Information
The Vaillant ecoFIT pure 830 boiler is lightweight and compact but doesn’t mean you have to compromise on comfort. The ecoFIT pure’s powerful aluminium heat exchanger offers outstanding performance and low energy consumption for any home.
It’s smart, too. When you don’t need as much heat, it will reduce itself to just 20% of its maximum output – meaning greater energy efficiency and lower bills for you. And because it works with vSMART™, you can control your low-cost, climate-friendly heating via the internet.
Vaillant is working towards low carbon solutions today. As part of the ongoing trials, Vaillant boilers have been tested with up to 20% hydrogen blended with Natural Gas.
Vaillant is currently testing each of its boilers to validate compatibility with up to 20% hydrogen.
