Product Overview & Area of Application
The 1.5 kW Elektromet EJK mini 1500 heating rod is a compact electric heating cartridge for water heating in open and closed metal tanks. It is particularly intended for enamelled domestic hot water heaters and hot water storage tanks where an electrically insulated heating element is advisable.
This version is suitable for applications where hot water is to be reheated electrically or a storage tank is to be additionally tempered. With its 1.5 kW power class, the heating rod is primarily suitable for smaller storage tanks or tanks with a matching connection socket and sufficient minimum volume.
Technology & Equipment
The Elektromet EJK mini 1500 consists of a tubular heating element with resistance wire, an insulating structure, a metal screw-in head and a compact outer housing. The housing contains the single-phase power supply for 230 V, the heat regulator with stepless temperature adjustment, and a non-self-resetting safety temperature limiter.
The rotary knob of the heat regulator and the red indicator light are integrated into the housing cover. The screw-in connection is made via a 1 1/2 inch thread. The insulated design of the heating element electrically separates the heating element from the tank and is therefore designed for use in enamelled storage tanks with corrosion protection.
Everyday Benefits
The heating cartridge can be adjusted directly on the housing via the rotary knob and operates automatically during operation via the integrated heat regulator. As soon as the set water temperature is reached, the heating element is switched off and reactivated when the temperature falls below the setpoint.
The red indicator light shows the heating operation and makes it easier to monitor during heating. In addition, the heat regulator has a frost protection function, which is used via position 0 with a snowflake symbol and protects the tank contents against excessive cooling.
System Integration & Compatibility
The heating element is intended for metal tanks, in particular for enamelled storage tanks for domestic hot water preparation. The tank must have a suitable threaded socket for the 1 1/2 inch thread connection and be suitable for operation with an electric heating cartridge.
The installation position must be horizontal or nearly horizontal. The heating element and temperature sensor must be completely surrounded by water during operation. The EJK heating cartridge is not intended for tanks made of stainless steel or acid-resistant steel.

Installation
The heating cartridge may only be installed in a suitable metal container with a matching connection sleeve. The working position must be horizontal or nearly horizontal so that the heating element and temperature sensor are fully immersed in water during operation.
The electrical connection is made via the factory-installed plug at a suitable 230 V socket with earthing contact. The mains plug must remain accessible after installation. The connection may only be made after the container has been completely filled with water.
Notes
The heating rod must not be operated dry. With hard water, the heating element should be checked regularly for limescale deposits and cleaned if necessary, as deposits can impair heat transfer and stress the heating element.
For operation in pressure vessels, the specifications of the storage tank manufacturer must be observed. After tripping, the safety temperature limiter may only be reactivated after cooling and after checking the cause. The EJK heating cartridge is not intended for storage tanks made of stainless steel or acid-resistant steel.
