Our heat pumps are first-choice for high-specification properties thanks to their superior performance and enhanced zone control and ability to easily connect with swimming pools and solar thermal to provide one complete system. We also offer the most advanced compact heat pump available in the UK, the AQ17i, providing the perfect solution for smaller properties.

Air Source Heat Pumps

Air source heat pumps are a popular choice with homeowners, particularly for existing properties as they can be installed quickly, in as little as 1-2 days. Our BoxAir Inverter is a high performance air to water heat pump available in outputs of 5-22kW and achieving SCOP ratings up to 4,49 (A+++). We also provide commercial grade air source heat pumps for properties with a higher heat demand and can cascade two or more units to deliver signifcant outputs.
