The base solar systems and base heat pump systems are also covered, before going into the hybrid systems. Three special types of solar-assisted heat pump systems such as parallel, series and dual systems are included,and closely examined in various aspects. Their advantages over the base solar energy systems and the base heat pump systems and also over one another are stated. The efficiency of each system and the ways to improve the efficiency is discussed.30 cm.Heat pumps.Solar heating.Solar space heating.Solar water heaters.x, 91 leaves;
