Some details about our collector
The Twinsolar compact provides a room every hour with approx. 120 m³ of fresh air, not only when the sun shines but also on cloudy days. The electricity which is produced by solar panels, operates the integrated ventilator inside of the collector. The fresh outside air is filtered and drawn in through the heat insulated air collector, made of aluminium. In doing so, the fresh air is heated and channelled into the house via an insulated pipe. When the desired room temperature is reached, the system automatically switches off with the help of a thermostat. Even when there's no-one at home, the indoor climate is dry and healthy. Twinsolar compact is a self-sufficient system and doesn't need to be connected to the electrical grid.
