ATAG i36C Combi Boiler Pros and Cons
Moving beyond raw performance numbers, let's weigh what makes the ATAG i36C stand out – and where it might fall short.
You'll appreciate the impressive 94% efficiency rating and whisper-quiet operation that won't wake the kids during those early morning showers.
The standout advantages include:
- A generous 10-year warranty that's extendable to 14 years
- Compact design that fits neatly in your kitchen cupboard
- Built-in weather compensation to help reduce those heating bills
However, you should know it's not all sunshine and rainbows.
The i36C comes with a higher price tag than many competitors, and you might find it harder to source replacement parts.
Plus, if you're living in a smaller property, this boiler could be more powerful than you need.
How Does The ATAG i36C Combi Boiler Compare To Similar Models From Other Manufacturers?
Stacking up against industry heavyweights like Worcester Bosch and Vaillant, the ATAG i36C holds its own with some impressive specs.
While its heating output is slightly lower at 31.2 kW compared to the competition's 35 kW, it matches their 94% efficiency rating.
You'll find the i36C's hot water flow rate of 14.9 l/min sits comfortably between its rivals, though the Viessmann Vitodens 200-W takes the lead at 16.4 l/min.
What might catch your eye is the i36C's compact dimensions – it's one of the smaller units in its class.
The standout feature? ATAG offers the longest warranty at 14 years, beating Worcester's 12 years and Vaillant's 10 years.
Plus, that lifetime guarantee on the iCon heat exchanger isn't something you'll find elsewhere.

How Much Does A ATAG i36C Combi Boiler Cost?
The price tag on an ATAG i36C Combi boiler might make you do a double-take at first glance.
You're looking at £1,425 to £2,300 for just the boiler itself, and that's before we talk about installation.

- Supply-only cost: £1,425-£2,300
