摘要： A heat storage apparatus includes a tank containing a heat storage medium and having an upper region and a lower region for holding the heat storage medium at respective temperatures above and below atmospheric temperature. To reduce heat losses and increase flexibility of use, an intermediate region having heat storage medium is maintained in the tank between the upper and lower regions at a temperature between the upper and lower temperatures. The desired temperature of the intermediate region is maintained by heating or cooling its heat storage medium, for example by use of an otherwise unused low-grade heat source.
