HRV1.25 Q Plus

Mechanical Ventilation with Heat Recovery unit (MVHR)

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.

Recognised and listed in the UK Product Characteristics Database and includes intelligent humidity options through controller options.

TP406A,TP406HMB/544,TP406B/RH,TP416B/LH,TP416B/RH

Features & Benefits
