Abstract: We have investigated the distribution of temperature in the water heated by infrared radiation from two types of ceramic heater (type A, B) having individually different spectral radiation characteristics as shown in Fig. 1. The results are as follows. ① The energy loss by evaporation during our experiment was less than 1% and it was negligible compared with the energy contributed to the temperature rise of the water for both type A, B. ② The ratio of the energy contributed to the temperature rise of the water to the emitted radiation energy for type B was about 84% of that of type A and type A had good efficiency for heating of the water than type B. ③ The results of the calculation by finite difference method (explicit scheme) for one-dimensional heatconduction equation in consideration of Lambert absorption coefficient of water showed some different tendency to the experimental results. The reason is not yet clear and the more studies are needed.
