ABSTRACT
In highly efficient houses, the need for thermal storage is often short term. In such instances, water is a very efficient storage medium for both space heating and hot water production.
Heat can be stored in three ways:
1 Sensible heat storage. The storage is based on the temperature change in the material. The unit storage capacity (J/g) is equal to heat capacitance x temperature change. Possible ‘sensible heat’ storage media are liquids (typically water) and solid materials (typically soil and stone).
