### Boiler Safety - Occupational Safety and Health Administration

Areas with moderate-high limescale are the most likely to get problems with limescale build-up in boilers. When limescale builds-up on your heat exchanger, it creates a hot spot. A certain part of the heat exchanger is going to burn hotter than the rest. And, the part that is burning hotter, is going to be put under immense pressure.
