ABSTRACT:
A compact, in-line electric water heater is provided for heating water to a temperature suitable for dental operations. The heater includes a cylindrical inner tube containing an electrical heater element and a cylindrical outer tube concentrically spaced therefrom, through which water to be heated is circulated. An inlet and outlet for the water is located at one end of a chamber formed between the tubes. A control thermostat is operatively mounted on an area of the outer tube which is flattened so as to contact the inner tube and is responsive to the temperature of the outer tube. A thermal limiter is also mounted to the outer tube to function as a safety device should the control thermostat malfunction.
