ABSTRACT:
A heater apparatus includes a flat-shaped heater portion attachable to a vessel such as a water tank, and a controller for controlling the heater portion. The heater portion includes a flat heater, a first temperature sensor for detecting temperature of the flat heater, and a second temperature sensor for detecting temperature of what is contained in the vessel or water tank. The controller keeps the temperature constant inside the vessel in accordance with the temperature detected by the second temperature sensor. If the rate of rise in temperature detected by the first temperature sensor is faster than is deemed normal, the controller stops current flowing to the flat heater.
