Condensing gas boiler Vaillant coTEC exclusive VC/VCW 1-7

A strong argument: Vaillant condensing gas boiler Green iQ

The ecoTEC exclusive meets the highest requirements for sustainable technologies and intelligent networking – and has been awarded the Vaillant Green iQ Label excellent.

The gas condensing boiler is produced in a resource-saving manner and consists of around 85% high-quality recyclable materials.

With the ecoTEC exclusive we are already taking a big step towards the future:

The device is already suitable for operation with up to 20% hydrogen* and up to 100% bio-natural gas. Manual adjustments are not required. In addition, it is H2 Ready in accordance with the GEG, because the ecoTEC exclusive VC can be converted to operate with 100% hydrogen* using a conversion kit.

This will be available from 2026. More information about hydrogen can be found here.

The self-adapting combustion system IoniDetect also offers many advantages:

  • Permanently records the combustion quality via the ionization current and optimizes it in case of deviations
  • Detects all types of natural gas and compensates for gas quality fluctuations
  • Optimal combustion guaranteed

Our ecoTEC exclusive is ideal for combining with heat pumps to create sustainable hybrid systems.

By using environmental heat, a significant proportion of the required energy is generated sustainably.

The Internet module sensoNET can be ordered free of charge for the ecoTEC exclusive using the voucher on the front of the device. In conjunction with the appropriate controller sensoDIRECT or sensoCOMFORT It allows your customers practical control via app – and you time-saving system maintenance remotely via myVAILLANT Pro.

So receive and install Your customers the Internet module:

1. Order via the QR code on the front of the device

3. myVAILLANT app download and get started

With the integrated, communication-capable high-efficiency pump, you can perform hydraulic balancing much faster and more accurately. The app "Grundfos GO Balance" guides you step by step through the entire process and automatically calculates the recommended flow rate for each radiator. After the hydraulic balancing, you will receive a PDF documentation in the app. You can provide this to your customers as proof of professional implementation of the measure – especially helpful for funding applications.

As a combination unit with integrated hot water preparation (VCW), the ecoTEC exclusive, with its advanced heat exchanger concept, achieves 8% higher efficiency than comparable standard units. It requires only 0.32 m² of wall space.The secondary heat exchanger with its 35 plates ensures particularly high hot water comfort.

  • Modulation: 1:10
  • Power sizes VC: 15, 20, 25, 30 kW
  • Power ratings VCW: 25 kW (in hot water mode even 36 kW)
