Abstract
An appliance for heating fluid includes a reservoir for holding the fluid during use. One or more ceramic heaters mount with the reservoir to heat the fluid. The heater includes electrically resistive traces thick-film printed on a substrate. The heaters optionally mount with a heat transfer element having a relatively large surface area. The heat transfer element typifies a conductive element, such as an aluminum plate of forged aluminum. The plate has cavities to retain the heaters or sections fitted about heaters. Holes through a thickness of the plate induce turbulent fluid flow as the fluid freely passes there through during use. Heater control and mounting are still other aspects of the technology.
