Egloo | Domed Candles

Egloo | 5 tea lights can heat a room for just 25 cents.

Not at all dissimilar to igloos in name, form or function, Egloo is a terracotta device designed by Marco Zagaria that is intended to warm a room on a budget. The hemispherical curiosity houses small candles, and through a cleverly channelled air flow and terracotta heat-stores, gives off a remarkable amount of heat over a period of time.

Egloo is made up of two terracotta domes, as well as a terracotta base and a metal stand. Four tealight candles are lit inside the device, and they heat up the internal terracotta dome that is placed above  them. Terracotta is favoured for its heat-storing properties and this closed dome holds the heat of the candles to releases it slowly.Air is then drawn in through the sides of Egloo, flows over this inner dome, and shoots out the hole in the top of the outer dome due to warm air’s tendency to rise. This animation gives a better overview of how Egloo is composed.

Using Egloo is a remarkably cheap way to heat a room due to the low price of tealight candles. The team forecast that a 20m² room can be heated by 2° to 3° for up to 5 hours at a cost of just 10 cents!

Smart use of materials means that 5 tea lights can heat a room for just 25 cents.
