How to buy a boiler?

It’s fair to say that some of the terminology around boilers and central heating systems can be complex and sometimes confusing, which is why we always advise contacting a qualified heating engineer who can advise on the best heating system for you and your requirements.

But finding a Vaillant installer couldn’t be simpler, and like us they’ll be with every step of the way.

Once you have contacted your chosen installer(s), they will arrange an appointment to visit your home, understand your requirements and give you a quote for the installation, product, controls and any power flushing or chemical treatments.

By choosing a Vaillant Advance Partner, you’re choosing our network of fully trained, independent installers who can offer you exclusive extended guarantees, as well as a free no obligation quote to ensure your Vaillant boiler is the perfect fit for you and your home.
