ADVANTAGES

Balanced supply and extract: all air entering the building is filtered (good IAQ). Systems available that are capable of up to 95% heat recovery. Summer bypass facilites available for heat 'dumping' in warm weather. Low annual electrical energy. Multiple speed: minimum of two settings, but many systems offer up to four. Demand control allows air flow maintained at adequate levels when it is needed but possible to reduce air flow when not required. This results in energy saving without compromising the air quality
