During winter, we keep our room warm for our cozy. No doubt, the more electricity you spend to keep your room warm, the more bill you get at the end of the month. But a YouTube user as well as journalist and boat owner named Dylan Winter has devised a way of heating a room just by spending 8p per day using tea-lights and & flowerpots.
Dylan Winter (YouTube username KeepTurningLeft) has created a DIY heater using tealights placed inside a bread tin and covered with two different-sized ceramic flowerpots. It costed him £1. He placed the smaller flowerpot upside down and covered the center of the bread tin. Be noted, Winter placed 4 burning candles inside the tin too. On the other side, he placed the larger pot upside down over the smaller pot, and the hole was left uncovered.
Following the scientific principles of convection heat transfer, the heat from the candles warms the inside of the smaller flowerpot, and the ‘inner core’ becomes ‘very hot.’ Then a ‘convection of air’ is created between the smaller and larger pots and this heated air comes out the top of the homemade heater. As the heated air (actually hot gas particle) is are lighter than the gases in the air, it rises up into the colder area.
It is to be noted that each tealight burns for around 4 hours. Dylan Winter used 4 tealights in the morning and 4 in the afternoon to heat his rooms for 8 hours a day. However, now the question is how to build such heater, right? No worries, here’s a video explaining how to build the heater.
