HRV1.75 Q Plus (Obsolete)

Mechanical Ventilation with Heat Recovery unit (MVHR)

The enhanced capacity HRV1.75 Q Plus continuously running whole-house ventilation unit with heat recovery is independently tested by the BRE maintains an ultra compact size despite its improved 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 HRV1.75 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.
