Heat Recovery Ventilation Systems for Energy-Efficient Homes and Workspaces

Improve indoor air quality while reducing energy costs with our advanced range of heat recovery ventilation systems. At Electricals Online, we offer cutting-edge solutions from leading brands such as Envirovent, Blauberg, and Vent-Axia, designed to deliver fresh, filtered air while retaining up to 85% of the heat that would otherwise be lost through traditional ventilation.

Our collection includes both whole-house PIV (Positive Input Ventilation) systems and decentralised single-room heat recovery units, ideal for bathrooms, kitchens, lofts, and living spaces. These systems are engineered to combat condensation, damp, and stale air, creating a healthier and more comfortable indoor environment. With features like smart Wi-Fi controls, whisper-quiet operation, and energy-efficient motors, our heat recovery units are perfect for modern homes and energy-conscious renovations.
