Electric water heater ZEUS SQUARE SLIM 50 L

ZEUS SQUARE SLIM 50 L is a modern electric storage water heater with a cubic CUBE design, engineered to provide stable hot water supply in an apartment, house, office, or vacation home. The 50-liter capacity is one of the most versatile options: it suits a small family and everyday scenarios (kitchen + washbasin, shower routines) while helping reduce electricity use thanks to intelligent functions. The unit is designed for vertical installation, and its compact dimensions along with reduced depth/thickness compared to cylindrical models make it easier to place in tight spaces—inside a niche, bathroom, technical area, or next to furniture—while maintaining a neat look. The white casing blends easily with bathroom and kitchen interiors.

Dry heating element and controllable heating power

The SQUARE SLIM series uses a dry heating element that does not come into direct contact with water. This technology increases the reliability of the heating assembly and reduces the impact of limescale on heating efficiency, which is especially important in regular use. The rated power is 2000 W, and to adapt to different conditions the unit offers power adjustment: 800 / 1200 / 2000 W. This approach is practical at home: you can select an energy-saving mode to maintain temperature or switch to maximum power when faster heating is required. For rapid warm-up to the operating temperature, the BOOST mode is available.

iECO: intelligent electricity savings

ZEUS SQUARE SLIM 50 L supports the iECO intelligent mode, which analyzes user habits (including shower scenarios) and manages heating so that hot water is prepared when needed. Fewer repeated heating cycles means lower energy consumption without reducing comfort. A timer function is also available, along with the ability to set hot water on a schedule—a convenient solution for predictable daily routines with clear morning and evening demand peaks.

Antibacterial protection and hygiene

To enhance sanitary safety, the unit provides 2 levels of antibacterial protection. 

• The first is the high-temperature “Anti-Legionella” (80°C) mode, intended for periodic water heating and bacterial prevention. 

• The second is an Ag+ antibacterial inlet, supporting more hygienic water intake. This is especially relevant for family use and for sites where water quality matters in storage heating systems.

Ti+ tank and service life

The inner tank is made of enameled steel with a Ti+ coating, resistant to corrosion and rust. The heating element is also enameled, improving resistance to scale and helping maintain stable heating performance. Reliability is supported by warranty coverage: 6 years on the tank and 2 years on the heating element—an important criterion when choosing a water heater for continuous operation.

Safety, connections, and key parameters

The unit operates on 220–240 V at 50/60 Hz, is rated for a nominal pressure of 0.75 MPa, and has electrical protection class I. Plumbing connection is standard 1/2" (bottom connection), which simplifies installation and ensures compatibility with common fittings. The multi-level protection system includes overheat protection, dry-heating protection, high-pressure protection, and a splash-protected enclosure rated IPX4. Noise level is around 15 dB, making it suitable for residential spaces and installation near resting areas.

ZEUS SQUARE SLIM 50 L is a rational choice for anyone looking for a 50-liter electric water heater in a compact cubic корпус, with a dry heating element, adjustable power, iECO intelligent mode, timer, and an extended safety system.
