SMALL TO MEDIUM SIZED DWELLINGS
Buy

Overview

The enhanced capacity ultra compact HRV1.25 Q Plus continuously running whole-house ventilation unit with heat recovery is independently tested by the BRE.

Combining ultra low power consumption and a highly efficient heat exchanger, the HRV1.25 Q Plus is specifically designed to enhance SAP performance via Appendix Q – yet the unit remains small enough to be easily incorporated into apartments and smaller houses where space is at a premium.

The HRV1.25 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).
