MB 3000 OWR1/230V AISI - Stainless steel electric heating element (3 kW)

Efficient, durable and corrosion-resistant

The MB 3000 OWR1/230V AISI is a powerful 3 kW electric heating element made from premium stainless steel (AISI). Its corrosion-resistant construction makes it highly suitable for continuous operation in boilers, buffer tanks and solar thermal systems, even under varying water conditions.

Stepless temperature adjustment

The integrated rotary dial allows smooth temperature control between 20 and 70 °C. Built-in overheat protection automatically shuts down the heater when temperatures reach between 80 and 98 °C, ensuring system safety and stable performance.

Fast plug & play installation

With its 1½" male thread and plug & play design, the heater can be installed quickly in both new and existing systems. Its IP44 rating provides excellent resistance against splashing water and dust, making it suitable for technical rooms and compact storage installations.

Why stainless steel (AISI)?

Compared to the copper version, this stainless steel model offers superior corrosion resistance and reduced limescale buildup. This results in longer service life, more stable performance and lower maintenance requirements—especially in systems with hard or fluctuating water quality.
