Which is the best boiler to buy in 2024?

Combi boilers
These heat water straight from the mains, giving you hot water on demand. This means that they're ideal for small to medium homes as you don’t need a hot water cylinder or cold water storage tank, saving you space. 

Regular boilers
Good for houses with more than one bathroom, as they provide hot water to multiple taps at the same time. These types of boilers do require more space as they work with a hot water tank and cold water storage tank, but they're a good solution if you have low water pressure.

System boilers
Much like regular boilers, these are ideal for multiple bathroom homes, due to the hot water tank. However, they take up less space than a regular boiler as a cold water tank isn't needed.

Normally, homeowners just want an upgrade of the boiler type they have now, however, you should consider other types if your heating needs have changed. For example, you may have added more bathrooms to your home or may want to get rid of storage tanks to free up space (e.g. for a loft conversion), meaning a different type of boiler may now be a more suitable replacement boiler. You’ll also need to consider which size of boiler is best for you, to make sure it suits your needs.
