Hot water tank 180 L with heating element 3 kW

180-liter hot water storage tank with 3 kW electric heating element

High-performance hot water storage tank for household and commercial use

The Hot water storage tank with 180 liters This high-capacity storage tank combines robust construction with maximum efficiency. It is ideally suited for private households and small businesses, guaranteeing a constant supply of domestic hot water. Thanks to its well-designed construction, the tank can be installed in a space-saving and flexible manner.

Efficient heat exchanger technology

The integrated heat exchanger converts the thermal energy from your solar thermal system or boiler into comfortable hot water. Its optimized surface minimizes heat loss and ensures the desired temperature is reached quickly. Sustained temperature stability provides comfort and reduces operating costs.

Versatile energy sources and retrofitting

In addition to solar thermal and boiler connections, the storage tank can be combined with a 3 kW electric heating element. This allows you to efficiently use excess electricity from photovoltaics or heat domestic hot water independently of external heat sources. This flexibility guarantees an uninterrupted supply in all weather conditions.

Modern heating element: 3 kW electric heating rod

The included electric heating element, made of high-quality stainless steel, offers a heating output of 3 kW and an adjustable temperature range of 5 °C to 75 °C. An integrated thermostat with switch-on hysteresis and a safety temperature limiter at 93 °C ensure reliable operation. The IPX4 protection rating allows for use even in damp environments.

Long-lasting corrosion protection

Inside, a robust enamel coating protects against corrosion and limescale deposits. An additional built-in magnesium anode acts as a sacrificial anode, preventing long-term material damage. This ensures consistently high water quality for years and minimizes maintenance.

Comfort and capacity

With a usable volume of 180 liters, the storage tank offers ample reserves for showering, bathing, and household chores simultaneously. The optional circulation connection ensures that hot water is available at all taps without any waiting time. This improves comfort and saves valuable time.

Easy integration and installation

The hot water storage tank can be combined with various heating systems, including solid fuel, wood gasification, pellet, and combination boilers. Retrofitting into existing solar thermal systems is also straightforward. All connections are accessible from the front, making installation and maintenance quick and easy.

The electric heating element is installed via a 1 ½" thread and has an installation length of 400 mm and an unheated length of 70 mm. The 1.5 m long connection cable with a Schuko plug allows for easy commissioning.
