Breathing easier, sleeping bettery
We originally purchased a Ventis system to eradicate pollen and mould from our house to improve our asthmatic son's quality of life. The Ventis system has very effectively provided that.
An added benefit was the heating/cooling provided by circulating air from our ceiling cavity. After adding vents to the soffit on the shady side of our house, heating/cooling benefits have increased exponentially and the effectiveness has expanded well beyond the peak Spring/Autumn periods of the standard product.
Current daytime temperatures are often in the 30's, but The Ventis system is efficiently circulating afternoon/nighttime cooler air throughout the house from outside, providing a great environment for a good night's sleep.
As a consequence, heating and cooling costs have dramatically decreased, with the need for aircon reduced to a couple of hours per day on only the hottest of sumer days
