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.
When you see how much more efficient gas furnaces are compared to oil furnaces, itâs easy to see why gas is such a popular option. However, all of that energy efficiency comes at a price! The average gas furnace with a 90% AFUE (thatâs the rating that determines just how energy-efficient your furnace is) will cost you about $2,500 (and, of course, that doesnât include installation costs. Count on spending about $2,000 to have your new furnace installed). If you opt for a multi-stage gas furnace, youâll get even more energy efficiency, but youâll also wind up spending hundreds of dollars more on it! Compare that to the average oil furnace â which will cost you about $2,000.
