorbs heat from the air outside and is then compressed, which causes it to heat up. This hot refrigerant is passed through another set of coils, where it transfers its heat to the water used for heating your building.

If designed and installed correctly, our heat pumps can also act as air conditioners in the summer. When in cooling mode, the refrigerant absorbs heat from inside the building and releases it outside, effectively cooling the space.

Air Source Heat Pump Installation

Air source heat pump installation requires qualified installers, and involves working with refrigerant and electrical systems. Here’s how we typically carry out the process:

• Site assessment: We begin by assessing your site to ensure it’s suitable for ASHP heating. This includes checking the location for the outdoor unit, the power supply, and the size of your property.
• Design and planning: We design the system and plan the ASHP installation. That includes selecting the right size of heat pump and deciding where to position the indoor and outdoor units.
• Preparation: Before ASHP installation, we handle any necessary preparation. This might involve trenching for refrigerant lines, setting up a base for the outdoor unit, and installing electrical wiring.
• Installation: We then install the system, connecting the indoor and outdoor units, running the refrigerant lines, and wiring it to your building’s electrical system.
• Testing and commissioning: Once installed, we thoroughly test the system. When we’re confident everything’s running as it should, we’ll commission your system and hand over full documentation. That includes MCS certification, warranties, and clear guidance on how to optimise and maintain your system.
