If there is a absolutely old brownstone factory or ware apartment in your town, it’s almost a guarantee that its heated by a cast iron boiler, then these old Heating as well as Air Conditioning units were the tied in addition to true familiar for nearly a century, but the time has come to put them into retirement, then while boilers are awesome, not all boilers are created equal. Cast iron boilers tend to still be found in these older buildings because know it or not, they still work, but just because they’re still running doesn’t mean they’re running well, then much like the old golden Toyota Corolla that you’ll often see on the road from 1996 with over several hundred thousand miles on it, barely absolutely working is easily bizarre from absolutely working charmingly. The problem with cast iron is they’re made from a easily brittle material, which means it sustains disfigure instead of flexing in addition to moving with temperature changes. This is how old cast iron boilers often get cracks that cause problems with the overall effectiveness of their gas furnace! Even though a cast iron boiler can last up to 60 years or more, in that time it will not at all be running as well as the day it was first installed. That’s why steel boilers are so popular today, then steel flexes, unlike cast iron, so it doesn’t crack under pressure. They also have a much higher SEER rating in addition to are more effective at stopping heat loss. Certain models of steel boilers have even been told to last at least 35 years, if not more! Unlike its cast iron cousin, the steel boiler will run just as perfectly as the day your had it installed with official professional heating in addition to A/C care.
