Energy Efficient Continuous Heat Recovery for Healthy Air in Kitchens, Bathrooms, Utility Rooms, Living Rooms, Lavatories, Washrooms, Conservatories, Offices and Bedrooms

SKU: HRV 1 Categories: , Brand:

This Heat Recovery Ventilator provide a continuous air change, replacing stale moisture laden air with fresh, warmed air from outside. The units are easy to fit and provide an effective solution to stale, musty indoor air condensation and mould growth problems in any room in which they are fitted.


Unlike conventional extractor fans which suck out and waste expensively produced heat, Single Room Heat Recovery Ventilators (SRHRV) recover up to 86% of exhaust heat, even when operating on boost mode.

The world is becoming increasingly aware of the enormous cost of energy production, and this, plus the use of fossil fuels to generate power, is a momentous environmental issue.

Extractor fans potentially waste over a million kilowatts of energy every year. This is comparable to the total output of two large power stations. Replacing conventional extractor fans with heat recovery systems could save at least half of that energy loss.


The isolating transformer / humidity sensor control unit includes a thumb wheel to adjust the setting for the humidity level at which the fans are switched from trickle to boost mode.

Once set, the thumb wheel can be removed and a blanking plate installed to prevent further adjustment, if desired.


The ‘through the wall unit’ is designed for easy installation by use of a 152mm core drilled hole. Installation is undertaken entirely within a building with no requirement for external access, thus reducing installation costs on High Rise applications.

Suitable for wall thickness from 229mm to 356mm. An extension kit is available for walls up to 1 metre thickness. A window kit is available for installation through single or double glazed windows.

Full installation instructions are provided with the unit.


The unit meets IEE, SELV and Building Regulations.
