The KitchenAid instant hot water dispensers work by heating water from the cold water supply line and saving it in a reservoir. This reservoir maintains the temperature of the hot water until it is needed.
Instant hot water dispensers have a built-in heating element. When water is brought in from the cold water supply, this element activates. It remains on until the water has reached the needed temperature. The specially designed reservoir ensures that the water remains at the desired temperature until it is called upon. This process is similar to the operation of hot water heaters.
In order for the instant hot water dispenser to work, the device must be connected to an electrical line. KitchenAid models accomplish this by connecting the device to a standard electrical outlet. This electric current allows the heating element to reach the desired temperature. If the device stops producing hot water, the power source may be the cause. Resolving this problem involves checking the plug and breaker.
The hot water reservoir is a limited resource. As a result, using a lot of instant hot water may cause the supply to be diminished. The device should refill in 15 to 20 minutes. As a result, projects which require a large amount of hot water are not easily accomplished using the instant hot water dispenser.
