Product Overview & Area of Application
The GEMA electric heating element 12 kW is a screw-in heating element for direct water heating in suitable storage tanks and containers. This version belongs to the WPI series and is specifically intended for enamelled tanks, for which the appropriate installation situation, the available voltage and the operating pressure must be checked before installation.
With its 12 kW version, the heating element is suitable for applications where a higher electrical heating output is required via a three-phase 400 V connection. It is used in water and requires that the heating element and the sensor protection tube are completely surrounded by water during operation.
Technology & Equipment
The electric heating element is designed as a screw-in heating element with three U-shaped tubular heating elements and a sensor protection tube. The compact screw head integrates the temperature controller, safety temperature limiter and indicator light, allowing operation and monitoring directly on the device.
The integrated electrical isolation is intended for use in enamelled tanks. The sheath material Incoloy 825, the protective cap made of ABS V-0 and the IP54 protection rating support a robust technical design for the intended area of application.
Everyday Benefits
The temperature is set via the integrated temperature selector and can be adapted to the respective requirements in the storage tank. The red indicator light clearly shows the operating status and facilitates monitoring in the technical room.
For permanent operation, water quality, water hardness and operating temperature are important factors. With calcareous water, adjusted temperature settings and regular professional checks are advisable to reduce deposits on the heating element.
System Integration & Compatibility
The heating element is installed horizontally in a suitable 6/4-inch or G-1-1/2-inch socket. When selecting, particular attention must be paid to the installation length, unheated zone, socket position, available installation clearance, operating pressure, and existing electrical connection.
According to the documentation, the 12 kW version is designed for 3 x 400 V. The electrical design, fusing, cable sizing, and connection must match the system and be checked by an approved electrician.

Assembly
Assembly must be carried out exclusively horizontally into a suitable, flat and sealable socket. For the 12 kW version, an installation length of 900 mm as well as additional assembly clearance in front of the socket must be taken into account.
The unheated area is approx. 120 mm from the sealing surface. This area is important when selecting the heating element, as it determines from which position the heated zone begins in the storage tank. An open-end wrench SW 60 is provided for tightening.
Notes
Before commissioning, the tank must be completely filled with water and vented. Dry running, operation without sufficient water level, or operation outside the technical limits are not permitted.
Assembly, electrical connection and commissioning may only be carried out by an approved electrician. In the event of malfunctions, leaks, visible damage or unusual operating behavior, a professional inspection is required.
