A heating system is disclosed for buildings such as dwelling houses, office buildings, commercial establishments, industrial establishments, and the like, in which it is desired to maintain a comfortable temperature level during periods when the external air temperature is relatively low. The heating system includes a solar collector mounted on the roof of the building in a manner so that it is exposed to the rays of the sun and pivotally supported and driven by a mechanism so that the solar collector can track or follow the sun as it moves from sun up to sundown. A flexible duct system interconnects the solar collector and the rooms or areas to be heated through a distribution box. The flexible duct extends through a weathertight aperture in the roof to facilitate movement of solar collector with a check valve and blower being employed in the system to circulate air and to prevent flow of warm air from the rooms into the solar collector at night which may cause condensation in the collector. The solar collector includes double glazing, a plurality of screen grids and a coil or tube assembly provided with projecting fins on opposite sides which are oriented in angular relation to the longitudinal axis of the tubes for more efficient impingement of the rays of the sun thereby providing more efficient collection of the energy of the sun. The collector is provided with an upwardly extending peripheral shield which angulates outwardly for more effective collection of the rays of the sun and also preventing cold air from moving across the surface of the glazing on the collector.
