The enhanced capacity ultra compact HRV1.35 Q Plus continuously running whole-house ventilation unit with heat recovery is independently tested by the BRE and maintains an ultra compact size despite its improved airflow performance.

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.
