This is the final report of the work carried out on the project "Modelling of Thermal Storage for Solar Heating Systems". The results: system performance is most strongly influenced by the collector quality and the heat emitter distribution circuit, less so by storage mode, storage material, phase change or water storage, and storage capacity. A comparison of thermal performance between the various storage modes and materials indicates that there is little improvement to be gained by an alternative storage device compared with a fully mixed water store with a minimum useful temperature of some 25 degrees C and a parallel auxiliary system. The state-of-the-art in the derivation of a universal design method is described. Further work is needed to include combined space heating and domestic hot water. By way of outlook, it is concluded that improvements in both the collector quality and emitter performance should have the highest priority and that research is still needed on characterizing storage devices (test procedures and cost reduction).
