An invention that allows you to heat your home in an ecological way

The effectiveness of four candles burning for around five hours to heat a 20-square-meter room can raise questions about its effectiveness. However, this is demonstrated by Egloo, the invention of Marco Zagaria - a student at the Academy of Fine Arts in Rome - who designed a small intelligent heater that takes advantage of the energy of a candle to heat an environment without wasting electricity.

Egloo works by concentrating the heat of the candles inside a terracotta dome, a material particularly suitable for heat, stored quickly, is slowly and gradually transported to the environment by thermal radiation.

This original heater is made up of four elements: the base, the grill and the two domes. The base offers a space to place the candles that, once lit, will heat the domes. The metal grill, placed at the base, serves as a support for the domes.

The thinner dome, placed in the center of the base, stores a high rate of heat, which is transmitted to the outer dome; the upper air intake facilitates the exit of hot air stored between the covers, which allows heat exchange.

For Egloo to function properly, only three candles are needed. With an average duration of five hours, they are enough to heat a 20 m2 room. Once turned on, it takes five minutes to reach the proper temperature and in about 30 minutes it will increase the room temperature by 2-3 degrees. Another fact to keep in mind that it allows heat to radiate into a room even after the candles have gone out.

The first step in the Zagaria design process was to work through sketches, to achieve the best model, in terms of aesthetics. In the second stage based on modeling, the study of shapes and volumes was refined to achieve the most accurate model, ready for prototyping. In the third stage, several handcrafted physical prototypes were made to test and improve the characteristics. After evaluating the appropriate changes and further refining the model, the matrix was made through 3D printing.

Egloo has a simple and compact shape which allows it to fit anywhere. It weighs 1 kg and is available in several versions: natural, colored and enameled. Its price is from 45 euros ($ 750) and they send it to Argentina and the rest of the world through
