HRV 3 Q Plus

Mechanical Ventilation with Heat Recovery unit (MVHR)BUY NOW

For use in large sized dwellings

HRV3 Q Plus MVHRSuitable for larger dwellings, the HRV3 Q Plus continuously running whole house ventilation unit with heat recovery is independently tested by the BRE. The HRV3 Q Plus gives cutting edge performance usually only associated with much larger and more costly products.

The combination of very low power consumption and a highly efficient heat exchanger is specifically designed to enhance SAP performance via Appendix Q, yet small enough to be easily incorporated into medium sized dwellings.

The Eco versions offer a 100% airflow diverting Summer Bypass, recognised and listed in the UK Product Characteristics Database. They also include intelligent humidity options and can be fitted with the auralite® status indicator or the aurastat® controller.

Features & Benefits
