Rest assured, that Baxi will have a replacement boiler quote for your home no matter the size and location, as they can even accommodate LPG systems should you require this. However, today we will be looking at the Baxi 630 Combi Boiler.

Even according to the most up to date Which? Magazine reviews, Baxi scored a highly respectable 74%.

This is a higher score than Ideal or other comparable companies in the market. These reviews were from both customers and gas fitting engineers.

The Baxi 600 Range of Combi Boilers:

baxi 600 range review

The Baxi 600 Range has a boiler that will suit many types of homes. The Baxi 630 which we are currently looking at will be good for homes with around 1-3 bedrooms and up to 2 bathrooms. 

If you have a bigger home, the Baxi 636 may be a better choice for you and suit your needs. 

No matter which boiler in the range you choose, they all have similar efficiency ratings as well as the same size. The only real difference is the KWH outputs.

The Baxi 600 Range comes in 15KW, 18 KW, 24 KW, 30KW, and 36KW. You can also find LPG versions of the Baxi 600 Boilers which are available as both System and Combi Boiler options. 

Compare the Baxi 630 and Customer Reviews

Baxi 630 Combi Boiler Reviews are overall quite positive from a customer’s point of view. Many people talk about the compact design, quiet operation, and availability of engineers to fix any issues. 

The included features are competitive compared to other boilers on the market and the adaptability with additional options are impressive. 

In terms of other reviews and tests, Which? Gave the Baxi brand a respectable score of 74% as mentioned in the introduction. 

This is good, however when you compare this to other brands such as Worcester-Bosch at an incredible 90% satisfaction and quality review, then it seems to pale in comparison. 

With its rear piping as standard, easy-fill loop, and other features which make fitting and servicing easier, we think that the Baxi 630 is actually a better boiler than many others available in a similar class. 

Screwfix, for example, has a 5/5 rating on the Baxi 630 Boiler from actual customers so do your own due diligence and see which boiler suits you the best for your particular home. 

One review from february 2020 states:

“An amazing compact design boiler with the great addition of being able to take pipework behind the boiler without needing to space the boiler off the wall. Easy to use for any age of the customer and all-round a great boiler.”

Baxi 630 Review Conclusions and Recommendations:

baxi 630 review

Although we know there are better overall boilers on the market, the
Baxi 630 has a few features which even the Worcester-Bosch and Vaillant boilers don’t have. 

These are features such as the stainless steel heat exchanger, brass and copper parts, piping going into the back and especially the opentherm feature. 

Opentherm means that you can install a digital nest thermostat easily and make use of all the advanced features whereas Worcester-Bosch and Vaillant do not have this automatically integrated.

How much does a Baxi 630 combi boiler cost?

The Baxi 630 is the mid-range boiler in the 600 range. It is also Baxi’s mid-range boiler in all of its ranges between the Baxi 200 and Baxi 800 boiler ranges. This means that the cost of a new boiler in the 600 range are reasonably priced and available to most homes in the UK

Expect to pay around £2,000 for Baxi 630 including full installation by a Gas Safe registered heating engineer.
