Tiny Device Claims to Heat Your Room for 10 Cents a Day

Egloo is a clever little terracotta heater that harnesses the power of tealights to heat spaces up to 20 square feet for as little as 10 cents a day, without using any electricity.

Developed by Marco Zagaria, a student at the Academy of Fine Arts in Rome, Egloo is both cheap to use and eco-friendly. Made up of two small terracotta domes and a metal tray, the device takes advantage of the natural heating ability of these materials, drawing heat from just four tealights placed inside it and releasing it in your living space. As the candles burn inside, the distinct dome shape of the innovative heater allows it to gradually heat up and radiate the heat, while the small hole on top keeps combustion going and and also releases some of the heat, allowing it to spread throughout the room.

“Egloo is conceived for contrasting continuous waste of electricity used for warming domestic rooms, offering, as an option, a candle-powered way that provides a cheaper and more ecological energy,” the product’s website states. “It takes advantage of features of terracotta that stores the heat and slowly and gradually releases it by radiation, even after it blows out.”
