100-liter domestic hot water tank with integrated OWR1 heating element 3 kW – compact hot water solution
Product description hot water tank
The 100-liter domestic hot water tank ETWS is designed for the central and safe heating of service water. A highly efficient heat exchanger transfers heat from solar thermal systems or a boiler to the domestic water, while the high-quality enamel coating and a large magnesium sacrificial anode ensure corrosion protection inside.
The rigid polyurethane foam insulation reduces heat losses and ensures good energy storage. Optionally, a 1 1/2" electric heating element can be retrofitted or combined to enable heating, e.g., via a photovoltaic-supported electric heating system.
Advantages of the 100-liter tank
The unit offers an attractive price-performance ratio and high hot water comfort for a typical demand of 100–180 liters. The built-in heat exchanger operates very efficiently, a circulation connection is available, and connections for the heating circuit and service water are standardized.
Corrosion protection through enamel and magnesium anode as well as robust insulation ensure longevity. The compatibility with solid fuel, pellet, and combination boilers as well as solar thermal systems makes the tank versatile.

OWR1 Heating Rod 3 kW Product Overview
The OWR1 is a compact electric heating rod with 3.0 kW output at 230 V, designed for direct heating of domestic hot water and service water tanks, boilers, and buffer tanks. The 1 1/2" connection thread and installation length of 360 mm allow easy integration into many standard containers.
The heating rod features an externally adjustable controller for temperature setting and an integrated safety temperature limiter for additional overheating protection. Delivery includes an assembled Schuko plug for easy electrical connection.
Technical Data Heating Rod
Output 3.0 kW; power supply 230 V; connection thread 1 1/2" male; installation length 360 mm; installation type horizontal; adjustable from approx. 20 °C to approx. 70 °C; safety temperature limiter 85 °C; delivered with Schuko plug.
Installation and Safety
The heating rod is screwed horizontally into the tank via the 1 1/2" thread; before installation, the power supply must be switched off and the sealing surfaces checked. The externally mounted controller allows comfortable settings, and the safety temperature limiter prevents overheating.
It is recommended to carry out the installation according to the instructions and to consult an electrician if there are any uncertainties. Regular visual inspections and checking of seals and electrical protection extend the service life and increase operational safety.
Areas of Application and Combinations
The combination of a 100-liter tank and the OWR1 heating rod is suitable for private households as well as smaller commercial applications, either as a complete solution or as an addition to existing systems. The tank can be operated with solar thermal systems, solid fuel and pellet boilers, as well as combination boilers, and the electric auxiliary heating enables flexible operating modes, for example in conjunction with photovoltaics.
