Question: Why sometimes heating speed is felt slow


    This tends to happen in electricity peak season and time period. As the power voltage is low, the electric heater of the water heater works at a low level of power; On the other hand, heating to the set temperature makes the temperature difference becoming greater, because water temperature in the water heater cylinder is low. Therefore working time is extended, and it is felt that the heating speed slows down on the water heater.
