Baxi 800 System Boiler Performance and Efficiency
When it comes to performance and efficiency, the Baxi 800 System Boiler truly shines with its impressive 93% efficiency rating. You'll benefit from its ErP A-rating and innovative condensing technology that captures and reuses heat that would otherwise go to waste.
| Feature | Specification |
|---|---|
| Output Options | 18kW or 24kW |
| Max Radiators | Up to 15 |
| System Capacity | 100 litres |
The 24kW model is perfect for medium-sized homes, and you won't need to worry about finding space for it – the compact design fits neatly into a 290mm deep cupboard.

Baxi 800 System Boiler Pros and Cons
The Baxi 800 System Boiler's impressive performance features tell only part of the story. When you're weighing up your options, you'll want to evaluate both its strengths and limitations.
On the plus side, you'll get excellent coverage with a 10-year warranty for parts and labour, and the compact design will slip right into your kitchen cupboard. The built-in magnetic filter and OpenTherm interface add real value, while the easy-fill loop makes maintenance a breeze.
However, there are some trade-offs to evaluate. You'll need to dig a bit deeper into your pocket upfront compared to other models, and you'll have to stick with a professional installer.
The limited output options (18kW and 24kW) mightn't suit every home, and repairs could be tricky due to the advanced technology.
How Does The Baxi 800 System Boiler Compare To Similar Models From Other Manufacturers?
As you're shopping around for a new system boiler, you'll find the Baxi 800 faces some stiff competition from industry heavyweights like Worcester Bosch's Greenstar 8000, Vaillant's ecoTEC plus, and Ideal's Logic+ system boilers.
While the Baxi 800's 93% efficiency rating is slightly lower than its competitors' 94%, it's still an A-rated system that'll keep your energy bills in check.
You'll get good value with Baxi's competitive mid-range pricing, especially compared to the premium-priced Worcester Bosch and Vaillant models.
The Baxi 800's 7-10 year warranty mightn't match Worcester's 12-year offering, but it's on par with Vaillant and Ideal.
Where Baxi really shines is in its installation simplicity and maintenance access, making it a practical choice that won't give your heating engineer headaches.
