What are the benefits of a combi boiler?

Combi boilers are very popular due to how useful they are to many types of households. Benefits of combi boilers include:
-Saving space: combi boilers combine the central heating boiler with the water heater, which reduces the amount of space required. This means combi boilers are more space effective, allowing you to use the extra space as you wish.
-Lower costs: Due to the boilers being combined, they are easier to install, which can lead to lower installation costs than system and conventional boilers.
-Instant water: Combi boilers use the water mains grid to retrieve water to use in your heating system, meaning your showers will be more powerful.
-Efficiency: Combi boilers are considered to be highly efficient, with many combi boilers having an efficiency rating of over 90%.

What are the disadvantages of a combi boiler?

Combi boilers, despite being used in most UK households, do have one major drawback: they are not ideal for larger households. If your household has several bathrooms, or lots of rooms, then a combi boiler will not be powerful enough to supply the entire house. A system or conventional boiler will be more efficient for larger houses due to their use of a water cylinder.

The other main drawback to combi boilers is their usage of the mains. This may be beneficial from a space perspective, however, this can significantly impact the pressure of the water if multiple water appliances are being used at the same time.
