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.

What is the correct temp setting for a hot water boiler

Per my earlier post about a gravity hot water conversion to a sealed circulated system. I have another question about the correct temperature setting for boiler itself. I have read that around 180 degrees may be a typical setting for the boiler control, but during my investigations into this system, I noticed that they had it set at 200 degrees.
