In this study, an experimental data based exergo-parametric study of hybrid heating systems is carried out. Experiments are conducted in a special test chamber that was constructed and operated according to ANSI/ASHRAE Standard 138. Radiant floor heating and convective heating combinations at different splits were investigated for minimum exergy destruction and energy consumption while thermal comfort was maintained. According to the results, optimal radiant system to total system capacity ratio is about 0.6.
