HRV 1.5 Q Plus

Mechanical Ventilation with Heat Recovery unit (MVHR)



HRV1.5 Q Plus MVHR Unit

The compact HRV1.5 Q Plus continuously running whole house ventilation unit with heat recovery is independently tested by the BRE and is EST Best Practice compliant. The HRV1.5 Q Plus gives cutting edge performance usually only
associated with much larger and more costly products.

The combination of very low power consumption and a highly efficient heat exchanger is specifically designed to enhance SAP performance via Appendix Q, yet small enough to be easily incorporated into larger apartments or small to medium sized dwellings. The HRV1.5 Q Plus MVHR unit is now available with improved features and in three model options, two of which include Summer Bypass.

Features & Benefits

  • Compact unit can be fitted in cupboards or loft spaces
  • Very low power consumption / specific fan power
  • Highly efficient heat exchanger; up to 91%
  • Three versions available (all the same dimensions): 'Standard', 'Summer Bypass and Duct Heater Connection', or 'Summer Bypass c/w SUMMERboost and Duct Heater Connection'
  • Standard version has a Summer Mode feature to help reduce dwelling overheating
  • Intelligent controller, quick and easy to commission
  • Fully adjustable boost overrun timer 0-60 minutes; can be used with non-latching (momentary) switches to prevent unit from being accidently left in boost mode
