This paper proposed an innovative design for in-door electrical heating system that uses commercially available carbon fiber tape (CFT). The design of the heating panel, layout and the construction of a prototype were presented with experiment results. The heating panel was made of three carbon fiber tapes and embedded in cement mortar. Each CFT was 50 mm wide with a spacing of 200 mm. Several experiments were conducted to examine the performance, temperature variation with time and location, and energy consumption of the proposed system. The experiment result has shown that the heating system performs satisfactorily and is heated up quickly with an average speed of 1.83 °C/min. The temperature gradient in the vertical direction is much larger than that in the horizontal direction. The electrical resistance of the CFT is stable, and the reflective membrane and insulation board are effective in reducing the heat transfer towards the bottom. The automatic temperature control device can reduce the energy consumption significantly.
