More Information
Summary:The heater includes a resistance heating element comprising a resistance heating wire having a pair of terminal ends connected to a pair of electrical connectors and encapsulated with a thin electrically insulating polymeric layer. The resistance heating wire is capable of maintaining a fluid initially heated by a primary heat source substantially at the desired use temperature. A first connecting body is configured to couple to the section of piping containing the fluid. The connecting body includes a fluid inlet port, a fluid outlet port, a fluid passageway defined between the fluid inlet and outlet ports, and an electrical connection port. The resistance heating element is disposed at least partially within the fluid passageway and at least a first one of the terminal ends is coupled to a respective one of the pair of electrical connectors through the electrical connection port.
