Buy

Overview

The enhanced capacity HRV2.85 Q Plus continuously running whole-house ventilation unit with heat recovery has been specifically designed to give improved performance over older models, in line with new build design requirements. It is independently tested by the BRE.

Combining extremely low power consumption and a highly efficient heat exchanger, the HRV2.85 Q Plus is specifically designed to enhance SAP performance via Appendix Q, yet still small enough to be easily incorporated into medium or large sized dwellings.

The HRV2.85 Q Plus Range of MVHR unit comes in three different models; our ‘A’ model which is our basic version and our ‘HMB’ & ‘B’ models which are part of our Eco version range.  Each set out to accommodate our customers’ needs.

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, aura-t™ (HMB and B models), auramode® and aurastat® controllers (B models only).
