The economics of a passive solar heating system(PSHS) with the pebble bed heat storage was evaluated, and the applications of the PSHS were analyzed, in this study. The results are as folows: The heating load, solar heat gain, and stored heat/year of the PSHS in the solar house model were found to be 10,778MJ, 3,438MJ, (conventional coal heating system, CCHS), which uses coal, were found to be USD1.60/year and USD60.90/year, respectively, and the yearly expenses of the PSHS were found to be 38 times less than those of the alternative heating system(CCHS). If it will be supposed that the life cycle of the passive solar heating system, according to the results of the LC analysis in the two systems, is 40 years, the total expenses for the life cycle of the PSHS and the CCHS will be USD1,431.50 and USD2,740.00, respectively. The period for the investment payback of the PSHS is six years.
