The heat store is used as an energy reservoir for heating or water recycling systems, and has a tank (5) with a rigid outer wall in order to store a liquid which can be heated. The tank has connections (7,8) for pipes to supply and draw off the heat-carrying liquid, and has an insulating jacket (15) which is arranged around its outside, and which is made from a material which retains its shape. A thermometer is fitted in order to sense the temperature of the liquid. A cavity is formed between the outer wall of the tank and the insulating jacket, and acts as a channel (12) for a fluid whose flow can be controlled in order to prevent the heat-carrying liquid from overheating. The channel has an inlet (I) and an outlet for the fluid flow, and the tank may have at least two zones with different temperatures. USE/ADVANTAGE - The heat-carrying liquid is prevented from overheating.
