Our Passive Ventilation with Heat Recovery (PVHR) system is designed for continuous Twenty-four hour ventilation, for the supply of fresh air and the extraction of stale air independently, into and from each area of the home.
Ventive S: single PVHR unit retrofitted into existing chimney stacks, replacing the chimney pot with a cowl and cassette that features an innovative, patented and incredibly efficient heat exchanger.
Ventive S+ uses the same innovative and patented Passive Ventilation with Heat Exchange technology as Ventive S, but does not rely on chimneys being present within the building. Utilising an integrated duct system, Ventive S+ fits neatly between rafters and seals to the existing roof finish, allowing easy installation of multiple or single units.
Ventive uses a combination of air buoyancy and wind (active from very low wind speeds) to create a flow of air within the interior of the building, ensuring greater than minimum standards of air quality are achieved and maintained.
Ventive systems are perfect for retrofit and new build projects.
