Heat reservoir i.e. stratified storage, for heat supply from solar collectors to solar heat exchanger for heating e.g. room, has feed pipes and return pipes with parts, which are provided with thermal insulation and run at reservoir

摘要

The reservoir (1) has feed pipes (21, 31, 41) and return pipes (22, 32, 42) with parts provided with thermal insulation, where the parts run at the reservoir. The thermal insulation of the feed pipes and the return pipes is interrupted for direct accommodation of heat from reservoir water or deliver of heat to the reservoir water by a limited region. Solar heat is supplied to the reservoir by a solar heat exchanger (2) arranged at a lower end of the reservoir. A funnel shaped covering (23) is oriented with a larger lower opening to bottom of the reservoir.
