Product Overview & Application Area
The GEMA electric heating element 3.0 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.
This version is particularly intended for suitable enameled storage tanks and containers. Thanks to the integrated insulation separation, the temperature controller, and the safety temperature limiter, the heating element is suitable for technically clean storage applications with professional electrical connection.
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 connection housing contains the temperature controller, safety temperature limiter, and a red indicator light for visual inspection of the operating status.
The temperature can be set via the external controller. For the 3.0 kW version, a 230 V connection is possible and particularly relevant in the shop; the final electrical design must match the system and be checked by a qualified electrician.
Everyday Benefits
The GEMA electric heating element 3.0 kW enables electric auxiliary heating directly in the storage tank and can thus support hot water preparation or storage reheating. Operation is via the integrated temperature controller on the connection housing.
The indicator light facilitates visual inspection in the technical room. For long-term reliable operation, water quality, scale formation, installation position, and professional commissioning should be taken into account.
System Integration & Compatibility
The electric heating element is installed via a G 1 1/2" male thread into a suitable immersion heater boss. Before selecting, the connection size, installation position, installation space, operating pressure, water hardness, and electrical connection conditions should be checked against the existing tank.
The integration is intended for suitable open or closed water vessels. During operation, the heating element and the sensor protection tube must be permanently and sufficiently surrounded by water.

Installation
The heating element is designed for horizontal installation in a suitable storage sleeve. Before installation, the sleeve, free installation length, installation clearance, sealing surface, and electrical connection options must be checked.
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 in accordance with the circuit diagram and applicable electrotechnical regulations.
Notes
During operation, the heating element and sensor protection tube must be sufficiently surrounded by water. Dry operation, unsuitable installation position, incorrect voltage, or heavy scaling can impair function.
For the 3.0 kW version, a 230 V connection is possible. For higher power classes, a correspondingly designed electrical installation is required; the final design depends on the nameplate, system planning, and on-site inspection.
