Air Source Heat Pumps

Parts for Air Source Heat Pumps

At Varmetec, we supply an extensive range of spare parts for all leading brands of air source heat pumps, helping you keep your renewable heating system running efficiently and reliably. As one of the UK’s trusted heat pump parts specialists, we stock genuine components from major manufacturers such as NIBE, Mitsubishi Electric, Daikin, Samsung, LG, Vaillant, and Stiebel Eltron.

Air source heat pumps are designed for long-term performance, but like any heating system, they require occasional maintenance or replacement parts to maintain efficiency. From compressors, expansion valves, and sensors to fans, controllers, and PCB boards, Varmetec provides the essential components needed for professional repairs and servicing. Every part we supply meets manufacturer standards to ensure compatibility, performance, and reliability.

We work closely with installers, service engineers, and homeowners to ensure fast access to the right parts — backed by expert support and nationwide delivery. Whether you need a replacement sensor for a Daikin unit, a control board for a Mitsubishi system, or general maintenance components, you’ll find them in our carefully curated range.

At Varmetec, we’re committed to supporting the growing UK renewable heating market by making it easier than ever to source genuine spare parts for air source heat pumps. Keep your system running at peak efficiency with quality parts you can trust.
