Why should you get a new boiler?

There are a few factors that boiler specialists suggest are signs that you should replace your boiler with a new, highly efficient one. These are:

Age: If you have had your boiler for over 15 years, you might be due for an upgrade.

Rising energy bills: If you notice that you are no longer saving on your energy bills, it means that your appliance is losing its efficiency and might need to be replaced.

Frequent repairs: If your boiler regularly acts up and requires repairs, you will want to think of replacing it with a new one. This way, you avoid overspending on frequently fixing a faulty boiler.

Strange smells: In the event that you notice odours coming from your boiler, you should act immediately, as it might be a sign of a combustion problem or a gas leak.

Issues with heating: When it takes too long for your home to warm up or if you notice signs of inconsistent heating, you should have your boiler checked and potentially replaced.

What does the boiler replacement process look like?

There are a few steps involved in the process of fitting a new boiler in your home. Below is a rundown of the different steps you can expect as part of the boiler replacement procedure:

  1. Choosing the right boiler: Find an appliance that meets your energy consumption requirements.
  2. Removing the old boiler: At this stage, an engineer will turn off the gas supply and disconnect all the pipework in place.
  3. Preparing the installation site: This step might require measures such as removing or altering pipework or installing a new flue.
  4. Installing the new boiler: The new boiler you chose will be installed and connected to the existing pipework and heating system.
  5. Testing the new boiler: To make sure that your new boiler is operating properly, the engineer will conduct a series of safety checks after the installation.
  6. Commissioning the new boiler: The engineer will set up your new boiler to maximise performance and efficiency.

How long does it take to replace a boiler?

Replacing a boiler typically takes anywhere between 4 hours and 4 days. The exact estimate depends on the boiler type, its accessibility, the complexity of installation, and any necessary piping or plumbing work.

Here’s a quick breakdown:

  • Simple installation (4-6 hours): swapping a like-for-like model in the same location.
  • Complex installation (1-4 days): installing a new boiler type, relocating a boiler, switching to another fuel type.

Consult a qualified heating engineer for a more accurate estimate.
