A central heating system for a plurality of separate heat users, for example houses or apartments, each of such users having a stratified heat storage vessel containing water of the circulation system as heat storage medium, characterized by means for concurrently charging heat storage vessels of a plurality of such users, and means for delivering, within a set time span after any user signals its storage vessel to approach depletion in between concurrent charging operations, primary water having a temperature that is higher than a set temperature to such user. Said means preferably include central control means and may optionally comprise bypass valve means such as (9,10) or (18,19) connecting main delivery to main return conduits. |
