    We take a quick look at a couple of Baxi and Vaillant combi boilers to help you decide.

    Both are made in the United Kingdom by companies with over a century of experience.

    We examine one best combination boiler (combi) from each company. These are tankless water heating systems, which are now the most common types of boilers.

    They also do other types of boilers such as system and regular boilers, but they are becoming increasingly rare. You will no longer be considering turning off your boiler at night.

    To be fair, we will also consider similar output in the same price range from both. Please keep in mind that this does not include installation by a Gas Safe registered engineer!
