Description

100-liter domestic hot water storage tank ETWS with OWR1 SMART 2 kW heating element (WIFI)

Product description of the hot water storage tank

The ETWS 100-liter hot water storage tank is a central storage unit for the safe and efficient heating of domestic hot water. It is suitable for combination with solar thermal systems, boilers, or solid fuel heating systems and, with its internal heat exchanger, offers reliable hot water comfort for households.

The design relies on durable materials and protective measures such as a high-quality enamel coating and a large magnesium sacrificial anode to prevent corrosion and extend the lifespan of the storage unit.

Technical data – Hot water storage tank

Volume: 100 liters; Heat exchanger surface area: 1.2 m²; Heat exchanger capacity: 5.27 liters. Connection dimensions: Heating flow/return 3/4" AG, Supply/Return Domestic Water 3/4" AG, Circulation 3/4" AG, Magnesium anode 1 1/4" IG, connection for electric heating 1 1/2" IG.

Max. operating temperature storage tank 95 °C, Max. operating pressure storage tank/heat exchanger 6 bar, Power loss approx. 28 W. Dimensions with insulation Ø 625 x H 770 mm, Empty weight 64 kg.

Special features of the storage unit

The storage tank features a highly efficient heat exchanger, a circulation connection, and a retrofittable fitting for a 1 1/2" Electric heating element. The thermal insulation consists of densely foamed polyurethane foam (PUR) for low heat loss.

Corrosion protection is ensured by an internal enamel coating and a built-in magnesium sacrificial anode, which increases the service life, especially in the case of changing water qualities.

OWR1 SMART heating element 2 kW – Overview

The OWR1 SMART 2 kW immersion heater is a networkable electric immersion heater for supplementing hot water storage tanks. It is available in stainless steel or with a copper heating element and nickel plating and offers Wi-Fi connectivity with app control for remote monitoring and operation.

With a power output of 2.0 kW at 230 V, a connection thread of 1 1/2" With a length of 363 mm, the heating element is specifically designed for horizontal installation and for easy commissioning with a Schuko plug.

Operating modes of the SMART heating element

The heating element offers several modes: Manual mode for direct temperature setting, ECO mode (constant 55 °C) to protect the heating element, intelligent mode that learns user habits, and schedule mode for time control via app.

In addition, absence mode (minimum temperature 10 °C), boost mode (short-term rapid heating) and frost protection and anti-legionella functions (automatic 30-minute heating cycle to 60 °C if required) are available.

Technical specifications – OWR1 SMART heating element

Power: 2.0 kW; Voltage: 230 V; Installation type: horizontal; Installation length: 363 mm; Connection thread: 1 1/2" AG; Externally adjustable regulator from approx. 10 °C to approx. 75 °C. Safety temperature limiter at 85 °C.

The heating element comes with a Schuko plug, communicates with an app via WLAN and is available in robust material variants that ensure a long service life and corrosion resistance.

Installation and operation

The heating element is connected to the existing 1 1/2" The storage unit is pre-assembled and designed for horizontal installation. Thanks to the Schuko plug, commissioning is possible with minimal tools; however, installation and electrical connection by qualified personnel are recommended to ensure leak-proof performance and safety.

Operation is via the illuminated control element on the device or conveniently via app via WLAN, where heating schedules, operating modes and boost functions can be set up and monitored.

Safety and maintenance

The built-in safety temperature limiter (85 °C), frost protection, and automatic anti-legionella system ensure safe operation and hygienic hot water temperatures. Regular visual inspections and occasional maintenance extend the service life of the heating element and the storage tank.

In case of wear or deposits on the heating element, replacement by qualified specialists is recommended; the magnesium anode in the storage tank should be checked periodically and replaced if necessary.

Scope of delivery and warranty

Included with the heating element: heating element, installation and operating instructions, and special SMART operating instructions for app functions. The OWR1 SMART heating element comes with a two-year manufacturer's warranty.

The hot water storage tank is supplied including insulation and pre-assembled connections; electrical connection and final installation should be carried out by a qualified professional to ensure warranty conditions and safe operation.

Advantages and areas of application

The combination of a 100-liter storage tank and SMART heating element offers flexible hot water comfort, energy-saving functions, and remote controllability. It is suitable for single-family homes, vacation apartments, weekend houses, or small commercial storage systems, especially when solar thermal or photovoltaic integration is planned.

Further advantages include the attractive price-performance ratio, low heat losses due to PUR insulation, easy retrofitting of an electric heating element, and extensive protection functions against corrosion and Legionella.
