Ventilation systems from STIEBEL ELTRON
Modern ventilation technology – more than just a change of air.
Our modern ventilation systems ensure regulated air exchange without wasting valuable energy. They help maintain indoor air quality, prevent moisture damage, and provide consistent comfort throughout your home.
Why is mechanical ventilation so important?
Today’s homes are built to be airtight for energy efficiency, but this also prevents natural air changes, making mechanical ventilation essential. Older homes often face ventilation issues after insulation upgrades, as airflow through windows and doors is significantly reduced. Mechanical ventilation systems solve this problem by providing fresh air without compromising energy efficiency.
Controlled ventilation systems help prevent mold and moisture damage while reducing indoor pollutants. They offer a practical solution for maintaining a healthy and comfortable indoor environment.
In new or renovated homes, relying on windows alone for ventilation is impractical. To achieve an energy-efficient air change, windows would need to be opened four to six times daily for at least five minutes—something difficult to maintain. Mechanical ventilation systems provide a reliable, automated alternative for fresh air while conserving energy.
These systems also contribute to energy-efficient heating and cooling, ensuring a comfortable living environment year-round.
Benefits of Modern Ventilation
Modern ventilation technology improves indoor air quality, prevents moisture damage, and ensures better comfort—all while reducing energy consumption and harmful emissions.
The different ventilation systems in New Zealand
Decentralised Ventilation: Flexible and Energy-Efficient
Decentralised ventilation systems are ideal for renovations or homes with moisture-prone areas. These systems are installed as independent units in external walls and, when equipped with heat recovery, use crossflow heat exchangers to improve energy efficiency.
They work independently to remove humid air from rooms like bathrooms and kitchens. For balanced airflow, two units can be installed to ensure consistent fresh air throughout the home, with sensors that automatically adjust airflow based on humidity levels.
Central Ventilation: Fresh Air for the Whole Home
Central ventilation systems offer complete air management for the entire house. Extract air systems remove stale air from kitchens, bathrooms, and toilets, creating negative pressure that draws fresh air into living areas. Supply/extract systems with heat recovery transfer up to 90% of the heat from the extract air to the incoming fresh air, improving comfort and energy efficiency.
These systems can be installed in walls, concrete slabs, ceilings, or even as exposed ducts, making them suitable for new builds and renovations. Filtration ensures clean, fresh air while protecting allergy sufferers from dust and pollen.
Unlike extract-only systems, supply/extract systems filter the outdoor air before distributing it via ducts to living areas. This ensures a high level of comfort across the whole home and provides year-round air quality improvements.
