System of solar heat storage with evacuated tubular solar collectors, without use of a pressure booster when the system is connected to the water supply network

摘要

The heater has a metallic heat conductor tube (3) that lies in the hot water of a tank (1). The tube has an inlet connected to a water supply system, and an outlet connected to a sanitary system. The water from the water supply system circulating in the tube gradually recovers by heat exchange, the heat accumulated in the tank water by solar collectors (2).
