Water-heater tank is a device producing sanitary hot water for washing and bathing; it consumes gas Water-heater Tank or electricity Water-heater Tank. Take a look on its operating system and plumbing sytem.
high-temperature cutoff
Mechanism cutting off the flow of electric current when the temperature of the water exceeds a set value.
overflow pipe
Pipe through which water escapes when maximum pressure is exceeded.
pressure relief valve
Device for lowering the pressure inside the tank by releasing excess hot water.
drain valve
Device for emptying water from the tank. stem faucet
electric supply
Point where the hot-water tank connects with the household circuit.
access panel
upper thermostat
Device that senses changes in temperature and automatically switches the upper heating element on or off.
hot-water outlet
Outlet pipe for hot water flowing into the hot-water circuit.
plumbing system
cold-water supply
Inlet pipe for cold water to the tank.
insulation
Material placed between the tank and the outer walls of the hot-water tank in order to reduce heat loss.
tank
Insulated reservoir in which hot water is stored; it is usually cylindrical and enameled or glazed.
lower heating element
Coated electric resistor immersed in the lower part of the tank to heat the water.
lower thermostat
Device that senses changes in temperature and automatically switches the lower heating element on or off.
upper heating element
Coated electric resistor immersed in the upper part of the tank to heat the water.
anode rod
Magnesium-coated electrode protecting the tank from the corrosive effects of the water.
