All the boilers I fit have a 5 year warranty.
The difference is, I do not rely on internet forums to tell me what is good, otherwise we would have been fitting Kestons for the last 5 yrs.
You must be reading different forums to me then. The Keston Celsius was a dog and many here say so. Keston quality dropped off in the past 5 years, although the new boiler, the Qudos, is gaining ground.
We go on build quality, ease of maintenance and percentage of failures. The Remeha is not outstanding but good in all these areas. By far and away the most reliable boiler we have fitted in the last 36 months has 'Vaillant' written on it.
Vaillant are reliable enough. But they have made some dogs. They are expensive and poorly specced to other makes, to the point I would avoid most of their models them until they get the specs up and prices right. And that goes for Worcester-Bosch too. They are over priced for what they are.
When looking at quality makes around it is difficult to home in on Vaillant as they just don't make it.
