For use in medium to large sized dwellings

HRV2.75 Q PlusThe compact HRV2.75 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. This increased performance is achieved with a unit size no larger than the HRV2 Q Plus. The unit is independently tested by the BRE and is EST Best Practice compliant.

The combination of extremely low power consumption and a highly efficient heat exchanger is specifically designed to enhance SAP performance via Appendix Q, yet still small enough to be easily incorporated into larger apartments or medium to large sized dwellings. The HRV2.75 Q Plus Mechanical Ventilation with Heat Recovery unit has many features and is available with a variety of options, including Summer Bypass, SUMMERboost® and Humidity Sensor.

Features & Benefits
