This has the advantage of allowing high temperatures, far exceeding the ambient temperature, to be achieved. A disadvantage is that the heat from the ambient air cannot be utilized, even when there is no direct solar radiation. According to the invention, this disadvantage is overcome by providing the housing containing the actual collector, through which the heat transfer medium flows, with at least two openings. These openings are tightly closed by flaps or similar devices when direct solar radiation is sufficiently high, but can be opened when needed, i.e., when direct solar radiation is low, allowing air to flow over the actual collector, either by natural draft or driven by a fan.The opening and closing of the flaps or similar devices, and the operation of any fan (if present), are controlled by a system that calculates and compares the heat gain from direct solar radiation and airflow, and reacts accordingly by switching the fan on or off and opening or closing the flaps. A further control system, depending on the temperature of the heat transfer medium and the hot water in the storage tank, as well as the heating demand, determines whether the heat transfer medium is used to further heat the hot water in the storage tank or to power a heat pump.
