Abstract
A solar hot water heating system, utilizing preferably a gas-liquid, phase change medium in the collector, employs one heating and storage tank above the collector and a preheating and storage tank below the first tank and preferably also below the collector. A cold water source feeds the inlet of the preheating tank which has its outlet connected to the inlet of the heating tank. The hot water outlet of the heating tank not only supplies heated water where needed but has a connection for recirculating surplus hot water to the inlet of the preheating tank by means of a pump which is activated and deactivated by a switch sensitive to the temperature of the medium.
