Before buying a new boiler, people tend to ask two important questions: how much does it cost to buy a new boiler?

How long does it take to fit it? For this question, there is no straight answer because the answer depends on several factors.

In this article, we will discuss the key factors of installing a new boiler and how long it takes you to fit it.

How long does it take to install a new boiler?

It makes sense to ask this question because some people’s time is valuable, they need to know how much it will cost them. Frankly, installing a new boiler can take 4 hours to 4 days of work, depending on your boiler type, fuel, location, and complex installation process.

Installing a new boiler typically needs extra or quick fixes. For example, during the installation processes, the installer may need an extra pipework relocation. Usually, this type of work takes time due to its complex process.

Combi to Combi swap

Whether you want to replace your old combi boiler with a new one, install a new combi, or look for more heating efficiency, combi boilers are an excellent choice. Installing a combi boiler usually takes less than 6 hours, specifically between 4-6 hours.

Nevertheless, if you install a combi boiler with a non-existing boiler the installation time will take much more than 6 hours, it could expand to 1-2 days depending on the boiler type you used to have and its location.

Standard boiler to Combi swap

Here when things start to get much complicated and take a longer time to install or replace a standard boiler with a new combi boiler. Why is that?

Unlike combi boilers that are considered the simplest type, standard boilers are a bit complicated and because of that swapping from standard to combi takes time. Approximately 2 days.

To replace a standard boiler with a combi, the person who carries out the installation must go through a complex swapping process.

Because standard boilers work with a two separated water tank system, that requires removing the unnecessary water tank with additional pipework.

Well, there are advantages that you will benefit from swapping a system boiler to a combi boiler, and one of them is to retrieve the removed water tank space.

Back boiler to combi swap

Back boilers are considered relatively old they can survive up to 25 years. Upgrading a system of that age usually takes time. Removing the old back boiler, replacing it with a modern combi type, and installing it normally takes 2-3 days.

First things first, the location, it’s a physical test to remove a back boiler, it could take one day to only remove it from its place.

Swapping from back boiler to combi can be difficult and time-consuming for engineers because of several factors. The boiler age condition makes it hard for some engineers to work properly or find parts that could fit the new combi boiler. Plus, the engineer will probably have to eliminate any sludge, ruts, or debris from the back boiler through a power flushing.

And there is the pipework, in some cases if an old boiler has reached its final days, that usually requires installing a new piping system that fits the new combi.

But if you want to upgrade your system and install a new combi boiler in another place, that usually takes up to 5 days. The work will include, removing the old boiler, taking it out, installing the new boiler, installing a fitted piping system to the new boiler…

How does it take to change your boiler location?

Some people find it’s more suitable for them to relocate the new boiler after removing the old, maybe they want to gain extra space or relocate it in a more suitable place. Usually, installing and relocating a new boiler combi takes an additional day. For example, if you want to swap and relocate a back boiler with a combi boiler, the work is estimated to be done from 4-5.

Changing the place of your boiler means that the engineer will install and fit a new piping system in the new location.

Smart thermostat

Your heating system matters for you, especially on cold days or warmer days. For that reason, it’s advised to include a smart thermostat after you install a new boiler.

A smart thermostat or connecting thermostat will help control your heating system, if your hope temperature reaches high temperatures the program will automatically close your heating.

Smart thermostats ensure that your heating system is energy efficient and prevent using unnecessary energy, it reduces your energy bills and makes your place warm and cozy.

Plus, a smart thermostat program can adjust and learn the occupant pattern and heating pattern. It saves money and provides heating efficiency.

Power Flushing / chemical flushing

Power flushing was mentioned previously, engineers sometimes are obliged to power flush an old boiler before installing a new one. They conduct an extensive boiler cleansing to get rid of any remains of dust or sludges that could affect the installation process. High-pressure water is what engineers use to eliminate those foreign elements.

In rare cases, when water pressure isn’t enough to eliminate dust or sludges, engineers use another flushing method. Using chemicals to flush unwanted elements works all the time, old central heating systems and pipe systems acquire chemical flushing. Lastly, a good engineer will take approximately 2-4 hours to finish power and chemical flushing.

When must you install a new boiler?

The appropriate time to install a new boiler would be in summer when the temperature is hot and warm. It makes sense to choose that time, because and as mentioned before, some installations take longer than expected.

To install a new combi boiler, first, ask yourself why you need a new one in the first place

Here are some of the reasons and the signs that require updating or replacing your old boiler

  • Has your house heating decreased?
  • Does your boiler make noise?
  • Do you usually tend to raise your voice because of your Boiler?
  • Does your energy bill increase compared to other properties near you?
