Product Overview & Application Area
The GEMA electric heating element 2.5 kW is a screw-in heating element for electric auxiliary heating of water in suitable storage and tank systems. It is typically used when a hot water or buffer tank is to be electrically reheated or supplemented as an additional heat source.
The heating element is intended for water in open or closed tanks. Thanks to the integrated insulation separation, it is particularly suitable for appropriate storage applications where a professionally integrated electric auxiliary heater is required.
Technology & Equipment
The electric heating element is designed as a screw-in heating element with tubular heating elements and a sensor protection tube. The connection housing contains the temperature controller, a safety temperature limiter, and an integrated indicator lamp for visual inspection of the operating status.
The temperature can be set via the external controller. For this power class, the 230 V connection is particularly relevant; for versions up to 3 kW, the voltage of 230 V must be taken into account.
Everyday Benefits
The GEMA electric heating element 2.5 kW enables electric auxiliary heating directly in the storage tank and can thus support hot water preparation or storage reheating. Operation is carried out via the integrated temperature controller on the connection housing.
The integrated indicator lamp facilitates monitoring of the operating status. For permanently reliable operation, attention should be paid to water quality, limescale formation, and professional commissioning.
System Integration & Compatibility
The electric heating element is installed via a G 1 1/2" screw-in thread into a suitable storage socket. Before selecting, the connection size, installation position, installation space, operating pressure, and electrical connection conditions should be checked against the existing storage tank.
The integration is intended for suitable storage and container systems in which the heating element is sufficiently surrounded by water during operation. The electrical wiring must match the existing system and be carried out professionally.

Installation
The heating element is designed for horizontal installation in a suitable storage sleeve. Before installation, the appropriate connection size, the available installation space, and the electrical connection option must be checked.
The electrical connection may only be carried out by an approved electrician. Before switching on the power, the tank must be completely filled with water, and the wiring must be checked according to the wiring diagram.
Notes
During operation, the heating element and the sensor protection tube must be sufficiently surrounded by water. Dry operation, unsuitable installation position, incorrect voltage, or heavy scaling can impair the function.
Note on the electrical version: For versions up to 3 kW, a voltage of 230 V must be considered. Depending on the lime content of the water and the operating conditions, regular cleaning or descaling may be required.
