You'll get plenty of heating power with its 23.2kW output, enough to handle up to 15 radiators in your home.
The 30.3kW hot water output delivers a strong 11.5 litres per minute flow rate – perfect for those morning showers.
This A-rated boiler achieves 94% energy efficiency, helping keep those bills in check.
You can make it even smarter by adding the ATAG ONEZone controller, bumping the rating up to A+.

ATAG i28C Combi Boiler Performance and Efficiency
When it comes to performance and efficiency, you'll find the ATAG i28C combi boiler punches well above its weight class. With a seasonal space heating efficiency of 94% and an ErP A rating, you're looking at potential savings on your annual gas bills.
| Feature | Rating | Benefit |
|---|---|---|
| Heating Output | 23.2 kW | Powers up to 15 radiators |
| Hot Water Output | 30.3 kW | Strong shower pressure |
| Flow Rate | 11.5 l/min | Quick bath filling |
The boiler's iCon heat exchanger comes with a lifetime replacement guarantee, while its bottom-up modulation keeps operation whisper-quiet. You'll particularly appreciate the built-in weather compensator that adjusts performance based on outside temperature – it's like having a smart thermostat built right in!
ATAG i28C Combi Boiler Pros and Cons
Building on those impressive performance specs, let's evaluate what makes the ATAG i28C shine and where it might fall short for your home.
On the plus side, you'll love that it fits neatly into a standard kitchen cupboard and comes with a generous 10-year warranty (extendable to 14 years). The 94% efficiency rating and ErP A rating mean you'll save on energy bills, while the iCon heat exchanger's lifetime guarantee offers great peace of mind.
However, it's not all perfect. The 11.5 l/min flow rate might leave you wanting more if you've got a busy household running multiple showers.
You'll also need to take into account the higher upfront cost and potentially limited installer options since ATAG isn't as widely known in the UK as some other brands.
How Does The ATAG i28C Combi Boiler Compare To Similar Models From Other Manufacturers?
Just how well does ATAG's i28C stack up against its rivals in the combi boiler market?
Let's compare it to some popular alternatives you might be considering.
The i28C really holds its own when it comes to efficiency, matching Vaillant's ecoTEC Pro at 94% – that's the highest in our comparison group.
You'll also find it offers a more generous hot water output than the Navien NCB 28, delivering 30.3 kW compared to 27.7 kW.
Where the ATAG truly shines is its warranty coverage.
While Baxi matches its 10-year standard warranty, only ATAG gives you the option to extend it to 14 years.
That's quite a vote of confidence in their product's reliability.
The unit's compact size means it'll fit nicely in your kitchen cupboard, making it as practical as it's efficient.
For those interested in exploring alternatives, our extensive collection of Vaillant boiler guides provides detailed comparisons and specifications.
