Wondering if Ideal boilers are really the quietest on the market?

If you’re looking for a quiet boiler, you may have had an experience with a noisy boiler in the past. Or maybe you’re thinking of fitting your new boiler in a bedroom cupboard or attic, and need it to be very discreet!

Either way, an Ideal boiler is a good choice – because of one very compelling reason; the Quiet Mark.

As an engineer with over 20 years’ experience in the Edinburgh area, I’m going to explain to you why Ideal boilers are the quietest on the market. And what that means for you!

Why are Ideal boilers the quietest?

Let’s start by looking at the example of market leader Worcester Bosch. They went down the road of getting the accolade of Which ‘Best Buy’. It’s strange because the likes of Ideal and Baxi are NOT going down that road. Ideal are offering long guarantees and a good, reliable product, but they’re doing it in a different way.

So, getting the Quiet Mark stamp of approval is their unique selling point. A lot of people don’t like the idea of a loud boiler. Combine the Quiet Mark with the new Logic Max and Vogue Max ranges with up to 12-year guarantees? It’s not wonder Ideal are now the second-biggest selling boiler brand in the UK. Second only to Worcester Bosch!

If you ask me personally on listening to them, I’d say the Logic+ (or Logic Max) is quieter than Worcester Bosch’s Greenstar i range of combis. However, comparing it to the CDi range? There’s really not much in it; at least from a human perspective.

That’s not discounting all of the tech they use to pick up noise levels – but when you’re actually standing there, that’s the real difference (in my opinion). 

What’s the advantage of this?

Well, the main advantage of a super quiet boiler is that you can install them pretty much anywhere. They won’t wake you up or produce an annoying/distracting noise when you’re at home trying to sleep or relax.

You could happily install a boiler with the Quiet Mark in a bedroom, or in your attic, and it won’t make much of a difference.  Say if someone in your household gets up at 5am and takes a shower – your boiler will be running, but it won’t disturb you (hopefully).

I’ve advised a lot of clients on this. One couple had a three-bedroom, semi-detached house with a small kitchen. They wanted to put their boiler in the attic to save space. However, the attic is a big open space – usually above bedrooms – which can cause an echo.

I pointed out about the echo in the attic, and once they did their research and came back to me, they told me it had to be a Vaillant or an Ideal. This is because both have the Quiet Mark. This was a great outcome as I never want customers coming back to me in six months’ time complaining about noise levels.

Advice from an experienced engineer

If you’re looking for a super quiet boiler (like Ideal), always look for the Quiet Mark. You won’t find this on most Italian brands of boilers. However, don’t be afraid to ask your engineer about the quietness of certain models. Ask them how many they’ve fitted, and see what they advise.

I’ve had customers who tell me a quiet boiler is really important to them. I find this is especially true if they’ve previously owned an old Italian boiler, as they’re often particularly noisy when they fire up and are running.

After that experience, a lot of people don’t want a boiler that makes the same noise. I find they’d rather pay more for a quiet boiler – much in the same way that a lot of people are happy to pay more for a longer guarantee. It’s just makes sense.


I hope you’ve enjoyed reading. Ideal is currently one of the quietest boilers on the market, along with Vaillant. This means that it’s easy to install your Ideal boiler in an attic or bedroom, and you won’t be disturbed in the middle of the night.
