Hot water storage tank for solar heating installation

摘要

A heated water store, especially for heating by a solar radiation heating circuit, with several integrated heat exchangers, has heat exchangers (2,3) in the upper and lower regions of the store (1) connected to the solar circuit (4) which have flow through them depending on the charging state of the store and/or the temperatures in the solar circuit. They may be connected in series or in parallel. There are changeover valves with which the flow is regulated according to the charging state, the latter being determined by temperature sensors in different zones of the store. There are also thermostatic valves in the solar circuit.
