While both Vaillant and Potterton have left their mark on the heating industry, their paths couldn't be more different.

You'll find Vaillant sitting comfortably at the top of the heating industry today, operating in over 60 countries with a whopping €3.7 billion in annual turnover. They're basically the Mercedes-Benz of boilers!
Potterton, on the other hand, has taken a different route.
Now part of Baxi Heating, they've positioned themselves as the practical choice for budget-conscious homeowners.
While they may not be the independent manufacturer they once were, they're leveraging Baxi's expertise to deliver reliable, cost-effective heating solutions that won't break the bank.
