A heating system

摘要

A water heating system has an instantaneous water heater 1 for heating potable water in a potable hot water supply line 2. The supply of potable hot water can be supplemented by potable hot water contained in a supply vessel 4 connected to the supply line 2 downstream of the boiler 1. The invention allows the combination of the advantages of heating systems having a storage vessel and heating systems having an instantaneous water heater by providing a high initial potable hot water flow rate and a continuous supply of potable hot water at a lower flow rate thereafter. <IMAGE>
