Solar-Venti is a unique and low running cost Positive Input Ventilation system. Unlike our Awenta range, the PIV is only designed to draw in fresh air to the property, relying on existing ventilation openings to force out any stale or moist air from the home. This strategy doesn’t work for new build homes that are built to airtight, well-insulated standards as there will be limited passive openings. The benefit of the Solar Venti is its ability to heat the air through solar radiation before it enters the home. On a sunny day whether summer or winter, the Solar Venti can deliver heated air at up to 22 degrees. During sunny winter days, this can reduce the burden on your heating systems and should help to keep the ambient temperature within the home at a higher level.
