Condensing gas boiler EcoCondens NEX 28/35 dual-purpose wall-mounted WKD 5611 00 00 00/PL

Modern comfort and savings with EcoCondens NEX 28/35

The EcoCondens NEX 28/35 condensing gas boiler is an advanced heating solution designed for both heating homes and apartments, as well as for efficient domestic hot water preparation. The device is characterized by high energy efficiency, which translates into lower gas bills and a reduced environmental impact. Thanks to the wide range of modulation, the boiler optimizes the combustion process, adapting to the current thermal needs of the building.

A key element of the construction is a modern heat exchanger made of stainless steel, which ensures exceptional resistance to corrosion and scale formation – a guarantee of long-lasting and trouble-free operation. The CERAMAT burner made of ceramic fiber further increases combustion efficiency, and the noise reduction system minimizes noise levels during operation.

• High efficiency: Energy class A ensures minimal energy losses and reduces operating costs.
• Durability: The stainless steel heat exchanger resistant to corrosion and scale is a guarantee of long life.
• Quiet operation: The advanced noise reduction system makes the boiler operate extremely discreetly.
• Power modulation: The wide modulation range allows for precise adjustment of power to demand, which translates into savings.
• Compatibility: The ability to cooperate with multi-zone modules and air/water heat pumps expands the possibilities of using the device in various heating systems.
• Remote control: The LIN interface allows connection to the Termet Comfort System and remote control of the boiler via the Internet – full control over the temperature in your home, wherever you are.

Design and application

EcoCondens NEX 28/35 is a dual-function, wall-mounted boiler, which means it can be mounted on the wall, saving valuable space in the boiler room. The device is adapted to cooperate with traditional heating installations as well as with low-temperature systems, such as underfloor heating. Thanks to the high NOx emission class (class 6), the boiler meets stringent environmental standards. A high-efficiency circulating pump and an electronically controlled modulated fan further increase the efficiency of the device. The boiler has a complete safety system ensuring safe operation.

Operating parameters and specifications

The EcoCondens NEX 28/35 boiler is characterized by a heating power in the range of 3.5 to 28.2 kW (at 80/60°C) and from 3.9 to 31.1 kW (at 50/30°C). The nominal power for DHW is from 3.5 to 35.2 kW. The capacity of the expansion vessel is 8 liters and the dimensions of the device are 767 x 450 x 350 mm with a weight of approximately 55 kg. The sound power level is 47.8 dB, which guarantees quiet operation of the device in a living room or boiler room. The boiler has connections for heating water and gas G ¾ inch and domestic hot water G ½ inch.
