How Long Does Large Coal Boiler Use

The Average Boiler Life Expectancy DoItYourself.com

The average expectancy of a traditional gas boiler is between 10 and 15 years, if you keep it well maintained and have it serviced annually. Other boilers, such as electrical devices, will last between 8 and 10 years. A superior quality boiler, that is the most expensive available, can be maintained so that it lasts for 20 years or more.
