Ideal vs Baxi: Combi Boiler Comparison

Updated: 5th November 2021

No to gas boilers

An Ideal or Baxi are making some of the best combi boilers on the market.

So if you’re looking for a replacement combi boiler, you won’t do much better than them. But does one

The mid-range price offered by both manufacturers makes them an attractive compromise between top of the range and low budget. We've compared a Combi boiler from each brand to find out which brand comes out on top.

Is a combi right for my home?

Before installing an Ideal or Baxi combi boiler, you need to know that a combi is right for your home.

Combi boilers are compact units that heat water on demand. Meaning they don’t store hot water in a cylinder – a bonus if you’re trying to save space!

But this is only good news if your home has a single bathroom.

If you get a combi but home has two showers being used at the same time, the water pressure will drop. So homes with two or more bathrooms, would be better suited to a system boiler.

Does it matter which combi I pick?

Ideal and Baxi have plenty of combi boilers to choose between. But it isn’t a case of simply picking one at random or going for the cheapest. Your new combi boiler must suit the heating and hot water demands of your home.

To get that right you need to look at the output rating (otherwise known as the size of the boiler).

A boiler’s output rating shows its power. And combi boilers have two output ratings. One for central heating (CH) and another for domestic hot water (DHW). Both of these need to suit your home.

You can get an idea of the right central heating output for your home using the table below.

Radiators CH output
Up to 10 24-27 kW
10-15 28-34 kW
15-20 35-42 kW

Now you know what size combi boiler you need, you can look for a model.

The tables below show which ranges by Baxi and Ideal have a combi boiler suitable for your home:

Baxi range 24-27 28-34 35-42

Baxi vs Ideal

Now it’s time to put the combi boilers by Baxi and Ideal head-to-head.

We’ve compared a combi boiler from each brand for homes with up to 10 radiators and between 10-15.

To compare them, we’ve looked at each boiler’s:

  • Central heating output rating
  • Domestic hot water output rating
  • Efficiency
  • Hot water flow rate
  • Maximum warranty period
  • Potential cost (before adding on the price of installation)

We’ve also noted whether an LPG model is also available. This is only important to home’s that aren’t connected to the gas grid.

Up to 10 radiators

Baxi and Ideal give homes with up to 10 radiators plenty of choice. Almost all of their ranges have a suitable combi but we’ve picked out the Baxi 836 and Ideal Vogue Max C32.

Combi model Baxi 836 Ideal Vogue Max C32
CH output 26.4 kW 26 kW
DHW output 36 kW 32 kW
Efficiency 93% 93%
Hot water flow rate 15 l/min 13.1 l/min
LPG compatible No Yes
Max. warranty 10 years 10 years
Potential cost £1,096 £1,206
Other CH outputs 21.2 kW 18, 32 kW

10-15 radiators

The Baxi Platinum 40 and Ideal Vogue Max C40 can both heat homes with 10-15 radiators.

These boilers are very evenly matched – making a comparison challenging. The output ratings, flow rate and maximum warranties are all identical. However, you could say the Vogue Max C40 clinches victory thanks to being slightly more efficient. Ideal also offer an LPG version for off-grid homes.

Combi model Baxi Platinum 40 Ideal Vogue Max C40
CH output 32 kW 32 kW
DHW output 40 kW 40 kW
Efficiency 92% 93%
Hot water flow rate 16.4 l/min 16.4 l/min
LPG compatible No Yes
Max. warranty 10 years 10 years
Potential cost £1,276 £1,323
Other CH outputs 24, 28 kW 18, 26 kW

15-20 radiators

For larger homes with 15-20 radiators, neither Baxi or Ideal have a suitable combi boiler. So you will need to turn to Worcester Bosch who have the most powerful combi boilers on the market.

If your home also has 2 or more bathrooms then you could be better off with a system boiler over a combi. Rather than heating water on demand and sending it straight to the taps like a combi, system boilers store hot water in a cylinder. This allows them to meet higher demand for hot water without a drop in water pressure.
