Teagan, W

In an integral storage collector solar heating system, water heated in a conventional hot water heater is first preheated in an integral storage collector. The storage collector includes a heat storing medium, preferably clean water, in a storage tank. Water to be heated is forced by line pressure through heat exchange pipes immersed in the heat storing water. The heat of fusion of the storing water prevents freezing of the line water. To preclude excessive pressure in the heat storage tank with high temperatures of the heat storing water, a heat pipe is provided to act as a large heat leak at about the vaporization temperature of the water. Also, a pressure relief valve is provided. The system avoids freezing and contamination of the water and does not require temperature control circuitry or a pump.
