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

Product description Hot water storage tank

The 120-liter hot water storage tank holds domestic hot water and ensures a central, reliable hot water supply. Thanks to a highly efficient heat exchanger, the water is optimally heated using thermal energy from a solar thermal system or a boiler.

An additional heating option is offered by the integrated 1 1/2" An electric heating element, which is particularly useful when combined with photovoltaic systems. This flexible addition transforms the hot water storage tank into a versatile component of your heating system.

Efficient hot water heating and protective functions

The internal heat exchanger and modern polyurethane foam insulation ensure energy-efficient and rapid water heating. The integrated circulation system also provides consistent hot water comfort for a demand of 100 to 180 liters.

The hot water storage tank boasts comprehensive corrosion protection. A high-quality enamel coating combined with a large magnesium anode ensures reliable operation over a long period and protection against internal corrosion damage.

Technical data of the hot water storage tank

With a volume of 120 liters and a heat exchanger surface area of ​​1.4 m², the storage tank is optimally sized. The connection options for flow, return, and circulation are 3/4", while the electric heating element also has a 1 1/2" A connection can be integrated.

The hot water storage tank is pressure and temperature resistant with a maximum operating pressure of 6 bar (at up to 95 °C in the tank) and at the same time has very low heat losses of only 32 watts – ideal conditions for efficient operation.

Powerful 1.5 kW heating element

The 1.5 kW electric heating element is the perfect accessory for additional, reliable heating power. Made of robust stainless steel and mounted in a durable plastic housing, it impresses with its longevity and safety.

The integrated thermostat allows you to precisely control the temperature range from 5 °C to 75 °C. A switch-on hysteresis of 7-10 °C ensures a constant temperature profile, preventing unnecessary switching cycles and minimizing wear.

Temperature control, frost protection and safety features

In addition to precise temperature control, the heating element also features an integrated frost protection mechanism that protects against damage during the cold season. Should the temperature reach 93 °C, the safety temperature limiter activates, ensuring overheat protection.

These well-designed safety features, combined with a compact design and flexible connection options via a 1 1/2" The connection makes the heating element an ideal component for supplementing hot water storage tanks in a wide variety of applications.

High-quality materials and easy installation

The heating element is manufactured with a robust heating coil made of Alloy 825, which withstands even high temperatures and demanding operating conditions. The durable plastic housing in an attractive white finish underscores the modern design and guarantees a longer service life.

The compact design, with an installation length of 300 mm and a 1.5-meter-long connection cable, allows for easy integration into existing systems. This means the electric heating element can be installed quickly and is ready for use in no time – both in private homes and commercial facilities.
