    Vaillant is a well-known brand in the heating and boiler industry, and they are generally recognized for producing energy-efficient boilers. The energy efficiency of Vaillant boilers can vary depending on the specific model and its features. Vaillant boilers often come with high-efficiency condensing technology, which is designed to extract more heat from the combustion process, making them more energy-efficient compared to older non-condensing models.
