If it does it would defy all the laws of physics.
It doesn’t. A candle contains only so many BTUs and there’s no way to increase that figure. One also needs to remember that as the temperature differential increases, the difference between the inside and outside temp, the heat transfer rate increases so that one needs more btuhs to make up the difference.
A single tea candle produces ~ 80 BTUs. 45 BTUs are needed to heat 1 square foot, so a single candle won’t even heat two square feet. A 100-square-foot room (10x10) would need 4,500 BTUs to be heated effectively, which would take over 56 candles. Tea candles cost ~15 cents each or 6 BTUs/.01$. 1 gallon of propane yields 91,451 BTU and will cost $2.304 or ~ 400 BTUs/.01$ (winter ’21 price).
