HRV or ERV Ventilation \u2013 Two Solutions from Blauberg AirOne<\/h2>\n

Blauberg AirOne<\/strong> is a local heat recovery ventilation unit available in both HRV and ERV configurations<\/strong>. Both bring fresh outdoor air into the room, remove stale indoor air, and reduce heat loss associated with ventilation.<\/p>\n

The main difference lies in humidity:<\/p>\n

Blauberg AirOne HRV<\/strong><\/a> recovery heat from the exhaust air, while Blauberg AirOne ERV<\/strong><\/a> allows some of the moisture to be recovered in addition to the heat.<\/p>\n

Therefore, the choice between HRV and ERV is not about which unit is better, but rather which AirOne version is better suited to the indoor climate of a specific home<\/strong>.<\/p>\n

Blauberg AirOne HRV \u2013 if you want to remove more moisture<\/h3>\n

The AirOne HRV<\/strong> is well-suited for homes where high humidity, window condensation, or the need to effectively remove moisture from the building via ventilation are issues.<\/p>\n

The HRV version uses the heat from the exhaust air to heat fresh outdoor air, but is not designed to recover moisture.<\/p>\n

Blauberg AirOne ERV \u2013 when the air becomes too dry in winter<\/h3>\n

The AirOne ERV<\/strong> uses an enthalpy heat exchanger and, in addition to heat, allows some of the indoor air\u2019s humidity to be retained.<\/p>\n

This makes the ERV version particularly attractive for new, well-sealed single-family homes where ventilation runs continuously and indoor relative humidity tends to drop too low during cold winters.<\/p>\n
