How to Determine the Age & Life Expectancy of Heating Boilers & Furnaces InspectAPedia®  -     Here are Data Decoding Documents that Determining Boiler, Furnace, or Heat Pump Age How long should a boiler, furnace, or heat pump last? What factors determine the life of heating equipment?

This article provides documents that explain and translate all of the data found on information tags and stickers used on heating & heat pump equipment, including equipment age, heating capacity, electrical requirements, and operating characteristics.

Readers who need to determine the age of other mechanical equipment in buildings should also see AGE of AIR CONDITIONERS & HEAT PUMPS and for water heaters, see AGE of WATER HEATERS.This website answers most questions about all types of heating systems and gives important inspection, safety, and repair advice. If you don't know what kind of heat your building uses, see our introduction at BOILERS, HEATING. If your heating system is not working properly, see NO HEAT - BOILER / FURNACE DIAGNOSIS.
