Abstract
The invention relates to an apparatus for heating water by solar energy, including a container made from a plastic film or sheeting for the water to be supplied to consumers, having a cold water inlet opening preceded by an inlet valve and having a withdrawal opening, wherein the top of the container is transparent and the bottom is dark in color. To further develop a known apparatus of this type such that water can be withdrawn even for relatively large-scale needs and it can be connected to an installed water system, it is provided that the outlet opening is followed by a pump and a check valve, that the inlet valve is electromagnetically actuatable, and that a sensor for measuring the instantaneous water temperature and an adjusting device for adjusting the desired temperature of the water to be supplied are connected to the inlet valve. The higher the instantaneous water temperature, the more cold water the inlet valve admits into the container.
