Chinese KANG is widely used as a rural home heating system in Northern China. But, the traditional thermal KANG has air pollution emission and efficiency is low. Therefore, a novel active solar heating system named as solar KANG was proposed. A dynamic numerical model was presented for solar KANG. Based on the model, heating load at a given KANG surface temperature and thermal storage characteristic of KANG were studied for a specified weather conditions. Results indicate: room air temperature swing is little at a given KANG surface temperature(25℃); The water pipe surface temperature does not exceed 40℃ to keep the surface temperature of solar KANG as constant 25℃, so solar heating water is suitable as the heating source for KANG heating system; Storage mass of KANG has great influence on room temperature, reasonable KANG mass can keep room air temperature at a thermal comfort range at night even if heating source is switched off.
