Thick film heating elements are very suitable for heating water. Since the thermal mass of the elements is low, nearly all generated heat will be dissipated into the water.
This results in an extremly high efficiency. Water side of the heating elements is nice and shiny linished.
An Otter Controls thermal protector guarantees safe operation in any condition. The control also provides the electrical interface to a 360 degree rotatable power base connector.
Power ratings up to 3.1kW are possible on a disc diameter of 120mm.
