Updated: June 5, 2024

After you pick the right boiler for your home, comes the part of installing your new boiler. The first thing you would need to do is to find a professional installer. Someone who is a Gas Safe Registered heating engineer. 

Importance of proper installation for safety and efficiency

The installation of your boiler can take some stages. The first, being an inspection of the installation location in order to check how suitable the place is. Next comes the installation process which can take some time depending on the complexity of the job at hand. And finally, there will be a final inspection checking if everything is working as it is. 

Proper installation is a key element in the process. A professional installer can ensure that your boiler is safe to run and is working as efficiently as it should. 

Pre-Installation Steps – Boiler Installation Process

Assessment of the current heating system

The first thing to be done when installing a boiler is to assess the current heating system and try to determine how the job will be carried out. Your installer will check your pipes as well to see if they are in a good condition. This process can determine how long the job will take and what kind of tasks are involved. 

Determining the appropriate boiler size and type

Of course by that time, the boiler size and type will be determined as well. In most cases, people will just replace their current boiler with the same type. In other cases, different types might be needed. For example, swapping a regular boiler with a system boiler or combi to a system if a combi boiler can’t meet your home’s hot water demand. 

Inspection of the installation area for suitability

The location site would need to be prepared before the installation takes place. A survey of the place will be carried. The designated place will be checked for suitability, making sure the place is big enough to have a boiler installed. 

Clearing and cleaning the designated space

To grant easier access to your installer, it is recommended that you clean and clear the area of anything that might be in the way. The work can be carried much faster when the place of installation is well prepared. So make sure to remove any obstacles that might delay the job at hand.
