Solar heating in Winter

Solar heating in Winter

When the solar ventilator is operating in the winter mode, the damper blade positioned at the upper end directs fresh air into the building.

 

This example of a ducting system in a roof cavity shows how fresh air is supplied to the solar ventilator on the roof via a filter with the help of an inline fan.

Dampers direct the air flow either to the solar ventilator and electric air heater or by-passes the solar ventilator to another air heater depending on the availability of solar heat. The first air heater stores heat from the solar ventilator and occasionally boosts the temperature to the desired level. The second air heater by-passes the solar ventilator and efficiently heats air at night time.

The amount of fresh air is pre-programmed such that there will always be a reliably warm source of fresh air flow in winter when required 24 hours of the day.
