Mechanical Ventilation with Heat Recovery unit (MVHR) BUY NOW

 For use in small to medium sized dwellings

HRV 1.75 Q Plus MVHR UnitThe enhanced capacity HRV1.75 Q Plus continuously running whole house ventilation unit with heat recovery is independently tested by the BRE and remains ultra compact in size despite its results.

Combining extremely low power consumption and a highly efficient heat exchanger, this unit enhances SAP performance via Appendix Q, and yet remains versatile enough in size to be equally as functional in larger apartments as it is in small to medium sized dwellings.
The Eco versions offer a 100% airflow diverting Summer Bypass, recognised and listed in the UK Product Characterists Database. They also include intelligent humidity options and can be fitted with the auralite® status indicator or the aurastat® controller.
