The Average Boiler Life Expectancy. Boiler life expectancy depends very much upon the type of boiler that you purchased. The average expectancy of a traditional gas boiler would be 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.
The average life span of a gas furnace is approximately 15 years, compared to 20 to 30 years for an electric furnace....he average gas furnace will last about 20 years before needing to be replaced. If yours is over 15 years old consider having it replaced earlier than that.
