The electric heating belt of the water pipe is actually the electric heating cable, but the temperature of the water pipe is relatively low, and the highest temperature is 75 ° C, and the maximum power is 25 w/m. Many people have misunderstood that if the heating belt is 1 meter long, the working hour is 25w. In fact, the average is up to 10w. The longer the power is, the smaller the power is. The new heating belt changes with the temperature. Therefore, the heating time is higher. The smaller the power, the smaller.
