Most modern homes will have a boiler, and they’re fantastic heating solutions for a property of any size. Whether you have a combi boiler or a heat only boiler, this device will be the central source of warmth for you and your family around the home.

A question I see asked a lot is ‘where do I install a boiler?’ It’s a fine question to be asking, as theoretically, you can choose anywhere you want. However, certain rooms and areas are better than others, and that’s where this post comes in!

So, here’s your boiler installation checklist – find the best room that meets the following criteria!


  • It can’t be too cold

Make the room as toasty as possible!

It goes without saying, but your boiler will need to be hot hot hot!

If you must install it in a colder area, like the garage or loft, consider adding some cold/frost protection. This is installed on the pipework and the boiler and ensures it won’t freeze over and possibly burst when the weather gets cold.


  • Ideally, it needs to be installed as soon as possible

Don’t hang about – make it as fast as possible

The boiler will provide heat to your house, warming those radiators and making even the coldest of days a little bit brighter. This in mind, you’ll have to choose a room that will give you the least hassle in terms of installation.

If there’s a room that you use all day, every day, then that wouldn’t be a good place to install a boiler. If you have a pantry room or a cellar, these are great places for boilers because they get very little foot traffic.

Think about the installation time too, and how quickly you need it done. A service such as Flame-On boiler installation will sort everything for you, so you don’t have to worry. Once you’ve chosen the right room – bearing in mind ease of installation – you’ll be good to go.


  • You must allow room for servicing and maintenance checks

It should be regularly checked, just like any other equipment

You’ll need to make your boiler relatively easy to access for repairs and maintenance checks. It’s no good sealing it off in a hard-to-reach area. It needs to be able to be reached without any hassle. So don’t have it fitted too high off the ground, or behind a load of clutter. Give it a little room to breathe!


  • The flue should be able to go outside


The boiler’s flue needs to be able to go outside, whether you route it through the roof or a wall. You need to be sure that your boiler placement complies with building regulations before you install it though. The flue must be a certain distance away from windows and neighboring buildings.


  • The wall needs to be able to handle a heavy boiler full of water

The wall needs to look sound, and be sound
Whatever wall you choose to mount your boiler on, be sure of its structural integrity. The wall needs to be able to hold a heavy weight for 365 days a year, without fail. The boiler must also be secured to an inside wall, not the outside. This is to protect it from the weather and any potential damage that could cause.
