Abstract
A water heater insert device positioned within an electrical showerhead or as a standalone liquids heating device. The water heater insert optimizes heat transfer by channeling water through a channel of a spiral or zigzag form where a deployed heating element supplies thermal energy. The channel maximizes water contact while minimizing the space. A temperature limiter adds protection against scalding.
