The Importance of Mechanical Heat Recovery Ventilation

Over the last decade, homes in Melbourne are becoming more energy-efficient due to the increased standards in insulation and airtightness. Modern homes are up to twice as efficient compared to pre-millennium homes.

With such advances in thermal technologies, concerns have arisen over indoor air quality (IAQ). Studies have shown that the average IAQ in modern homes with (installed) wall vents are alarmingly poor. Long term exposure to depleted oxygen and polluted homes is likely to have negative health implications, causing illnesses such as sick building syndrome (SBS).

Studies have also shown having mechanical ventilation in spaces can help reduce the risk of being exposed to viruses.

Mechanical Heat Recovery Ventilation is required to significantly increase the IAQ in indoor spaces without keeping windows and doors open. An MHRV is cost-effective and energy-efficient in the long run.

At Advanced Climates, we recommend German-made Stiebel Eltron ventilation systems. We continually deliver top-quality installations and service by being a gold standard technical partner with Stiebel Eltron. Stiebel Eltron systems are also certified by the Passivhaus industry due to their incredibly high heat recovery rate of up to 94%.

How Does an MVHR System Work?

MHRV Systems are based on air supply, air extraction and transfer zones within the building. A heat exchanger is at the system's heart, whilst fans provide air movement. Most systems have ducting to the various rooms.

Habitable rooms are provided with fresh air while wet rooms & kitchens are extracted continually. Before the extracted air is expelled from the building, the heat in the air is recovered by the heat exchanger in the MHRV unit, and it is then transferred to the incoming fresh air distributed throughout the building.

No extracted air is re-introduced or re-cycled; thus, extracted germs and pathogens will not spread through the system. The fresh incoming air is also heavily filtered, ensuring distributed fresh, clean air.
