The Baxi Duo-tec Combi GA Boiler

www.baxi.co.uk

When you buy a new boiler, we understand
that it is a considerable investment. That’s
why we want to make sure you have a
reliable boiler that will generate efficient
heat and hot water for years to come.

So ask your installer to fit you a Baxi boiler.

Warmth, efficiency and
total peace of mind

Why choose Baxi?

There’s no feeling quite like coming home on a cold day knowing it’s
going to be warm and cosy indoors. Or turning on the hot tap to be
rewarded with an endless supply of hot water.

You rely on your boiler so much that sometimes you’ll only notice it
when you need to repair or replace it.

If you’re used to living with a boiler that’s over 10 years old, you’ll be
amazed at the savings you can make by replacing it with a new one.
The Baxi boiler efficiency calculator will help you to discover how
much could potentially be saved on fuel bills by fitting a new A rated
boiler in comparison to an existing boiler.

air mix it is burning to ensure it is running as efficiently as possible.

and environmentally sound decision which is Energy Saving Trust
recommended.

as you turn on the hot tap. This means
they’re economical to run, as hot water is

or a hot water storage cylinder… perfect if
space is at a premium.
