Baxi Combi Boilers Prices From £451 to £1,282
Condensing combi boilers are the perfect space-saving option.
That’s because you don’t need a hot water cylinder or a cold-water tank.
Instead, the combi simply heats water on demand.
That means that when you turn on your hot water tap or turn up the heating thermostat, the combi comes to life and begins to heat the water.
Baxi 200 Combi Boiler Prices From £455
The Baxi 200 combi could be an excellent addition to your shortlist if you have a smaller home or apartment.
It’s available with two different heating outputs, 24 kW and 28 kW, with your choice likely to depend on how many radiators you have in your home.
With efficiency levels of 89%, it joins the models in the top tier of boilers that use less energy to heat your water and, in return, keep your gas bills lower.
The Baxi 200 also has nifty features, including an integral frost thermostat.
That means you will not come home to find frozen pipes and a boiler that won’t start.
Then there’s an LCD display that shows you strictly what temperature the boiler is operating at, along with any status or fault codes.
This is a boiler that is compatible with the uSense smart thermostat.
Just download the app onto your mobile phone and know that you have complete control of the heating system no matter where you are.
You can also use the app to monitor your energy use and set timers for when your heating should go on and off.

Baxi System Boilers Prices
When you need to have hot water coming from multiple outlets simultaneously, you might find that a combi boiler just can’t cope.
That’s then going to mean that someone will get a lukewarm water supply rather than a hot one. A system boiler can cope with these types of situations.
The heated water is stored in a hot water cylinder, so that means that it’s available to use whenever you need it.
The built-in pump can supply hot water so that you can enjoy a hot shower, even if someone else is using hot water in the kitchen.

Baxi Regular Boilers Prices
A regular boiler forms part of the heating system as there also needs to be a small expansion tank and a larger cold water storage cistern, both of which are typically positioned up in the loft.
Then you’ll also have a hot water storage tank and a pump that forces the hot water around the home.
It would be unusual to choose a regular boiler to replace a combi or system boiler, and that’s because of all those additional requirements.
However, if your home already has a regular boiler fitted, then it might make sense to just replace the boiler with a newer, more efficient model.
Also, if you have low water pressure and multiple bathrooms, this can be another time when a regular boiler can be a good option.
One of the key benefits of the regular boiler is that you can have several hot water taps on simultaneously without any problems.
So, for busy families with several bathrooms, it can make sense to stick with a regular boiler.
Baxi 400 Regular Boiler price From £494
The Baxi 400 is a great option for where you need to keep a close eye on energy bills.
That’s because it has an efficiency rating of 93%, which gives it an ErP A rating.
In addition, the 400 is available with a range of power outputs, including 12, 15, 18, 24, and 30kW. That means that it’s likely to be suitable for small to medium-sized homes.
The 400 is small enough to fit into a kitchen cupboard, and it comes with options for both rear and top flue, making it a quick install when replacing an existing regular boiler.
The design also makes maintenance easy, with both side and front access to all the key components.
Great if you want to move a boiler to a tight space in your home.
We like the quiet operation of the 400, which makes fitting it into the kitchen a real option.
The 15kW version, for example, operates at 33dB.
If you are wondering how that compares to day-to-day life, well, when we whisper, that’s around 30dB, while you could expect a quiet library to have background noise of about 40dB.
The Baxi 400 comes with five-year parts and labour warranty.

Baxi Back Boilers
Baxi back boiler prices are no more. Replacing a back boiler with another back boiler is illegal due to inefficiency.
The best boiler to replace a back boiler is a combi boiler and most combi boilers are powerful enough for homes with a Baxi back boiler.
Baxi Bermuda BBU
The Baxi Bermuda back boiler unit was one of the best-selling back boilers ever. At the time, it was innovative and energy-efficient.
As time passed and technologies improved, combi boilers gradually became affordable and when gas condensing technology was invented became the go-to heating system.
Who Are Baxi?

Baxi Boiler Warranties
We’ve listed the Baxi boilers warranty available for each boiler and their price in the tables below. With the period of cover ranging from 2 years up to 10 years.
This will be important to check out before you commit to a particular model.
If you find the perfect model for your needs but the warranty is a little lacking, you can always take over the boiler cover to ensure that emergency repairs are covered like annoying error codes that crop up like the E1 error code for low boiler pressure.
Some plans even include an annual Baxi boiler service to provide complete peace of mind cover.
A new boiler is a significant expense. That means that you want a warranty to give you protection against what can be expensive bills for both labour and repairs.
The length of the warranty on offer does vary between different models, but at the upper end, you could get a 10-year period of cover.
As with all boiler manufacturers, there are requirements that you need to meet to ensure the validity of the warranty. These include:
- Registering the warranty for the boiler within 30 days of installation
- A Gas Safe registered engineer carrying out the installation
- Completion of the Benchmark commissioning checklist after installation.
- Annual servicing of the boiler, which a Gas Safe must complete registered engineer
If any of these four requirements are not met, then there is a risk that Baxi will reduce the warranty to just 12 months!
