The heating system has a solar collector for heating an air stream which is subsequently fed through a heat storage mass for storing heat transferred from the warm air. The same storage mass can also be used to store heat obtained from off-peak electrical heating. A press reduction is provided in the storage mass by a suction fan to draw air from the collector or from the locality through it, so that it is heated by the stored heat for circulation to the space heating circuit. Pref., the solar collector has spaced superimposed panels defining an air circulation space to which the air is supplied at the bottom and exits at the top. Two hydraulically operated valves control the air circulation through the storage mass in dependence on the level of received solar energy. The system is designed for economy and max. energy utilisation. |
