Heater for fresh water supply in aircraft has tubular feed pipe with electrical heating element between insulating layers

摘要

The heater for a fresh water supply in an aircraft has a feed pipe (25) with an electrical heater (1) to provide a preset adjustable temperature of the water flow. The heating effect is reduced to prevent local overheating when flow is reduced or stopped. The feed pipe can be made of different tubular material layers to define an electrical heating element, with a heating element between two insulating layers.
