Ultra energy efficient Heat Recovery Ventilation unit

For use in large dwellings

HRV3 PH ECOaura MVHRSuitable for larger dwellings, the HRV3 PH ECOaura continuously running whole-house ventilation unit with heat recovery is independently tested and is Passivhaus certified. The HRV3 PH ECOaura 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 performance, yet small enough to be easily incorporated into medium sized dwellings.

Our HRV3 PH ECOaura has 100% airflow diverting SummerBypass functionality that offers intelligent humidity options and is fitted with either our aurastat® or aura-t™ controllers.
