How Long Should a New Boiler Installation Take?

A question that is often asked is: how long does it take to fit a new boiler in your home? While it may seem like there is a straightforward answer, there are a few factors that will affect how long it takes to fit a new boiler. 

What does a new boiler installation involve?

Before your new boiler is even installed, you can expect to have a visit from a Gas Safe Engineer to inspect the area in which the boiler is located and discuss with you what boiler setup will work best. 

On the day of the installation, the engineer will ensure your space stays clean by covering up nearby surfaces. If you are having your old boiler replaced, it will first be cut off from the gas and water supply. 

Before connecting the new boiler, your central heating engineer will flush out your central heating system to remove most of the debris inside. Next, they will adjust the pipework, potentially reconfiguring it to minimise the heat loss to your boiler.

Finally, your engineer will install your boiler at the location you agreed on, connecting it to the water outlets, the mains supply and radiators. If necessary, they will also fit the water tank too. 

How long does it take to install a new combi boiler?

A combi boiler doesn’t take too long to install, and it will usually be completed within 4 to 6 hours. 

However, if you wish to replace an older, different boiler with a new combi boiler, this may take 1 to 2 days to complete since there is a lot more work involved to change a conventional system to a combi system.

How long does it take to install a new system boiler?

Depending on what type of boiler you have before the new system boiler, it can take up to 2 days to install a new system boiler. 

It can be quicker than 2 days; for example, if you already have a system boiler it will take around 1 day, but heating engineers may need to take a considerable amount of time to do some mild structural work or pipework. 

How long does it take to convert a conventional boiler to a combi boiler?

Converting a conventional boiler to a combi boiler may take 2 to 3 days to complete since the new combi boiler will require different electrics and plumbing.

Time will need to be spent removing the unnecessary tanks and cylinders, stripping away any extra pipework and tidying up afterwards.

How long does it take to move a boiler to a new location?

The time it takes to move a boiler to a new location depends on where it is being moved to. It would take at least 2 days for a simple move because of all the pipework that needs re-running and the position of the new flue. 

Not only does it involve changing the way in which the pipes flow, but if you are having a new boiler installed at the same time, it will also involve changing the electrics and plumbing to suit the needs of the new boiler type. 

How long does it take to install a boiler with a new fuel type?

If you’re getting a new boiler but changing the fuel type, it can take around 2 to 3 days to complete since there will be extra plumbing and electrical work to be done. 

For example, if you’re switching from a gas boiler to a new electric boiler but keeping it in the same position, time will be added on in the installation process. You may even need to have some upgrades to your electrics which would need to be carried out by a qualified electrician. You should get this assessed before you go ahead and purchase a new electric boiler.
