100-litre drinking water storage tank with 2 kW heating element – ​​reliable hot water heating

Product overview

The 100-liter hot water tank ETWS is a modern solution for centralized hot water heating in both residential and commercial applications. It offers optimal hot water comfort for demand from 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 production.

Efficient hot water heating

Inside the storage tank is a powerful heat exchanger that effectively transfers the thermal energy from solar thermal systems or boilers to the domestic water. This ensures fast and reliable hot water production.

The integrated circulation connection also enables even heat distribution and optimizes the heating process, leading to increased energy efficiency.

Combinable use with photovoltaics

An additional special feature is the possibility of retrofitting the storage with a 1 1/2" Electric heating element This allows for flexible use of the photovoltaic system to generate additional hot water when needed.

The connection of the heating element to the buffer 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 on the interior reliably protects the storage tank from corrosion damage, thus contributing to a long service life.

This protection is complemented by a generously dimensioned 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 tank is efficiently insulated. This reduces heat loss and supports the sustainable use of the energy used.

The technical design ensures that the stored heat is retained over a long period of time, thus keeping energy consumption to a minimum.

Technical key data of the hot water 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" AG carried out.

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 consumption 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 2 kW Elektromet integrated heating element is the ideal addition for electrically heating your hot water tank. Thanks to its high-quality stainless steel and 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 with 1 1/2" External thread and the included 1.5 meter long connection cable guarantee easy and quick installation.

With protection against splash 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.
