How does your Roof Mounted Solar Heating work?

The roof mounted solar air heater uses solar radiation to heat fresh air brought in from the outside to heat the cabin. The air drawn in by a solar powered fan. It is drawn over a special metal plate which absorbs the radiation of the sun and turns it in to heat. This warm air is then circulated in to the Log Cabin or Garden Building. The solar heater comes with an adjustable roof vent and a control switch to allow the flow of air to be controlled.
