Abstract
A solar air and water heater comprises a solar energy collector which is crossed by a forced air flow fed by an electrically driven fan. The solar energy collector has an air inlet pipe and an air outlet pipe both connected to an air flow control device which is supported by the covering lid of a container which is filled with water. The air inlet pipe and the air outlet pipe of the solar energy collector can be connected, by means of the air flow control device, either to heat exchange means disposed within the container, so as to permit to heat the water inside the container by means of the hot air coming from the solar energy collector, or to an external circuit for direct utilization of this hot air, or to the heat exchange means and to the external circuit simultaneously, so as to permit both direct and indirect utilization of this hot air.
