People decide to replace their boilers for a variety of different reasons, and there are a variety of models to choose from.
Whether your current boiler has broken, or you are looking to upgrade your system, it’s important to know which model will work best for you.
You may be deciding between a combi boiler or system boiler, but which one is best?
Combi boiler
A combi boiler or ‘combination boiler’ is popular in the UK, with many homes having this type of boiler installed.
They are smaller than a conventional boiler and can fit in a more compact space. This type of boiler works by using a combination of a tap water heater and a central heating system that is all together in one unit.
A combi boiler heats water instantly via the mains, so there is no waiting time and no need for water tanks.
Benefits
- Combi boilers are energy efficient as they use modern systems.
- They are great for smaller homes, as they take up less space.
- They are better for the environment, as you use less water as it is heated instantly.
- There is less pipework in your home, so repairs are less invasive if it breaks.
- These boilers are generally less expensive to repair if there is a problem, as there is less pipework.
- There’s no waiting around for a tank to refill.
- Most new-build homes will have this type of boiler installed.

System boiler
Although a combi boiler is a great option for many people, a system boiler may be more appropriate for you.
This boiler system takes water directly from the water supply and heated up using gas or electricity, it is then stored in a hot water tank until it is needed in the home.
This hot water is also used in radiators to provide heat for the central heating system, and can be reused multiple times.
They are built with the expansion vessel and pump built in, meaning they are easy to maintain and install. They are most suited to larger homes with more than one bathroom.
Benefits
- If your home has an airing cupboard or loft space, this can be the ideal place for the hot water tank.
- These boilers are compatible with solar water heating systems, increasing the money you can save on household bills.
- Great for a household that uses a lot of hot water at the same time.
- You can store clothes or towels in the cupboard where the water tank is, to keep them dry.
