At Vaillant we are working towards low carbon solutions today. As part of the HyDeploy project, Vaillant boilers have been tested with up to 20% hydrogen blended with Natural Gas, and we are currently undergoing many tests to each of our boilers to validate their compatibility with up to 20% hydrogen.
