What’s the Best Boiler for a Belfast Home in 2025?

What’s the Best Boiler for a Belfast Home

Choosing the right boiler for your home in Belfast isn’t a one-size-fits-all decision. With rising energy costs, changing home layouts, and advancements in boiler technology, it’s more important than ever to pick a system that suits your needs and saves you money.

In this guide, we’ll break down the three main types of boilers — combi, system, and regular (conventional) – and help you decide which is the best fit for your home in 2025.

The 3 Main Types of Boilers Explained

Combi Boilers (Combination Boilers)

Best for: Small to medium homes with one bathroom
How it works: Heats water directly from the mains when you turn on a tap – no storage tank needed.

Pros:
Compact and space-saving
Hot water on demand
Lower installation costs
Highly efficient

Cons:
Struggles to supply multiple showers/taps at once
Not ideal for homes with low water pressure or more than one bathroom

Ideal for:
Terraced houses, apartments, and smaller semis in areas like the Lisburn Road, Holywood Arches, or Ormeau.

System Boilers

Best for: Medium to large homes with multiple bathrooms
How it works: Uses a separate hot water cylinder (but no cold water tank). Still connects to mains water.

Pros:
Great for homes with high hot water demand
More efficient than regular boilers
No need for attic tanks

Cons:
Requires space for the cylinder
Not as instant as combi boilers for hot water

Ideal for:
Modern homes or renovated properties in areas like Dundonald, Four Winds, or Newtownbreda where space isn’t an issue and families use more than one bathroom.

Regular (Conventional) Boilers

Best for: Older homes with existing traditional heating systems
How it works: Requires both a hot water cylinder and a cold water tank in the loft.

Pros:
Works well with older pipework/radiators
Handles multiple hot water demands at once

Cons:
Takes up the most space
Slower hot water recovery
Higher installation and maintenance costs

Ideal for:
Larger period homes in areas like South Belfast, Malone, or North Belfast, especially if you want to keep your existing heating setup.

Other Things to Consider in 2025

Smart Controls Compatibility: All modern boilers can now be paired with smart thermostats like Hive or Nest.
Energy Efficiency Ratings: Look for ErP A-rated models to keep your bills low.
Gas vs Oil: If you’re still using oil, this might be a good time to consider a switch to gas

Our Recommendation

If you live in a modern 2-3 bedroom Belfast home with 1 bathroom, a combi boiler is likely your best bet.
For larger homes with multiple bathrooms, we usually recommend a system boiler — especially if you want strong water pressure throughout.
