I believe they used an acid or some type of cleaner that clears the mineral deposits inside the coil. They basically choke down like a cholesterol choked coronary artery which chokes off the flow of water and the build up prevents heat transfer too. Water treatment helps the problem tremendously, but I have never been a fan of them, the coils.
