If it hasn’t been updated, find out when the home was built. If the heating system was installed after the home was built, find out the installation date. This is all very important information for your project.
It is best to have the heating system, specifically the hot water tank, updated somewhere around every 10 years. Hot water tanks can burst if they get too old or break, which can leave you with a flooded mess of a house depending on where it is located. If it is in the basement and part of the basement is finished, you will have to replace a lot of carpet and drywall.
