The Average Boiler Life Expectancy
Appliances for your home are a big investment. Knowing how long they will last you, will allow you to budget accordingly. Here is what you can expect for your boiler.
Basics
Boiler life expectancy depends very much upon the type of boiler that you purchased. 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. Although, the chances are that you will have moved to a new house, or need a more energy efficient boiler, before it needs replacing.
Factors That Reduce Life Expectancy
Corrosion can help to reduce the life expectancy of your boiler. Corrosive elements which attack the equipment can significantly reduce the ability of your boiler to function effectively, and will make it more prone to break down, and eventually require complete replacement of your heating system.
Adding water chemicals to your system can help to keep the corrosion down, and boiler blowdown will make sure that silting and other solids produced by the chemicals are released harmlessly. Excessive pressure can also cause wear-and-tear on your boiler, and you may find that over use of the boiler will also damage the hot water system to the point where it cannot be repaired.
Like most things, the life expectancy of you broiler is no different. You get what you pay for.
