Boiler Replacement Belfast

ODH Heating carries out gas boiler replacements across Belfast for homeowners and landlords. If your existing boiler is no longer working properly and needs replacing, our Gas Safe registered engineers will remove the old unit, fit a new boiler and test the system before leaving.

When Does a Boiler Need Replacing?

Most gas boilers have a working life of around 10 to 15 years. When a system starts to reach the end of that lifespan, repairs become more frequent and replacement parts harder to source. At that point, replacing the boiler is often more cost-effective than continuing to repair it.

Signs that replacement may be the right option include:

• The boiler is over 12 years old
• Faults are recurring despite previous repairs
• Heating bills have increased without a clear reason
• The system struggles to heat the property adequately
• Parts are no longer readily available
• The boiler is making persistent unusual noises

If you are unsure whether repair or replacement is the right call, our engineers will assess the system and give you an honest recommendation. You can also read more about boiler repair in Belfast if you are weighing up your options.

Types of Boiler We Install

There are three main types of gas boiler and the right choice depends on the size and layout of your property and your existing heating setup.

A combi boiler provides both heating and hot water from one unit without a separate cylinder. Generally suited to smaller properties and single-bathroom homes.

A system boiler works with a hot water cylinder and is better suited to larger homes or where hot water is needed in more than one place simultaneously.

A regular boiler (also called a conventional or heat-only boiler) works with both a cylinder and a cold water tank, typically found in older properties with a traditional system.

Our engineers will advise on the most suitable type for your property before any work is agreed.

What the Replacement Process Involves

On the day of replacement our engineers will isolate the gas and water supply, remove and safely dispose of the old unit and fit the new boiler in the same location or a new position if required. The flue, pipework and controls are connected and the system is filled, pressurised and tested. Before leaving we will walk you through the controls and make sure you are comfortable operating the new system.

Gas Safe Certified Installation

All replacement work is carried out by Gas Safe registered engineers. On completion a certificate is issued confirming the installation has been carried out to the required standard. This is important for your records — particularly for landlords and anyone planning to sell the property.
