The Ugly TRUTH About Cast Iron Boilers

Cast iron is basically steel with a high level of carbon impurities… and carbon doesn't translate into longer boiler life.; Cast iron is a brittle material which can fracture under temperature shock. It's well known that it is common for today's cast iron boilers to have cracked sections, cracked burner doors, leaking gaskets, and leaking tankless coil flange.
