Performance evaluation of a solar heated slab residential heating system

The paper summarizes the results of an experimental and analytical study to measure and characterize the performance of a solar slab heating system. This hybrid design, frequently referred to as an active charge/passive discharge system, combines liquid cooled solar collectors and a concrete slab as the energy storage/heating source. In addition to experimental energy balance data for a full-sized test resicence, a summary and preliminary results for an analytical model of the basic system are presented.
