Baxi 800 Combi Boiler Performance and Efficiency
While many boilers claim impressive stats, Baxi's 800 combi boiler truly delivers with its outstanding 93% efficiency rating and ErP A-rating for both heating and hot water. You'll notice the difference in your energy bills, thanks to its advanced condensing technology that captures and reuses heat that would otherwise go to waste.

|---|---|---|
| 825 | 10.2 L/min | 20 kW |
| 830 | 12.2 L/min | 23 kW |
| 836 | 15.0 L/min | 25 kW |

Whether you're running a quick shower or heating the whole house, it'll maintain peak efficiency. Plus, with the built-in frost protection and easy-fill system, you won't need to worry about maintenance headaches during those chilly winter months.
Baxi 800 Combi Boiler Pros and Cons
Making a smart choice about your home's heating system requires weighing both benefits and drawbacks carefully. The Baxi 800 Combi brings impressive features to the table, but it's not perfect for everyone.
You'll appreciate these key advantages and limitations:
- 93% efficiency rating that'll help shrink those heating bills
- Compact design that fits neatly in a standard kitchen cupboard
- Generous 10-year warranty for peace of mind
- Limited hot water flow when multiple taps are running
- Higher upfront cost compared to some competitors
While the Baxi 800's efficiency and space-saving design make it an attractive option for small to medium homes, you'll want to think twice if you've got a large household with heavy hot water demands.
The included magnetic filter helps protect your investment, but remember you'll need a Gas Safe engineer for installation to keep that warranty valid.
How Does The Baxi 800 Combi Boiler Compare To Similar Models From Other Manufacturers?
When comparing today's leading combi boilers, you'll find the Baxi 800 holds its own against premium competitors like the Worcester Bosch 8000 and Vaillant ecoTEC Plus.
While the Baxi 800's 93% efficiency rating is slightly lower than its rivals' 94%, it makes up for this with its compact size and affordability. You'll appreciate its smaller footprint if you're working with limited space – it's remarkably slimmer than both the Worcester and Vaillant models.
The Worcester 8000 offers higher flow rates and fancy features like a touchscreen display, but you'll pay a premium for these bells and whistles.
The Vaillant ecoTEC Plus sits between the two, offering quiet operation and excellent efficiency.
However, the Baxi 800's included magnetic filter and competitive 10-year warranty make it a smart choice for value-conscious homeowners.
How Much Does A Baxi 800 Combi Boiler Cost?
Looking to budget for a new Baxi 800 combi boiler?
You'll find these reliable units sit in the mid-range price bracket, with costs varying by model size. The standalone boiler prices start at £1,161 for the 24kW model and go up to around £1,550 for the more powerful 36kW version.
When you factor in professional installation, you're looking at a total investment of £2,000-£2,500. This includes essential extras like magnetic filters and flue components.
- 824 model (24kW): £1,161 – £1,212
- 830 model (30kW): £1,308 – £1,390
- 836 model (36kW): £1,450 – £1,550
- Installation costs: £500 – £1,000
- Additional components: Around £300
While it's pricier than the Baxi 600 series, you're getting better features and a longer warranty for your money.
Plus, these prices are quite competitive compared to similar models from other manufacturers.
Baxi 800 Combi Boiler Warranty and Service Support
The Baxi 800 combi boiler comes with one of the most extensive warranty packages you'll find in today's market – a full 10-year parts and labour guarantee.
