If your water heater suddenly and accidentally tears apart, cracks, burns or bulges, any resulting damage to your personal property is covered. If water drips or seeps from your heater over a period of time and gradually ruins your carpeting or flooring, this “slow loss” is not covered. If you notice dampness around a water heater, you'll save money by calling the plumber before serious damage occurs. Damage to your water heater itself is not covered, unless the damage results from fire or another type of covered loss listed here. Damage from freezing of your water heater is not covered.

The fixture that provides heated water to the hot-water system of a house or building. Water heaters are usually heated by gas, oil or electricity. Gas and oil heaters tend to be cheaper, but need ventilation. Water heaters are usually separate from the boiler system that heats some buildings, although some buildings do use the boiler as a source for hot water. The water heater typically consists of a tank that receives cold water, heats it and stores it until it needs to be delivered through the hot-water system. Most single-family homes require a 40- to 60-gallon tank.

Vessel in which water is heated and is withdrawn for use external to the system.
