History of BAXI
A rm favourite with homeowners and installers alike, Baxi
is one of Europe’s largest and longest-established boiler
manufacturers. We have over 150 years of engineering
experience – so we know a thing or two about how to do
it right. We’re very proud not only of our long heritage
of quality and innovation, but also that we continue to
manufacture here in the UK.
We strive for perfection and always listen to customer
feedback, resulting in boilers like the Baxi Duo-tec Combi
GA that set new standards in efciency and reliability.
As for reliability, you can take it for granted with Baxi
boilers. They’re designed to operate at maximum efciency
throughout their lifetime, and tested rigorously for your
peace of mind.
All Baxi boilers are Energy Saving Trust recommended
products to give your customer added peace of mind.
The brand that stands for quality
and innovation
Made in the UK

Innovative THINK technology
Innovative THINK technology –
the heart of every Baxi GA boiler
Our world-beating technical innovation is focused on
delivering years of reliable and economical service and the
maximum environmental benet.
Take our pioneering THINK technology, for example, found
at the heart of every boiler in the Baxi GA range. THINK
is designed to deliver smooth, reliable and cost effective
performance by continuously monitoring and adjusting
the boiler’s output to maximise burner efciency. Gas
consumption is lower, component wear and tear reduced
and reliability increased.
A wide modulation range means that Baxi GA boilers
maintain even temperatures without repeatedly
switching on and off. Once the home reaches the desired
temperature, the boiler simply adapts its output to
maintain that temperature more effectively. Less gas is
used to re-ignite the boiler, reducing both fuel bills and
carbon emissions. The gures speak for themselves:
† Baxi laboratory testing & analysis has shown these reductions when measured
against a standard Baxi high efciency boiler.
* Based on average fuel consumption of a UK household as calculated in the British
Gas Home Energy Report 2011, when measuring a Baxi Duo-tec 28 GA compared
to a Baxi Duo-tec 28 HE A boiler
8.7% more
Efficient†
£71 saving

A Baxi GA boiler
is 8.7% more

An additional saving
of £71 per year*
can be achieved
by having a Baxi
GA boiler over a
standard Baxi high

A boiler that
reduces CO2
