Hot water tank 100 liters with 1.5 kW heating element

100-liter hot water storage tank with 1.5 kW heating element

Product overview Hot water storage tanks

The ETWS 100-liter hot water storage tank offers a central and reliable solution for hot water heating. It is ideally suited to meet domestic hot water demands via a highly efficient heat exchanger and can be used in both residential and commercial applications.

Thanks to the integrated heat exchanger, energy from solar thermal systems, boilers, or alternative systems is optimally used for water heating. This flexibility enables demand-based and energy-efficient hot water preparation.

Efficient hot water preparation

The internal heat exchanger ensures efficient heat transfer to the domestic hot water. This allows even excess energy from alternative energy sources such as photovoltaic systems to be used effectively – further enhanced by the option of connecting a retrofittable electric heating element.

The insulating polyurethane foam, firmly foamed, reduces heat loss and thus contributes to a high level of hot water comfort, which is reliably met even with increased demand of 100 to 180 liters.

Protection and durability

The drinking water storage tank is protected against corrosion by a high-quality enamel coating on the inside. Additionally, a generously sized magnesium anode acts as a sacrificial anode, providing further protection and thus extending the service life of the unit.

The integrated circulation connection and various connection options ensure easy integration into the existing system and optimize the operation of the entire hot water preparation process.

Technical data for hot water storage tanks

Volume: 100 liters; Heat exchanger surface area: 1.2 m²; Heat exchanger capacity: 5.27 liters. The connections for flow, return, and circulation are each 3/4" AG, supplemented by a 1 1/4" Internal thread connection for the magnesium anode and a 1 1/2" Internal thread connection for the electric heating element.

The storage tank operates at a maximum temperature of 95 °C and an operating pressure of 6 bar, while the heat exchanger can withstand temperatures up to 100 °C. Its low power loss of 28 watts and compact dimensions (625 x 770 mm) make this hot water storage tank a space-saving and efficient solution.

High-performance heating element

The 1.5 kW electric heating element is a robust and versatile accessory that optimally supports the hot water storage tank. Made of high-quality stainless steel and equipped with a sturdy thermostat housing, it guarantees fast and reliable water heating.

The heating element impresses with its compact design and its easy integration into the existing system, as it can be seamlessly connected via a 1 ½" connection.

Precise temperature control and safety

With an integrated thermostat covering a temperature range of 5°C to 75°C, the heating element allows for precise control of the water temperature. The 7-10°C switch-on hysteresis ensures stable operation and avoids frequent switching cycles, thus reducing wear.

An integrated frost protection mechanism ensures operation in cold environments, while a safety temperature limiter at 93°C protects against overheating and provides additional safety.

High-quality materials and easy installation

The heating coil, made of Alloy 825, is characterized by excellent corrosion resistance. The durable, white plastic housing not only underscores the modern design but also the robustness of the device. The IPX4 protection rating also ensures reliable splash protection.

Thanks to an installation length of 300 mm (with an unheated length of 70 mm) and a 1.5 meter long connection cable with Schuko plug, installation is quick and easy – so the heating element is ready for use in no time.

Technical data heating element

Heating capacity: 1.5 kW; Temperature range: 5-75°C; Switch-on hysteresis: 7-10°C. The installation length is 300 mm, with 70 mm remaining unheated. The safety temperature limiter activates at 93°C, and the heating element is designed for a maximum operating pressure of 10 bar.

With a 1 ½" male thread connection and IPX4 protection rating, combined with the durable Alloy 825 material, the heating element combines modern technology and safety at a high level.

Versatile applications

The hot water storage tank, in combination with the powerful electric heating element, is suitable for a wide range of applications. It can be integrated into both residential and commercial buildings, and its easy integration with solar thermal systems, pellet boilers, or wood gasification boilers opens up further possibilities.

This flexibility makes the system a sustainable investment that meets the high demands of modern hot water concepts.

Conclusion

The combination of an efficient 100-liter hot water storage tank and a 1.5 kW electric heating element offers a powerful and safe solution for hot water preparation. With well-designed safety features, durable materials, and a user-friendly design, this system is impressive in every respect.

Whether as a complement to renewable energies or as reliable support in conventional heating systems – this product represents a modern and future-proof choice for anyone who values ​​the highest efficiency and quality.
