The objective of this study is to compare the thermal performance of various radiant floor heating control methods in apartment buildings. For this, the room temperature and floor temperature stability of various water flow control methods were compared th개ugh the computer simulations The results show that on/off Bang-Bang control is less accurate than variable flow control, but on/off pulse-width modulation has the same performance as variable flow control. The outdoor reset+on/off Bang--Bang control is more stable when the heating curve is properly set through the fine tuning. Outdoor reset+pulse-width modulation is much more stable than the outdoor reset+on/off Bang Bang control.
