A heating source that costs 4 cents per hour? In other words, just under one dollar a day? That sounds good. Almost too good. Wait, is it too good to be true? We did a bit of research to see what people’s experiences with using these homemade flower pot heaters was, and just what kind of results you get for 4 cents an hour.
First off, lets look at what it costs to heat a house the regular way. For winter climates, it can be a hundred dollars a day even, and for people who don’t need much heat they might be spending just a bit more than 4 cents anyway, like some people who looked into these heaters.
One thing that a lot of people found and that’s worth sharing is that these pots don’t make more heat than a regular candle. They work through thermodynamics in the regular physics world like any other flame. Flame, by the way, is something to be cautious about. These units can be fire hazards. What the pot does, however, is store the heat and release it more slowly in a room.
Most of the images will provide heat you can notice in a tent or something, but if you want to heat – really heat – a larger room, they probalby won’t be effective enough.
However, they can be fun to make and if you’re in a space that’s not too big, and that isn’t affected by a fire hazard, these things might be worth making.
One thing to note for those who are going to make them: You need air flow underneigth the pot, and if you’re using multiple pots, you can separate them by something like metal washers.
Overall thoughts. Not a worthless invention, and might be fun to use, and practical if you have these materials around, but not the most efficient source of heat possible.
