Domestic hot water storage heaters sometimes fail to operate efficiently due to corrosion and/or scaling of the tube bundle. An investigation was conducted to determine the nature, severity, and cost of this problem at several locations throughout the United States. The use of a baked-on phenolic coating to mitigate corrosion and scaling problems in domestic hot water storage heaters was investigated and tested in the field. A cost analysis comparing the coating to other methods of scale and corrosion mitigation was performed.
