How Long Does It Take To Fit A New Boiler? how long to install a new combi boiler

One of the most common questions people have when considering whether they should get a new boiler is how long installation will take. But asking how long does it take to fit a new boiler is actually a very difficult question to answer!

Yes, this isn’t the answer most people will want but boilers are often quite complicated and not everything is simple (just like life really).

So, let’s get right down to it how long does it take to fit a new boiler?

In this guide, we’ll be examining everything that can impact the timeframe for the installation of a new boiler.

We’ll also be looking at some of the most frequently asked questions as well. If you want to get a new boiler installed you will probably want it done quickly but boiler installation can vary wildly.

Let’s find out exactly why that is and look at everything you need to know when it comes to finding out how long it takes to fit a new boiler.

So, how long does it take to fit a new boiler? Well, the first thing that will impact the timeframe is exactly what kind of boiler you want installing.

Are you swapping your standard boiler for a very similar or like for like model?

If so then installation will usually take 1 to 2 days. Yes, that might seem like a lot of time but boilers are complicated machines and there is a lot of variation to this.

Some installations such as a combi swap can take as little as half a day or 4 hours but this depends on if you are moving your boiler.

Sometimes you may need extra pipe work relocating or a boiler flue relocation and all of these jobs are not quick fixes. 

If your boiler was previously leaking water then you may need some work to repair flooring or areas that water may have dripped on to. 

Boilers such as the Megaflo unvented range takes longer to install as many of these installations are new installs. These can take 1 to 3 days dependent on the size of the boiler and home. 

Basically, it will often take quite a while however if you have a combi boiler then you will benefit from a much shorter installation time.

So, let’s change the question for a moment how long does it take to fit a new boiler if it’s a combi unit?

Combi boilers or combination boilers to give them their full name are a hybrid appliance that operates as both a central heating unit and a high-efficiency water heater.

These are more modern boilers and they benefit from much shorter installations on average.

A combi boiler can usually be installed within 4 – 6 hours which is good news, especially when compared to the on average longer installations for more “traditional” conventional boilers.

However, you can only benefit from this shorter installation if you are swapping out a pre-existing combi boiler and want it installed in the same place. Find out what a conventional boiler is here

If you are getting a combi installed but currently have an older boiler, such as a traditional back boiler, then installation will take longer and if you want the location of the boiler changing then installation will again take more time.

The location is very important when it comes to boiler installation so let’s take a more detailed look at it.

When considering how long it will take to fit a new boiler the location will be very important to any engineers or surveyors estimate.

If you want the boiler to be kept in the same location then installation will almost always be quicker, unless the engineer runs into an unexpected problem that is.

However, if you want the boiler moving to another location (maybe to get better Feng Shui) then you are going to have a very different answer to the question of how long does it take to fit a new boiler.

Moving a boiler to a new location will usually require the engineer to change the existing pipework and maybe even install new pipes as well.

This as I’ am sure you can guess will add some extra time to your boiler installation. How much longer this will take can once again can vary quite considerably depending on where you want the boiler moving to.

But on average you can expect it to add half a day to a full day of extra-time to your boiler installation.

Finally, the other main thing that can impact your installation timeframe is whether you are getting a system upgrade or not.

If you’ve never heard the term system upgrade before then don’t worry I’ll explain, it basically means you are changing the type of boiler.

We already talked about combi boilers earlier but if you have an older conventional boiler and are getting a new combi boiler installed you can still expect the standard 2 days for installation.

However, if you already have a combi boiler and are replacing it with a more conventional boiler then installation could take even longer at around 3 – 4 days in some cases.

So within a few hours your can be controlling your heating and room temperature with your phone or tablet if it is a combi combi swap or longer dependent on your current boiler system.

So, how long should it take to fit a new boiler?

Well, there are many different answers as you’ve seen me explain but in most cases, you can expect around 1 day on average. Unless you are swapping a combi boiler for another combi unit in which case it will be much quicker.
