 Things You Should Know Before Installing a Boiler

AN A-Z GUIDE ON BOILER INSTALLATION. Installing a new boiler is considered a big task and is often stressful. We are aware of this fact that is why we have put together this guide to help you know what it takes to complete a boiler installation in London and help you prepare adequately for it.

With this article, you will know what to consider before getting a new boiler, what happens during installation, and what to expect after your boiler is installed. However, it is important to know some basic facts about a boiler before you embark on your this journey.

Types of Boilers

There are three main types of boilers. They include:

  • Conventional
  • System
  • Combi

To get the right one for your home, this will depend on the gas connection, how much hot water you need, the space available for a boiler, and how efficient you want the boiler to be. If you’re replacing your boiler with a new one of the same type, it makes the process easier but changing to a completely different type may be difficult. However, if the change is to a more energy-efficient type, the benefits will outweigh any difficulty in installation.

What Size of Boiler is Suitable for Me?

Your gas engineer will advise you on the size of the boiler that will be suitable for you. We consider the following to help our customers choose the right size of the boiler.

  • The amount of water you use

A large family home will always use more water compared to a one-bedroom apartment with a single occupant. Generally, conventional boilers hold more hot water and are best suited for homes with high water usage while combi boilers are better for homes with low water usage.

  • The space available for a boiler

Combi boilers do not require water cylinders, so they take up little space. This makes them a preferred option when your boiler space is limited.

  • The position of the boiler

Having a new boiler installed in the same place that an old one was fitted reduces the stress of installation and causes minimal disruption. Most times, people install their boilers in their kitchen or cupboard, but it can be installed in any room if it has good pipework and the flue is in the correct position.

Getting a Professional Boiler Installer

You need to be home during the installation for your engineer to show you how to operate the new boiler controls.

It also depends if the change is a basic like-for-like switch to a new model or a complete system change with additional features like power flushes.
