The present invention comprises heat-storage means to store heat in a tank of liquid, and back-up heat means. The back-up heat means comprise more than one source of heat, which can produce back-up heat and heated liquid at various temperatures (for example, LOW and HIGH-temperatures). And, there are more than one heat-use means (for example, LOW and HIGH-temperature heat use means). And, there are a number of means to conduct the flow of the heated fluid among the heat-storage means, the back-up heat means, and the heat-use means.
