Back boilers were a great space saver and cheap to install, but in the modern world, they aren’t very efficient. Back boilers are fast becoming a thing of the past. But what do you do if your home has one?
If you have a back boiler fitted in your home, this guide will help you decide the best way to upgrade or remove your boiler system.
What is a back boiler?
A back boiler may be a system you have never heard of.
So, what is it?
A back boiler is an old style heating system. The most popular back boilers by far were the Baxi Bermudas. Almost every back boiler installed in an older home was a Baxi Bermuda.
The unit is fitted behind the fireplace in the home, and uses the heat generated to produce hot water that is used throughout the home.
They are fitted behind gas or electric fireplaces, but are also found behind open fires too.
The flue from the chimney is already in place, so installation was fairly simple and cheap for homeowners.
Although the boiler unit was tucked away, this system needs to have a separate water tank and hot water cylinder connected to it. These tanks are usually situated in the loft.

Should I replace my back boiler?
If you have a back boiler in your home, you’re probably already aware it is not an energy efficient or practical system. If the system was installed in the 60’s, 70’s, or 80’s, it is definitely time to upgrade your system and take advantage of the evolution in boiler technology.
Most boiler installers will advise you to replace your back boiler system and here are a few of the main reasons why:
- Replacement parts are difficult to obtain.
- They are not energy efficient.
- Fitting a new boiler system will save you money on your household bills.
- Your back boiler may be unsafe.
- Back boilers are no longer manufactured.
- Whilst back boilers are quite unsightly; a new boiler can be hidden in an airingcupboard or the loft to maximise your space and make your home more attractive.
- They do not meet the modern Gas Safety regulations.
- If you are selling your home, a new boiler is a great selling point.
Can I get a new back boiler installed?
Back boilers are no longer manufactured and are not a safe boiler system. Therefore, you won’t be able to have a new one installed in your home. However, there are many homes in the UK that still have one.
If your back boiler is broken, it’s unlikely you will be able to find the parts to repair it, and it will be very expensive.
A boiler expert is likely to suggest that you replace your boiler with a modern system that is safer, compliant with regulations, and reliable.

Removing a back boiler
If you are having a new boiler installed, it is important that the back boiler is removed professionally.
A Gas Safe boiler installer will need to remove your back boiler to ensure it is done properly and safely, and that all the pipework is disconnected.
As they are behind fireplaces, the removal process can be messy. Flooring and walls may become damaged, as the pipework may be embedded into your walls.
If the old boiler is left, it can be a real danger in your home because:
- The boiler will retain moisture and could create steam.
- If the boiler is not vented properly or filled in, it could cause an explosion.
- It could cause injury to you or your family.
- Corrosion of pipework.
- It is a fire hazard.
- It can cause structural damage to your home.

1. Replace your back boiler with a combi boiler
Although back boilers are known for being durable and can last longer than modern boilers, technology and safety guidelines have improved significantly, and back boilers just don’t meet these requirements.
Combi boilers are a popular choice for many homeowners when they need to replace their back boiler. They heat hot water and central heating for the home simultaneously, hence the name ‘combination’.
The benefits of installing a combi boiler are:

- A combi boiler will last around 15-20 years.
- Parts are readily available for combi boilers, unlike back boiler parts.
- They are exceptionally reliable.
- They are better for the environment, as you use less water as it is heated instantly.
- Choosing an A-rated boiler will save you money on your household bills.

It is then stored in a hot water tank until it is needed in the home. A boiler installer will be able to give you the best advice on which boiler will be best for your home.
