A brief, riveting and oddly in-depth testimonial to the Baxi Duo-tec combi boiler. They've sold a fair few, but are they worth a punt?
Baxi Duo-Tec Combi Boiler Brand History
Founded in 1866 and with their manufacturing centre based in Preston, Lancashire, BAXI is a British made boiler brand with a solid offering of combi, regular and system boilers engineered to last the test of time.
Today Baxi are still trying to improve the lives of many. Through instant hot water and lightning-fast heating.
In recent years, their Baxi Duo-Tec boiler has been an incredibly popular choice across the nation, so how does it compare and perform against other leading brands?

Baxi Duo Tec 28 Key features:
Here are some of the Duo-tec features, as described by Baxi.
7 Year Warranty*
Instant hot water (as per all working combi boilers)
Easy to use controls (thanks)
Meets the minimum energy efficiency rating required for Boiler Plus compliance
Energy Saving Trust endorsed
A fine set of perks, but let's delve a little deeper, beyond the lovable modesty of Baxi.
A 7-year warranty*. Firstly, we'll address that potentially worrying asterisk. Don't worry, Baxi hasn't given you a comprehensive guide on how to treat your boiler like it's some sort of mains gas-powered Gremlin.
The asterisk is essentially just confirming that they won't honour the guarantee if your local car mechanic thought he'd 'just give it a go' when it came to the boiler installation and that you'll need to keep up with the annual servicing (a wise move anyway).
Stick to the simple rules, have it installed by a Gas Safe engineer and you're covered for a whopping seven years - there are manufacturers out there offering warranties closer to seven minutes, so don't take a 7-year one for granted - however, other budget boilers and certainly top brands do now tend to offer 10-years as standard.
Instant hot water. Baxi isn't happy with fast. Fast is pathetic. Baxi is giving you instant hot water because who on earth has the time to wait 4 seconds for hot water? You've got a life to live, and mouths to feed.
Easy to use controls. It is upsetting but there are manufacturers of boilers out there who have designed boiler controls that require you to think whilst engaging with them. Baxi won't stand for this nonsense. Baxi wants you to be able to pop your heating on whilst you're utterly inebriated, or 6 years old.
Meets the minimum energy efficiency rating required for Boiler Plus compliance. All modern boilers are now required to meet a minimum efficiency rating, so there is little difference between all modern combi boiler models. The Baxi Duo Tec range is no different. It’s 89% efficient which is superb, but it’s slightly lower than the Worcester Bosch range and other peers.
Energy Saving Trust endorsed. Who are the Energy Saving Trust you're asking? They are a charity that takes energy efficiency more seriously than just about anyone, so being endorsed by them is pretty impressive.

Baxi Duo Tec Reviews
As of 2024, Baxi UK hold almost 60,000 reviews on the Trust Pilot review platform.
They hold a score of 4.6 out of 5 stars. It’s fair to say that’s a great score across any industry, but particularly for a boiler manufacturer.
When someones boiler breaks, their patience is shorter than Ronnie Corbett. This means they will instantly take to the internet to leave scathing and regularly unjustified reviews.
Baxi aren't just making these figures up. When Baxi say they've got 489 reviews, you can read every single one of those 489 reviews. We took a look at a few of them to gain some insight.
We'll take a closer look at just a couple of reviews below.
This is Greg. Greg spells his name in capital letters. Greg is a landlord. Greg gave Baxi 10/10.
You might think Greg mentioning his exploits in property lettings is utterly irrelevant but as a landlord, he's probably had more boiler replacements than the average Joe. Greg needs quality and value. Greg got a Baxi. It's safe to assume he bought himself one too.
Greg has made a typo on the word 'to'. Whilst trying to tell us that his Baxi Duo-tec 24 is easy to use, Greg - who has so much extra time because of the instant hot water he's getting from the Baxi Duo-tec - has had ample time to pop an extra character in what is usually, a two-letter word. For the sake of Greg, we must stress the 'h' is silent.
Negative reviews - 'Reviewer left no comment'. This is Greg, remember? Greg who shouts his name in capital letters, Greg the landlord - an occupation requiring almost mandatory complaining - couldn't even comprehend entering text into that negative review box.
Below is Linda. She also has a fondness for the caps lock, a developing theme that we'll perhaps delve into in a future article. Linda has kept things even more simple but it in no way defers the excellence of Baxi.
Positive points - Linda says it's easy to use, with a 7-year guarantee. Linda is so flabbergasted by the Baxi Duo-tec, so dumbfounded that she's quite simply copied and pasted Baxi's own listed product points into the review platform.
Negative points - Linda says there are 'no bad pints'. We couldn't agree more with Linda on this point and it is perhaps more philosophical than we can begin to fathom but we'd urge you to revert to the 'easy to use controls' point from the earlier Key Features section. We suspect Linda is loving the ease of use with which a Baxi can be controlled.
Further insight into the good people of Baxi
Here's another snippet from the Baxi website. These welcoming contact details and useful FAQs aren't buried deep in the abyss of a one-thousand-page website.
They're thrust - albeit delicately - into your searching gaze, the second you land on their website. Baxi knows that sometimes, things go wrong.
