We've made our best-selling boiler even better - using the latest technology to provide a reliable heating solution for the future. Its optimum price/performance ratio makes it a really good choice. Proven quality guarantees a long service life, while innovative features increase its efficiency. All this contributes to a significant reduction in your costs.
Be prepared for a change in gas composition
Thanks to the new IoniDetect combustion control technology, the boiler itself detects fluctuations in gas composition, can adapt and always works most efficiently. This feature will be most appreciated in the future when using more environmentally friendly gas mixtures.
Innovate your system with renewables
The new ecoTEC plus provides a sustainable heating solution. Especially in conjunction with the sensoCOMFORT system controller, you can optimally adjust your
heating system - and thus save both energy and heating costs. Thanks to the new installation assistant, you can ensure that your boiler always operates at maximum efficiency while providing you with maximum comfort. For greater sustainability, you have the option of adding various flexible options to extend your system with
renewable energy sources: solar heating, heat pumps or ventilation systems with heat recovery. Their common
eBUS communication language allows easy installation and control of the entire system.
There are only a few steps to control your new heating system via an online app from anywhere. You need to add the sensoNET
internet module to your boiler, which you can connect seamlessly with your boiler using the plug-and-play system (i.e. it works as soon as it is plugged in) and download our free app. You can then control it, for example, when you go on holiday. This option is not just for your convenience. Because your heating only runs at full blast when you actually need it, you save energy, your costs and the environment.
Convenient heating monitoring
Do you like to be in control of your energy consumption? Especially in combination with the sensoCOMFORT system controller, you can comprehensively control your boiler and have detailed consumption data at your disposal. Thanks to the new user interface with touch elements, monitoring the boiler operation becomes more convenient than ever. Enjoy our modern design and user menu for intuitive and trouble-free operation.
