Where Should I Put My Boiler?

For many homeowners, when they are looking to have a new boiler installed, they prefer to install it in the place where the old boiler was. However, if the new boiler is a bigger or a different type, this isn’t always possible. Also, in some instances, homeowners want to change things up. But this is easier said than done especially because there are boiler installation regulations to be followed.

To help make it easier for you, below is a quick guide of where you can install your boiler and be assured of efficiency and safety.

Choose a wall location

First and foremost, the boiler should always be installed on a wall that is strong enough to support its weight. Usually, this is the external wall since they are made the strongest in comparison to divider walls in the house. With a strong wall, you are assured the boiler will not become loose with time and pour hot water around the house.

Additionally, you’ll also need to let the flue pass to the outside of the house easily. This is easily done when the boiler is installed on the external wall. Flue location and clearance is covered in the building and boiler installation regulations. The regulations define a minimum distance the flue should be installed from air bricks, windows and other building outlets. This regulation is necessary to ensure the harmful gases don’t find their way back into the house.

Another important consideration to be made is the installation of the condensation pipe. This pipe carries waste and acidic water from the boiler into the drainage system. Given that it drains into the main drainage system, it should be located outside the house. And to prevent the wastewater from freezing during winter, it’s essential to insulate the pipe.

Easy access

Though boilers are made to last long, they can last even longer with regular maintenance and servicing. Because of this, you need to install the boiler in a location that it will be easier for the Gas Safe engineer to access it for maintenance. The engineer should access all parts of the boiler without having to assume awkward and harmful positions.

You can install the boiler inside a cupboard provided it’s big enough for a Gas Safe engineer to reach various parts. Because of this, a walk-in bedroom cupboard will work just fine. But with bedroom boiler installations, you need to install a carbon monoxide detector. Carbon monoxide is a by-product emitted by a running boiler. It is colourless and odourless. Over the years, it has been responsible for the death of some homeowners. To improve your safety, this detector is essential.

Also, depending on the nature of your property, you can install the boiler in the outhouse o garage. But for these locations, you’ll want extra boiler protection against the cold.

And last but not least, you can place the boiler in the kitchen or the bathroom. However, there are still some regulations regarding wiring that you need to adhere to. These regulations help to protect the boiler and wiring from moisture and steam.

If you intend to install the boiler in the loft, you need to ensure the loft is accessible and is well lit for safety.


Always choose a Gas Safe boiler engineer to install your boiler. This way, even if you are unsure of the finer installation details, they will guide and ensure boiler installation regulations are met.
