A heat exchanger is a core component in boilers that transfers heat from combustion gases to water or air. It is typically made of materials like stainless steel or copper for efficient heat transfer and durability. Over time, heat exchangers can suffer from corrosion or cracking, leading to leaks or reduced efficiency. Replacing a faulty heat exchanger is a major repair that restores heating performance and safety. Ensure compatibility with your boiler model.
