It's available in various outputs from 24kW to 36kW, so you can match it to your home's specific needs.
The stainless steel heat exchanger guarantees durability, while the uSense smart thermostat compatibility lets you control your heating from your phone.
You won't have to worry about noise either – it's designed for quiet operation.
With a standard 5-year warranty and energy efficiency ratings of 'A' for both heating and hot water, you're getting a reliable performer that won't inflate your energy bills.
Baxi 400 Combi LPG Boiler Performance and Efficiency
Building on its smart design features, the Baxi 400 Combi LPG boiler delivers impressive performance numbers that'll make both your wallet and the environment happy. With an A-rating and 89% efficiency, you'll notice the difference in your energy bills.
| Feature | Specification | Benefit |
|---|---|---|
| Efficiency | 89% A-rated | Lower bills |
| Flow Rate (30kW) | 12.2 l/min | Strong showers |
| Flow Rate (36kW) | 15.0 l/min | Multi-task usage |
You'll get plenty of heating power with outputs ranging from 24kW to 30kW, perfect for small to medium homes.

Baxi 400 Combi LPG Boiler Pros and Cons
When weighing up the Baxi 400 Combi LPG boiler's merits, you'll find it's a bit like choosing between a sports car and a family saloon – there are clear trade-offs to reflect upon.
On the plus side, you're getting an energy-efficient boiler that'll slip into a standard kitchen cupboard thanks to its slim 290mm depth. The A-rating for heating and hot water means lower energy bills, while the 5-year warranty offers peace of mind.
However, there are some limitations to reflect upon. With only one output option (28kW) and a maximum hot water flow rate of 11.5 litres per minute, it's best suited for smaller homes. The plastic components might raise durability concerns compared to metal alternatives.
Installation's a breeze though – at just 26kg, your engineer won't need a chiropractor appointment afterward!
How Does The Baxi 400 Combi LPG Boiler Compare To Similar Models From Other Manufacturers?
As you shop around for an LPG boiler, comparing the Baxi 400 Combi against its rivals reveals some interesting trade-offs.
While it offers solid performance at a mid-range price point, other manufacturers bring their own advantages to the table.
The Worcester Bosch Greenstar 8000 Life stands out with its impressive 12-year warranty and higher output options, though you'll pay more for these benefits.
Vaillant's ecoTEC plus operates more quietly and offers an extendable warranty up to 10 years, while the Ideal Logic Max matches the Baxi's compact size but with a longer 10-year warranty.
The Baxi 400's 11.5 L/min flow rate is lower than some competitors, but its A-rated efficiency and compatibility with smart controls make it a worthy contender, especially if you're working with a modest budget.

How Much Does A Baxi 400 Combi LPG Boiler Cost?
The Baxi 400 Combi LPG boiler hits a sweet spot regarding affordability for homeowners watching their budget.
You'll find the boiler unit itself priced between £630 and £730, with the 24kW model at the lower end and the 28kW version slightly higher at around £690.
When it comes to installation, you'll need to budget between £1,900 and £2,500 for the complete package.
This might make your wallet a bit lighter, but it's actually quite competitive for an LPG combi boiler with a 5-year warranty.
The final cost depends on a few key factors.
If you're moving the boiler to a new location, expect to add £250-£300 to the bill.
Similarly, switching from a different heating system type or adding smart controls like the uSense thermostat will bump up the price.
