Here are 3 scenarios that determine the time you require to set up your boiler fully.

Straight boiler swap

A straight boiler swap is also called like-to-like boiler replacement. It involves switching a broken boiler with a similar type of boiler in the same location.

Time required

A like-to-like swap is the fastest type of boiler installation as the boiler goes into the same location, uses the existing pipe-work, and set up is virtually the same as the previous boiler. Usually, this takes one day. However, you may require an extra half day if:

  1. The existing pipe-work doesn’t directly align with your new boiler.
  2. Your building’s regulations require you to upgrade the gas run when replacing your boiler.

Installing a boiler similar to your existing one in a new location

If you require a new boiler fitted in a new location, or you want an existing boiler moved to a different place in your house, the process will take a little longer than a simple boiler swap. If you need to move your boiler from the kitchen to the garage or basement, for instance, the boiler installation engineer will have to:

  1. Cap off the present gas piping.
  2. Install additional gas pipe-work to the new boiler position.
  3. Adjust segments of the existing pipe-work so that all radiators can heat up properly.

Time required

You’ll need 1.5 to 2 days to fit a boiler or shift an existing boiler in a new position in your house. Either way, the time required for this kind of boiler installation increases with the distance from your current boiler.

Boiler system upgrade

Updating a boiler system is more complicated than a simple like-to-like replacement or new boiler installation. It involves changing one type of boiler for another, more suitable option. Examples of boiler system upgrades include swapping a back boiler for a combi boiler, replacing a combi boiler with a system boiler, and switching from a system boiler to a combination type.

Time required

Updating a boiler system requires more work and time than the other two types of boiler installation. This is because the boiler specialist has to:

  1. Install a boiler cylinder and revise the pipe-work when upgrading from a combination to a system boiler.
  2. Take out the boiler cylinder and re-work the gas piping and central heating structure if you’re upgrading from a system to a combi boiler.
  • Fit a condense pipe from the new boiler to a drain if it isn’t a condensing boiler.

Typically, a boiler system upgrade takes between 2.5 to 3.5 days depending on the accessibility and complexity of appliances involved.

Usually, it takes 8 hours to 4 days to fit a boiler depending on the nature of your boiler installation.
