120-liter domestic hot water tank with OWR1 SMART heating element 3 kW (Wi-Fi)
Product overview
The 120-liter domestic hot water tank combines a highly efficient hot water storage tank with the smart heating solution OWR1 SMART heating element 3 kW. The system is suitable for central hot water preparation, can be coupled with solar thermal, boilers, or photovoltaics, and offers additional operating convenience and energy management through the Wi-Fi app control.
Features of the domestic hot water tank
The tank features an integrated heat exchanger with a surface area of 1.4 m² and a capacity of 6.1 liters, a circulation connection, and a connection for a 1 1/2" electric heating element. The interior is coated with high-quality enamel and additionally protected against corrosion by a large magnesium sacrificial anode.
Technical data of the tank
Volume 120 liters, maximum operating temperature of the tank 95 °C, maximum operating pressure of the tank and heat exchanger 6 bar. Connections for flow/return of the heating system as well as domestic hot water and circulation are 3/4" male thread, connection for magnesium anode 1 1/4" female thread. Heat losses amount to approx. 32 watts; dimensions with insulation: Ø 565 x H 1045 mm; empty weight 71 kg.
Features of the OWR1 SMART heating element
The OWR1 SMART heating element delivers 3.0 kW at 230 V and is designed for horizontal installation. It has a 1 1/2" male thread connection, a durable nickel coating, and is supplied with a Schuko plug, which simplifies installation. An adjustable controller covers temperatures from approx. 10 °C to approx. 75 °C, supplemented by a safety temperature limiter at 85 °C.
Operating modes and app functions
Multiple operating modes such as Manual mode, ECO, Intelligent mode, Schedule mode, Away mode, and Boost enable flexible control. The integrated Wi-Fi function and the app allow you to create schedules, control the temperature remotely, and monitor the device status from anywhere.
Installation & Assembly
The heating element is mounted horizontally via the 1 1/2" external thread; thanks to the included Schuko plug, no fixed wiring is required. Note the installation length of 345 mm and ensure sufficient space in the installation area. Detailed assembly and operating instructions are included.
Safety, Hygiene, and Protection Functions
For safe operation, an integrated safety temperature limiter, frost protection function, and the anti-legionella routine are provided: If no temperature increase to 60 °C is registered for 15 days, a 30-minute heating cycle starts automatically. The combination of enamel coating and magnesium anode protects the interior of the tank from corrosion.
Advantages and Areas of Application
The system offers an excellent price-performance ratio, high hot water comfort for households with a consumption of around 100–180 liters, and flexible connection options for solid fuel boilers, pellet boilers, combination boilers, wood gasification boilers, or solar thermal systems. The smart heating element control optimizes consumption and increases user comfort.
Scope of Delivery & Warranty
The scope of delivery includes the OWR1 SMART heating element, assembly and operating instructions, as well as a special SMART operating manual for the app. The manufacturer provides a two-year warranty on the heating element; for information on the warranty for the tank, please refer to the product documentation.
Compatibility and Practical Notes
The tank can be combined with solar systems, heating boilers, and photovoltaic systems. A 1 1/2" connection is available for retrofitting a heating element. During installation, ensure compliance with local regulations, adequate protection, and use of the designated connections for circulation and the magnesium anode to ensure a long service life and safe operation.
