Chillipeper The Chili Pepper saves the water that normally runs down the drain while you are waiting for the water to get hot, saving thousands of liters of water per year.

The Chili Pepper pumps hot water from your water heater to the tap. The initial cool water is circulated back to the cold water inlet of your hot water service. When the water at your tap is at the desired temperature, the Chili Pepper switches off - turn the hot tap and you get nothing but hot water.

Retails for around $470. Find out more at Neco.
