ABSTRACT:
A fluid heater including a reservoir, an inlet-conduit assembly and an outlet conduit. The reservoir contains fluid and includes heating elements. The inlet-conduit assembly is mounted to the reservoir and has an inlet-aperture and is in communication with the reservoir at an opposite end. The outlet conduit is mounted to the reservoir and is in communication with the reservoir at one end and has an outlet-aperture at an opposite end. A fluid-flow detector assembly is mounted to one of the inlet-conduit assembly and outlet conduit. A heating element modulator is mounted to the inlet-conduit assembly. The heating element modulator is connected to the heating elements. A thermal sensor is mounted to at least one of the inlet-conduit assembly, reservoir and outlet conduit. A controller is connected to the heating element modulator, to the fluid-flow detector assembly and to the thermal sensor. The fluid enters the inlet-conduit assembly through its inlet-aperture causing the fluid-flow detector assembly to instruct the controller to activate the heating elements via the heating element modulator. The fluid into the reservoir to be heated by the heating elements and out of the reservoir into the outlet conduit towards the outlet-aperture.
