A boiler is the lifeline of any heating system. If you feel like things are going down with your old boiler, you should be aware of the fact boiler installation requires your full attention and, admittedly, a considerable sum of money. Once you experience a complete boiler breakdown, you won’t have another choice but to replace it with a new heating buddy. Today, we are here to point at some of the factors determining the installation process.

Types of Boilers

When considering replacement options, you should know what types of boilers are there. Different types of systems include:

Combi boilers

  • Compact,
  • Cheap installation,
  • Supplies you with a constant flow of hot water,
  • Doesn’t require loft space,
  • Ideal for smaller properties.

System boilers

  • Good choice for properties with two or more bathrooms,
  • No loft tank,
  • Highly efficient,
  • It provides a constant hot water supply to all taps in your home.

Conventional boilers

  • Best choice for large households where there is a constant need for hot water,
  • Suitable for properties with more than one bathroom,
  • A cold water storage tank and hot water tank required.

How to Know It Is About Time to Get a New Boiler

The first factor to consider here is the age of your boiler. If you have been using the same boiler for 10 to 15 years now, no doubt you need a replacement. The top boiler manufacturers in the UK advise not to wait until the very end of the lifecycle of your boiler but to replace it as soon as some of the following conditions are met:

  • Your current system fails to meet your heating and hot-water needs,
  • You have a low energy-efficiency rating boiler, which results in high energy bills.
  • You are not content with the current location of your boiler,
  • You have plans on selling the property. (A new, fitted boiler appears more appealing to tenants/buyers, mostly because they are aware of the energy-efficiency of new boilers.)

Things to Consider Before Making a Purchase

Boiler installation is, in general, expensive and demanding task, which is why you would want to take some of the following features into account before making a purchase:

  1. A kW output

When buying a new boiler, it is essential to consider your property’s hot water and heating needs. Rely on the number of bathrooms and radiators in your household. The higher your water and central heating demand is, the higher the kW output you need. For instance:

A household with 1 bathroom and 10 radiators maximum would use 24-27kW boiler,

A household with two bathrooms and 15 radiators would benefit most of the 28-34kW boiler,

A household with more than two bathrooms and 20 radiators or more requires a 35-42 kW boiler.

  1. Energy and efficiency

The top boiler manufacturers in the UK are making energy-efficient boilers, enabling them to save up some money and reduce their energy waste. If your monthly bills are draining your wallet, think about replacing it.

  1. Reliability

If you experienced a boiler breakdown lately, you already know how expensive this repair was. When making a purchase, you want to think long-term. In other words – you need a reliable boiler that won’t break the bank either.

  1. The location of your new boiler will be installed at

You want a boiler that fits your spacing and household appearance. Most of the times, it is more economical to install it in the same place as your old one. Yet, if you care about the appearance more, you can choose from a number of other locations in your household.

The Boiler Installation Process

Having a new boiler installed means you would have to hire a gas engineer. Safety always comes first, and you want a certified person to perform the installation. Here is what to expect:

  • A gas engineer you hired will double-check the essentials – the number of bathrooms, water pressure in your household, number of radiators, and the current location of your old boiler.
  • The straightforward installation is an easy task for an experienced engineer. If you are replacing your old combi with a new one, you can expect the installation to be done in a day. However, replacing your old boiler with another type or changing its location may take up to 5 days.
  • The gas engineer you hired should notify the local authorities about installing a new gas appliance in your home. Afterward, you will receive a Building Regulations and Benchmark Certificates.

How Much Does the Boiler Installation Cost?

In a nutshell – a typical replacement will get ₤1500 to ₤3000 out of your pocket. For this reason, make sure to buy a boiler with a warranty from a trustworthy supplier.
