Wanting to cut costs on the energy bill, especially now that temperatures are dropping for the season? Economics may be one reason to seek more sustainable energy sources, but this inventive way to heat the house is also purely fascinating.
Journalist, YouTuber, and boat owner Dylan Winter created his DIY heater using tea lights and placed inside a bread tin and covered with two ceramic flowerpots.
This creative system uses the scientific principles of convection heat transfer and, according to Winter, can heat his home for around 8 hours a day.
His YouTube Channel KeepTurningLeft shows how the method works: The tea lights are first put into a bread loaf tin and covered with a small upside-down flower pot.
The hole in the top of the upside-down pot is covered with the metal casing leftover from one of the tea lights. Then the pot is covered by a second, larger pot and the hole in the bigger flower pot is left uncovered.
This system works because the candles produce gases full of heated particles that are captured and channeled through the pots. As hot gas particles are lighter than the air, they will rise up through the top into the colder area.
What will then be caused is the cold air to fall into the warm areas and create a convection current; then heat is transferred from one pot to another, and then out of the hole.
One does not need a huge amount of money to invest in this economical heating method, either. Winter began by buying 100 tea lights from Ikea for less than a dollar, a standard loaf tin, and two different sized flower pots. In the video it is shown four candles are used for the heating system.
