  • ecoTEC plus with IoniDetect as standard and in new design

  • Vaillant ecoTEC plus recognises the gas type and automatically compensates for fluctuations in gas quality

  • Vaillant ecoTEC plus also suitable for liquid gas

Vaillant has completely upgraded the ecoTEC plus gas-fired condensing boiler: The new ecoTEC plus is equipped with IoniDetect self-adapting combustion control as standard. So far, IoniDetect has only been used in ecoTEC exclusive. IoniDetect makes Vaillant gas-fired boilers future-proof and ensures that they work particularly efficiently. Each boiler automatically adjusts to different gas types and qualities and can also run on liquid gas, thus ensuring clean, safe and efficient combustion at all times. The boilers, which are even more economical now, are easy on the environment and on the wallet.

“We will need to expect fluctuating gas types and qualities in the future, and so we are continually improving our gas-fired condensing systems and increasing their flexibility,” says Sebastian Albert, Head of Product and Service Management at Vaillant Germany. “Our modern intelligent technology puts them in an ideal position for different gas types and qualities.”

New design and Internet connection

The new ecoTEC plus has been designed from scratch and adjusted to suit its storage solutions. The ecoTEC plus includes the option of adding an Internet interface, the sensoNET Internet module, which can easily be connected underneath the boiler in a plug-and-play installation, providing it with Internet connectivity and allowing remote servicing. This saves time and money, both for the installer and for the customer. The owner of the heating system can control the appliance via an intuitive smartphone application called sensoAPP. With the purchase of an ecoTEC plus Vaillant customers will be given the sensoNET Internet module for free during the campaign period from 1 April to 30 June 2021.

ecoTEC exclusive now also suitable for liquid gas

The Vaillant ecoTEC exclusive gas-fired condensing boiler has undergone further technical development and now also runs on liquid gas – at the same purchase price. This will open up new market opportunities for installers. As a hybrid system in combination with solar thermal energy, the ecoTEC exclusive gas-fired condensing boiler has an energy efficiency rating of A+. It also has been awarded the Vaillant Green iQ label for particularly sustainable and highly efficient Vaillant heating technology combined with intelligent and intuitive controls.

Thanks to intelligent combustion control, the new ecoTEC plus and ecoTEC exclusive are fail-safe and low-maintenance. Also, the user-friendly device and control concept provides support for installers, ensuring that installation and set-up are both simple and fast.

One-stop shopping

For hot-water production, the Vaillant range includes two wall-hung hot-water storages: the uniSTOR and actoSTOR, specially tailored to suit Vaillant gas-fired condensing boilers, both technically and visually. Alternatively, there are combination appliances, either with integrated hot-water generation or with integrated hot-water storage.
