What happens if your water heater is too hot?

In terms of your hot water heater, hard water in your home plumbing will lead to calcium build-up on the inside of the tank. This, in turn, will interfere with your appliance’s ability to effectively heat the water and control the temperature, resulting in H2O that is suddenly too hot or too cold.
