Q: What kind of fuel does your boiler use?
All the brands mentioned in this article offer energy-efficient combi boilers. However, Viessmann, Vaillant, and Worcester Bosch are often recognized for their particularly high energy efficiency.
The average lifespan of a combi boiler is between 10 to 15 years. However, with regular maintenance and servicing, some boilers can last up to 20 years.
It is recommended to service your combi boiler annually to maintain its efficiency, safety, and reliability.
Combi boilers are ideal for small to medium-sized homes. For larger homes with multiple bathrooms, a system boiler with a hot water cylinder might be a more suitable option to ensure consistent hot water supply.
No, you should always hire a Gas Safe registered engineer to install, maintain, or repair a combi boiler. DIY installation can be dangerous and will likely void your warranty.
