What makes a perculator heat? - Faberware 12-55 Cup Coffee Urn

Hi, If you have a Farberware, Just look into the bottom of the pot. There you will see what looks like a hole in the pot. That is the high heating element, under the pot, when you go to make coffee the pump ( rod) sits into the hole. When you turn it on to make coffee the high heating element that the pump is in gets very hot and starts pushing the water that is in the hole to the top (that is called perking) the hot water goes over the the top and the drops into the coffee, This keeps going on until the thermostat feels it has reached 190 degrees or close to it and turns the high element off. While this is running it's cycle the keep warn is on helping the water to get hot, when the main element is off the keep warm element that runs around the bottom of the pot stays on all the time the pot is plugged in. Should the coffee get to cold the thermostat will turn the main heating element back on until it is back to 190. This system was developed by Farberware and a lot of makers copied it, But Farberware sold the pots and was known for a FAST and HOT cup of coffee. Farberware started making them in China and the pots are having a hard time keeping it up to American standers, and parts are very scarce.Farberware USA pots have been around a long,long time and are still going strong . I hope this helped you to understand how the pot works.
