The Nefit TrendLine II is the first of a new generation of high-quality HR boilers. Reliable comfort, compact design, and "future-proof." Ready for different gases and for combination with a hybrid heat pump.
With the TrendLine boiler, you're bringing the future into your home in every way. The smartest software automatically detects patterns in your hot water usage. This ensures that the boiler provides the optimal balance between comfort and energy savings. Additionally, the TrendLine boiler is ready for potential changes in gas composition, and it is possible to mix in biogas.
The smart, self-learning software automatically ensures optimal comfort and maximum energy savings for the boiler. Remote control via smartphone? That’s possible with the well-known Nefit Easy or EasyControl from Bosch. The latter even allows you to control the comfort in each room individually.
The TrendLine NxT is factory-made to connect to all standard flue gas and air supply systems, both parallel and concentric.
