I'd like to start with something a little off the wall, the pronunciation. There seems to be a pandemic among customers, installers, and even Vaillant boiler staff! The common mispronunciation of the Vaillant boiler brand is 'Val-iant - boilers'. We often correct people on the phone but most just believe we have it wrong which can be slightly awkward.
Moving on swiftly, Vaillant boilers are a German brand we rate very highly, certainly against competitors such as Worcester bosch. Their build quality is second to none and their compensation controls are easier to fit, particularly on retrofits than any other brand. More on compensation control.
For the purpose of this article we are going to assume you know the difference between a regular, system and combination (combi) Vaillant boilers, and talk more about the range of Vaillant boilers available.
