How the TacoGenie Works: The TacoGenie is a small, silent pump attached to your hot and cold water lines in the cabinet under your most remote kitchen or bath fixture. When TacoGenie is activated, the cool water you normally let run down the drain is circulated back to the water heater through the cold water line. Instantly the pump circulates hot water from the water heater, and returns the cooled water back through the cold water line. When the hot water arrives at the faucet, the TacoGenie heat sensor and control board shut off the pump to prevent pumping excess hot water into the cold water line. Activate the TacoGenie only when you need it: TacoGenie only runs when you tell it to, and it¡¯s smart enough to know when the water currently in the line is hot enough. TacoGenie can be activated with the push of a button, or with an optional wireless remote transmitter/receiver or optional hard-wired motion sensor.
