OWR1 SMART Heating Element 2 kW – Intelligent heating element for hot water storage tanks

Product overview

The OWR1 SMART 2 kW immersion heater is a networked heating device for efficiently heating hot water in storage tanks, available in two high-quality finishes: stainless steel and copper with nickel plating. With integrated Wi-Fi and app control, the device can be monitored and operated worldwide – ideal for modern, energy-efficient households.

The device offers several operating modes (Smart, Eco, Manual, Absence, Schedule, Boost, Anti-Legionella, Frost Protection) and combines easy installation with convenient remote control. A two-year manufacturer's warranty provides added peace of mind.

Technical data

Power: 2.0 kW, Voltage supply: 230 V. Connection thread: 1 1/2" AG, installation length: 363 mm, installation type: horizontal. External regulator adjustable from approximately 10 °C to approximately 75 °C.

Safety temperature limiter: 85 °C. The device comes with a Schuko plug and is designed for easy installation. Material options: stainless steel or copper heating element with nickel plating for long service life.

Operating modes

Manual mode: The temperature can be manually adjusted within a range of 15°C to 75°C by up to ±5°C. ECO mode: Keeps the water temperature constant at 55°C to minimize heat loss, energy consumption, and stress on the heating element. Smart mode: Learns user habits and heats the water only when needed.

Schedule mode: Easily create hourly, daily, or weekly heating schedules via the app. Away mode: Maintains a minimum temperature of 10°C during extended absences to prevent damage from cooling. Boost mode: Brief, rapid heating (30 minutes) to a higher temperature, e.g., 70°C, followed by a return to the preset temperature.

Frost protection: Prevents the storage temperature from dropping below 10°C, especially useful in winter. Anti-Legionella function: Monitors the temperature and automatically activates a 30-minute heating cycle to 60°C if the temperature has not increased within 15 days.

installation && Operation

The heating element is designed for horizontal installation and is connected via the 1 1/" threaded connection.2" AG assembles. The delivery with a Schuko plug allows for easy, tool-free commissioning; however, we recommend installation by a qualified person to ensure tightness and a secure electrical connection.

Operation is via the illuminated control panel on the device and, more importantly, via the app using Wi-Fi, allowing heating schedules, modes, and boost functions to be set remotely. The external wiring of the controller allows for easy temperature adjustment within a range of approximately 10°C to 75°C.

Security && Maintenance

The built-in safety temperature limiter at 85 °C protects against overheating. The automatic anti-legionella function ensures hygienic hot water temperatures by automatically heating the water to 60 °C when needed. Frost protection prevents the contents from freezing and protects the tank at low ambient temperatures.

Regular visual inspections and, if necessary, maintenance of the heating element, as well as checking the electrical connections, extend its service life. In case of wear or deposits, replacement by qualified personnel is recommended.

Scope of delivery && Warranty

Included in the package are the heating element, the assembly and operating instructions, and a special SMART user manual for the app functions. The manufacturer provides a two-year warranty on the product.

Advantages && Areas of application

The OWR1 SMART immersion heater combines easy installation, durable materials, and flexible operating modes with modern app control—making it suitable for single-family homes, vacation apartments, weekend houses, or small commercial storage systems. The combination of energy-saving functions (ECO, Plan) and hygiene functions (anti-Legionella) is particularly advantageous.

Thanks to its compact design and Schuko plug power supply, the immersion heater is a practical solution when fast, reliable hot water and remote control are required. The choice between stainless steel and copper versions allows for adaptation to different requirements and water qualities.
