Baxi 600 Warranty Period
The warranty period is an essential consideration when purchasing any new boiler, whatever the brand, since it is the period you are offered protection in the unfortunate event that something goes wrong.
Therefore, the longer the warranty period the better, a lengthy warranty period is also often considered a sign of quality.
Baxi offers a no-quibble 7-year warranty on their Baxi 600 model, which is pretty much standard in the industry. Yet, a brand like Worcester Bosch offer a 10-year guarantee (when you purchase via Heatable), which is an additional 3 years cover and also a guarantee, superior to a warranty.
...a guarantee is an agreement from the manufacturer that they will attend your property and repair or replace the boiler. A warranty is an agreement to investigate the problem (and not necessarily fix it for free
Baxi 600 Combi Boiler Prices
To bag yourself a Baxi 600 combi boiler, expect to pay between £700 and £1000 (but that is for the boiler only).
Baxi are not a 'premium' boiler manufacturer. They're very much in the budget bracket.
If you purchase a Worcester Bosch boiler through Heatable, our fixed price offer includes both the boiler and complete installation.
Prices for the Worcester Bosch Greenstar Compact range begin at £2,095 and are available with 0% APR (over 2 years). Get your fixed price here.
Baxi 600 Efficiency
The Baxi 600 combi boiler is a high efficiency boiler which is A-rated, offering 93% efficiency, this means that 93% of the fuel used is converted to heat.
Boilers over 10 years old are typically G-rated, meaning they provided only 70% efficiency with 30% of the energy burned being wasted, for example, via the exhaust fumes.
According to the Energy Saving Trust, you could save as much as £340 a year by replacing an old G rated boiler with a modern high efficiency A rated model. That's almost the 1/3rd of the cost of an iPhone.

Some of the 600's good bits
In the event that your boiler's pressure drops, it is usually possible to increase the pressure via the pressure gauge, however for many homeowners, their design makes them difficult to use.
Baxi responded to that feedback by introducing the EasyFill feature. This is a spring-loaded single lever, which is extremely user-friendly, you simply press down on the green lever and wait until the needle reaches the green area within the pressure gauge.
uSense Smart Room Thermostat
The Baxi 600 can partner with its very own uSense smart room thermostat.
Easily controlled via an accompanying smart phone app, the thermostat has a range of innovative features including temperature modulation and temperature scheduling.
From the uSense thermostat you can also activate antifrost protection during cold weather to protect your boiler from frost and prevent it from freezing during the winter months.
The energy consumption feature also allows you to see how much energy your system is using, allowing you to better understand where efficiencies or use could be improved.

Baxi 600 Compact Range vs the Worcester Bosch CDi Compact
The Baxi 600 combi boiler and the Worcester Bosch CDi Compact boiler are both very similar in that they are both extremely efficient, available in a variety of sizes and are compact boilers, designed to be housed in small spaces e.g. kitchen cupboards.
However, for several reasons we recommend the Worcester Bosch CDi Compact over the Baxi 600, these include the following:
Which Best Buy Award winner for 10 consecutive years
Which? Is a reputable consumer advice organisation that carries out thorough testing and impartial reviews.
So it’s a pretty big deal that Worcester Bosch has won the award 10 years in a row, receiving several high 5-star ratings the consumer choice organisation considers most important to consumers, including full marks for their build quality and availability of parts and spares.
Unfortunately, to date, Baxi boilers have an overall Which? score of 54%
A 10-Year Guarantee not just a “warranty”
Most major boiler manufacturers offer a warranty, but Worcester Bosch offers a guarantee instead.
Sounds like a blag, what's the difference?
A guarantee is an agreement from the manufacturer that they will attend your property and repair or replace the boiler within a reasonable amount of time.
Most other boiler manufacturers just offer a warranty as standard, this is an agreement to investigate the problem, but is not an unconditional agreement to fix or repair it for free.
Availability of parts
Worcester Bosch has earned themselves an industry-wide reputation for having parts that are very easy to source in the UK, which is extremely handy if you want your boiler fixing quickly.
Baxi 600 Combi Boiler Conclusion
If you are on the hunt for one of the best compact boilers, ideal for a small space, that’s energy efficient, then we recommend the Worcester Bosch Greenstar CDi Compact.
Why? It has been a Which? Best Buy winner for 10 years in a row and with Heatable comes with an exclusive 10 year-year guarantee, that is 3 extra years and beats the measly warranty offered by Baxi.
To get the best price on a Greenstar CDi compact, or Greenstar i boiler, buy from Heatable.
