The ecoTEC plus 620 System Boiler is a smart, high-efficiency heating solution that combines cutting-edge technology, innovation, and reliability. Hand-built in Vaillant's award-winning Derbyshire manufacturing plant, it offers intelligent performance, enhanced connectivity, and precision control for modern homes.

Why Choose a System Boiler?

System boilers deliver heating and hot water efficiently while requiring a hot water storage cylinder, making them ideal for larger homes with higher hot water demands. They don’t require a separate cold water tank, offering a compact yet powerful heating solution.

Features:

  • Smart home ready – Works seamlessly with myVAILLANT connect for app control, smart home integration, and remote appliance support.
  • Refined internal layout – Enhanced design allows for easy access to all components, making installation and servicing effortless.
  • Familiar footprint & external layout – Retains the same case dimensions, flue position, and pipe connections for a simple like-for-like swap.
  • New intuitive semi-touch interface – Provides an effortless setup experience with a guided commissioning wizard and easy-to-follow navigation.
  • Automatic LPG conversion – Converts to LPG in minutes, with no additional parts required.
  • New IoniDETECT technology – Intelligent gas combustion monitoring for a wider modulation range of 1:8, ensuring greater efficiency and lower energy consumption.
  • Sharpened intelligence with LINbus technology – Enhances flow rate and pressure monitoring via the internal pump, leading to improved system performance.
