摘要

The invention relates to an apparatus which makes possible the storage of heat in a fluid reservoir of the type comprising a heat source situated outside the storage reservoir and a booster heat source which is situated inside the reservoir and is set in operation when the temperature of the fluid situated in the upper part of the reservoir becomes lower than a utilisation or desired temperature. This device is characterised in that the booster heat source (20) is placed in the lower part of the storage reservoir (14) inside a vertically arranged screen tube (24) and in that the external heat source is also connected to the lower part of the storage reservoir, but on the outside of said screen tube.
