What Do The Experts Have To Say?

I have never had a problem installing a Baxi boiler. I’ve pretty much fitted them all – from the Platinum to the 400 Heat, the Avanta and now the new one, the 600 Combi. What you always get – no matter which boiler you fit – is reliability. I’ve had great feedback from my customers on how hard-wearing they are. And, if there is ever a problem, the back-up support is excellent. Help is always at the end of the phone, whatever the question. I started with the Avanta and couldn’t believe how quiet they were compared with other manufacturers’ boilers. I particularly like the built-in stand-off frames and it, too, is so quiet. What I like about the trainers is that the approach is so laid-back. It’s not high-pressured at all, so I don’t feel like I’m being sold to, just benefiting from these guys’ expert knowledge. Training has always been readily available, so I can feel confident when in a customer’s home. Their recommendation today of the new IFOS weather comp in the flue is going to be really useful for me come 6 April when the Boiler Plus legislation comes in. They’ve just got it all covered!

Feedback – For the last 12 years, since I have a boiler with BAXI, Jamal is the best engineer that I had to fix the issue. he was on time, efficient and friendly. I really appreciated his professionalism when calling me this morning and giving me an estimated time of arrival. Previous engineers did not offer the same courtesy..
Huge thank you to Jamal
Merry Christmas!

Feedback – Quick, polite, and outstanding service! The engineer was incredibly friendly and he told us where the problem in our boiler was. He was originally told by another engineer sent by SSE to replace the heat exchanger but when we told him what the issue was, he immediately knew the problem was somewhere else. Needless to say, the service was quick, efficient, and now we have our boiler working just before Christmas. If I could give more than 5 stars, I definitely would!

I had a problem with my boiler. The boiler is Still under warranty. Customer service when ringing was fantastic. They got an engineer booked for the next day. The engineer came when he said. Great service. clean efficient and knowledgeable and fixed the fault quickly …I had the yearly service done at the same time. I’m very happy with the service from all the staff at Baxi thank you so much. Their Platinum boilers with the warranty are a great buy.
Merry Christmas to you all at Baxi and best wishes for 2021.

Real World Use Case:

Our boiler was about to break down just before Christmas, a friend recommended this service because I was out of warranty. After placing my order, within the same day someone called me back to discuss the different options available to me – and the next day an engineer came round within the allocated time and fixed the problem quickly! I would highly recommend Baxi. Top quality product and excellent after care service – even on a boiler over 8 years old.

  1. How Old Is My Baxi Boiler?

To find out how old your boiler is, visit the official industry database. Fill in details of your boiler and the dates when the manufacture of that model began and ended will be displayed. You can search for all brands and models of boilers in this database. Or you can look at your boiler’s serial number. This can usually be found on the drop-down panel on the front. The serial number has all the information needed for us to tell you when your boiler was manufactured. Contact us with the details.

2.What is Water Treatment? How to Keep Your Heating System Healthy

Buying a new boiler is a big investment, and not taken lightly, whether it’s a distress purchase because your old boiler has broken down and can’t be repaired, you have extended your home and need a bigger boiler to cope with more radiators or you are concerned about your carbon footprint and want to be more energy-efficient.

3.What should the pressure gauge on my boiler be reading?

The normal operating water pressure for your boiler and central heating system is between 1.0 and 2.0 bar. If the pressure drops below 1.0 bar, you need to repressurise it. If the pressure goes above 3.0 bar, you will see water coming from the pressure relief valve (usually on an outside wall). You can reduce the pressure by bleeding a radiator or draining some water out of the system using a drain point, usually found underneath a radiator.

4.How Energy Efficient Is My Boiler?

As one of the biggest costs for householders in the UK, it is worth understanding how energy efficient your boiler is, and how much you could save if you replaced it with a new high-efficiency model. In April 2018, the Building Regulations changed again, requiring all new boilers to be at least ErP 92% efficient.


After finishing the above article, all you can know is, Baxi 600 Combi boilers are not the best yet the most reliable boiler brand available in the market. The overall score is very medium but it is equally price-worthy and it has no competition regarding the durability as well as affordability with other boilers. However, do check with your local engineer before jumping onto any decision before buying a boiler. The engineers are the subject matter expert hence, they can tell you more clearly and properly. They will suggest you after listening to your requirements and observing the size of your house and according to the budget.
