Abstract (en)
[origin: EP1070922A2] The heating device has at least one heating element (30), at least one heat transfer element (20) in thermally conducting connection with the heating element and fluid, a common temp. monitoring device (50) for the heating element and for the fluid and a controller. The temp. monitoring device is connected to the controller and delivers an output signal to it depending on the temp. variation in the heating element and/or heat transfer element. An Independent claim is also included for a method of controlling a heating device for fluids.
