What Happens on Your Boiler Installation Day?

Having a new boiler installed can feel like a big job, but knowing what to expect can make the process much less daunting. From preparing your home to switching the new boiler on, your heating engineer should keep you informed throughout the installation.

Whether you’re replacing an old boiler or arranging one of the many boiler installs available today, here’s what typically happens on installation day.

1: Your Engineer Arrives and Gets Set Up

The day will usually start with your heating engineer arriving at the agreed time and talking through the installation process with you.

Before any work begins, they may confirm where the new boiler will be installed, discuss any access requirements and explain what work will be carried out.

Your engineer will also take steps to protect your home, such as using dust sheets and floor protection around the working area.

2: The Old Boiler is Removed

If you’re replacing an existing boiler, the first major job is removing the old appliance.

Your engineer will safely disconnect the boiler from the gas, water and electrical connections before removing it. Depending on the location and type of boiler installs, this can sometimes involve removing pipework or making adjustments to the existing system.

The old boiler will then be taken away for appropriate disposal.

3: Preparing for the New Boiler

Before the boiler installs process begins, your engineer will prepare the area and make any necessary changes to the existing heating system.

This could include:

• Updating or replacing pipework
• Installing a new flue
• Preparing the wall for the new boiler
• Upgrading the controls
• Installing or replacing filters and other system components
• Making sure the existing heating system is suitable for the new boiler

All boiler installs are slightly different, so the exact work will depend on your home and the type of boiler being installed.

4: The New Boiler is Installed

Once everything is prepared, the new boiler can be fitted into position.

Your Gas Safe Registered engineer will connect it to the heating and hot water system, gas supply and electrical supply, as well as fitting the new flue and controls where required.

They’ll make sure all connections are secure and that all boiler installs meet the relevant safety requirements.

5: The Heating System is Checked and Tested

With the boiler installed, your engineer will carefully test the system before handing it back to you.

This includes checking that the boiler is operating correctly, testing the heating and hot water, checking for leaks and making sure the flue and safety controls are working properly.

The system may also be balanced or adjusted to help your new boiler perform efficiently.

6: Your New Controls Are Set Up

Modern boilers often come with advanced heating controls, thermostats or smart controls.

Once boiler installs are complete, our engineer should show you how these work and help set them up to suit your household.

Don’t worry if the controls look complicated at first. Your installer should explain the basics, including how to adjust your heating, change the temperature and set a heating schedule.

7: The Installation Area is Cleaned

Once all the boiler installs work is finished, your engineer should tidy the working area and remove any packaging, old components and installation waste.

A professional installation shouldn’t leave you with a mess to deal with once the engineer has gone.

8: You’ll Be Shown How Your New Boiler Works

Before leaving, your engineer should talk you through your new boiler and answer any questions you have.

They can explain things such as:

• How to use the controls
• How to adjust the heating and hot water
• What the boiler pressure should be
• What to do if an error code appears
• How to reset the boiler if necessary
• When your boiler needs a service

You’ll also receive the relevant paperwork and information about your boiler’s guarantee and servicing requirements. Should you need anything from us after your installation, or simply have a few questions, feel free to get in touch with us here.

Frequently asked questions

How Long Do Boiler Installs Usually Take?

The time needed for a boiler installation depends on the type of boiler, its location and whether any additional work is required.

A straightforward boiler replacement can often be completed within a day, while more complicated installations may take longer. Your heating engineer should give you an estimated timeframe before work begins.

Will I Have No Heating During Boiler Installs?

Yes, your heating and hot water will normally need to be switched off while the old boiler is disconnected and the new one is installed.

Your installer should aim to get everything back up and running as quickly as possible, particularly during colder months.

There are a few simple things you can do to help the installation run smoothly:

• Ensure clear access to the boiler and surrounding area
• Move valuable or fragile items away from the workspace
• Make sure the engineer can access relevant radiators, pipework and controls
