180-litre ETWS hot water tank: Efficient hot water preparation for your home

Product description

The Hot water tank 180 liters The ETWS is the ideal solution for central domestic hot water heating in private households and small businesses. With its generous capacity, it reliably covers hot water requirements of 100 to 180 liters. Its robust internal components ensure consistent and consistent hot water production.

Efficient heat exchanger technology

The integrated heat exchanger converts the thermal energy from your solar thermal system or boiler into pleasant domestic hot water. Thanks to its high efficiency, the temperature is reached quickly and maintained for a long time. It ensures low heat loss, thus saving energy and costs.

Versatile energy sources

In addition to the use of solar thermal energy and conventional boilers, the storage tank can also be combined with a retrofittable 1 1/2" electric heating element. This allows excess electricity from photovoltaic modules to be profitably utilized. The flexibility of the energy connection ensures an uninterrupted supply of hot water.

Long-lasting corrosion protection

Inside the tank, a high-quality enamel coating protects against corrosion and limescale deposits. An additional magnesium anode acts as a sacrificial anode and extends the lifespan of the tank. This ensures that the quality of the drinking water remains stable for years.

Comfort and capacity

With a usable volume of 180 liters, the ETWS storage tank offers sufficient reserves for showering, bathing, and daily household tasks. The installed circulation connection ensures quick hot water availability at all taps, making long waiting times a thing of the past.

Easy integration and installation

The hot water tank can be combined with various systems, including solid fuel boilers, wood gasification boilers, pellet boilers, and combi boilers. Integration into existing solar thermal systems is also straightforward. Installation is space-saving and flexible, ensuring optimal access to all connections.

Technical highlights

The polyurethane foam (PUR) insulation ensures low heat loss and a consistently high water temperature. An additional connection for an electric heating element is already provided. The solid price-performance ratio makes the storage tank an economical choice for every household.
