HRV4 Q Plus

Mechanical Ventilation with Heat Recovery unit (MVHR)
MEDIUM TO LARGE SIZED DWELLINGS

Overview

Introducing the new HRV4 Q Plus: a powerful yet compact, continuously running whole-house ventilation unit with heat recovery. It is suitable for larger dwellings and has been independently tested by the BRE. The HRV4 Q Plus delivers cutting-edge performance usually only associated with much larger and more expensive 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 medium sized dwellings.

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