100-liter domestic hot water storage tank with 2 kW heating element – Reliable hot water heating
Product overview
The 100-liter hot water storage tank ETWS is a modern solution for central hot water heating in homes and commercial applications. It offers optimal hot water comfort for a demand of 100 to 180 liters and impresses with its excellent price-performance ratio.
The combination of a highly efficient heat exchanger, integrated connections and robust safety features makes this storage tank a first-class choice for safe and energy-saving hot water preparation.
Efficient hot water heating
Inside the storage tank is a high-performance heat exchanger that efficiently transfers the thermal energy from solar thermal systems or boilers to the domestic hot water. This ensures fast and reliable hot water preparation.
Furthermore, the integrated circulation connection enables an even distribution of heat and optimizes the heating process, leading to increased energy efficiency.
Can be combined with photovoltaics
An additional special feature is the possibility of upgrading the storage system with a retrofittable [device/system]. 1 1/2" electric heating element to couple them. This allows the photovoltaic system to be used flexibly to generate additional hot water when needed.
The connection of the heating element to the buffer storage tank ensures a direct and rapid response to increasing hot water demand without compromising energy efficiency.
High-quality materials and corrosion protection
The drinking water storage tank impresses with its durable and corrosion-resistant construction. The high-quality enamel coating inside reliably protects the tank from corrosion damage and thus contributes to a long service life.
This protection is complemented by a generously sized magnesium anode, which acts as a sacrificial anode and provides further security for reliable operation.
Optimal thermal insulation
Thanks to a tightly bonded polyurethane foam insulation, the hot water storage tank is efficiently insulated. This reduces heat loss and supports the sustainable use of energy.
The technical design ensures that the stored heat is retained for a long period of time, thus keeping energy consumption to a minimum.
Technical specifications of the hot water storage tank
The storage volume is 100 liters, while the heat exchanger has a surface area of 1.2 m² and a volume of 5.27 liters. Connections for flow, return, and circulation are standard with 3/4" executed by AG.
Further technical details include: a maximum operating pressure of 6 bar, a maximum operating temperature of 95 °C in the storage tank and 100 °C in the heat exchanger, and low power loss of only 28 watts. The dimensions are 625 x 770 mm and the net weight is 64 kg.
Reliable addition: Elektromet heating element 2 kW
The integrated Elektromet heating element in a 2 kW version is the ideal addition for heating the hot water storage tank electrically. Thanks to high-quality stainless steel and a robust white plastic construction, the heating element is both durable and visually appealing.
Precise temperature control in the range of 5 to 75 °C, combined with a safety temperature limiter at 93 °C and a switch-on hysteresis of 7-10 °C, enables energy-saving and reliable operation. The connection is via a 1 1/2" The external thread and the included 1.5 meter long connection cable guarantee easy and quick installation.
With protection against splashing water (IPX4) and a maximum operating pressure of 10 bar, the heating element is suitable for both private households and commercial use, thus contributing to a safe and comfortable hot water experience.
