Heat Pump Sensors / Switches

Varmetec stocks a comprehensive selection of sensors and switches for heat pump systems, helping maintain accurate control and efficient operation.

Our range includes temperature sensors, pressure switches, flow switches, and safety sensors for air source, ground source, and exhaust air heat pumps. Each part is genuine or manufacturer-approved, ensuring precise performance and reliability.

Sensors and switches play a critical role in monitoring and regulating system functions — from temperature and pressure to flow and fault detection. Replacing worn or faulty components can significantly improve system efficiency and safety.
