Technical Data:

HRV Q Plus

Highly Efficient Heat Recovery Ventilation Units The revolutionary, ultra-compact HRV Q Plus continuously-running whole-house ventilation unit with heat recovery is independently tested to the highest standards. The HRV Q Plus has been specifically designed to give improved performance over older models without increasing the overall size of the unit. The combination of ultra low power consumption and a highly efficient heat exchanger 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 it at a premium. The HRV Q Plus Mechanical Ventilation with Heat Recovery unit has many new features including removable airtight filter covers for easy access to filter maintenance.
How it works A centrally located, continuously-running, mechanical supply  and extract fan extracts air via ducts from moisture-producing areas or ‘wet rooms’ such as kitchens and bathrooms to remove odours and excessive humidity. The air is passed over the heat exchanger, which transfers a high proportion of the heat of the extract air to the incoming air, which is then distributed to the habitable rooms via ducts. Whole-building ventilation is maintained by a contrast flow of air between input and extract points. A boost facility provides rapid extraction when necessary to remove higher levels of pollutants and humidity. As an alternative, every room may  have an individual unit as opposed to a centrally located and ducted unit.
Very Lightweight for easy handling Very compact - can fit into airing cupboards, small services cupboards and loft spaces.
