ECOCONDENS NEX gas condensing boilers are innovative devices of the highest technical level in the category of gas wall-mounted boilers intended for heating and preparing domestic hot water. The high efficiency of the devices as well as the wide range of modulation make these devices very economical and environmentally friendly. Additionally, a guarantee of high comfort of use is the LIN interface, which allows you to connect the Termet Comfort System to remote control via the Internet. The distinguishing feature of the ECOCONDENS NEX series boilers is their extremely smooth and quiet operation.
- energy class: A
- modern stainless steel heat exchanger characterized by high resistance to corrosion and scaling
- the latest generation CERAMAT burner made of ceramic fiber, distinguished by an extremely wide range of modulation, allowing for optimization of the combustion process and gas savings
- additional boiler soundproofing system based on modern sound-absorbing materials
- very quiet operation of the boiler - only 37 dB (applies to 24, 28 kW boilers)
- highly efficient circulation pump
- electronically controlled modulated fan
- highest NOx class (class 6)
- complete security system
- possibility of working with multi-zone modules for heating systems
- possibility of cooperation with air/water heat pumps
- cooperation with domestic hot water tanks through the built-in three-way valve
