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

Product description

The Hot water storage tank 180 liters 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 a consistent and even hot water supply.

Efficient heat exchanger technology

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

Versatile energy sources

In addition to using solar thermal energy and conventional boilers, the storage tank can also be combined with a retrofittable 1 ½" electric heating element. This allows excess electricity from photovoltaic modules to be used profitably. The flexibility in 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 built-in magnesium anode acts as a sacrificial anode, extending the tank's lifespan. This ensures that the drinking water quality remains stable for years.

Comfort and capacity

With a usable volume of 180 liters, the ETWS storage tank offers ample reserves for showering, bathing, and everyday household tasks. The integrated circulation connection ensures that hot water is quickly available at all taps, eliminating long waiting times.

Easy integration and installation

The hot water storage tank can be combined with various systems, including solid fuel boilers, wood gasification boilers, pellet boilers, and combination 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 minimal heat loss and a consistently high water temperature. An additional connection for an electric heating element is already provided. The excellent price-performance ratio makes this storage tank an economical choice for any household.
