Product Overview & Area of Application
The 2 kW 230 V heating element is an electric screw-in immersion heater for the direct heating of water in suitable water heaters, storage tanks, buffer tanks, or heat exchangers. The MB 2000 OWR1/230V variant is designed for the 1 1/2-inch version and is typically suitable for tanks with a capacity of approx. 80 to 140 liters.
The GEMA heating element can be used for supplementary hot water preparation during the heating season or for independent heating outside the heating season, provided that the tank, electrical installation, installation space, and operating conditions match the selected variant.
Technology & Equipment
The 2 kW version is based on the OWR1 design for 230 V. The heating element features an integrated thermostat, a connection housing, and an operating indicator light. The temperature control range is approx. 20 to 70 °C.
The installation length L is 385 mm. The thread connection is designed as 1 1/2 inch / 6/4 inch. According to the OWR1 instructions, the 230 V version has an IP44 protection rating and an integrated overheat protection.
Everyday Benefits
Thanks to the integrated thermostat, the desired water temperature can be set directly on the heating element. This makes the electric auxiliary heating particularly straightforward when simple, directly acting heating is required in a suitable tank.
The 230 V version is intended for applications with a suitable Schuko/safety earth connection. Operation is only permitted with the heating element fully surrounded by water, which makes professional installation and commissioning particularly important.
System Integration & Compatibility
The heating element is intended for suitable storage tanks, water heaters, buffer tanks, or heat exchangers with a matching 1 1/2-inch connection. Before installation, the threaded connection, socket length, installation length, installation space, and the approval of the respective tank or system manufacturer must be checked.
The maximum socket length for the OWR1 version is 55 mm. Operation is intended only for water and is carried out in a horizontal installation position with the connection cable pointing downward.
