How Efficient Is Your Fireplace Fuel?

Overview

Objectives/Goals For my science project I wanted to determine which fireplace fuels work most efficiantly to heat a room for the least amount of time, energy, and money. Methods/Materials For my experiment I used three fuels: nautral gas, presto logs, and firewood. I then weighed each fuel and I burned them individually in a pie tin underneath a coffee can which sat on a metal grate. Inside the can was one cup of room temperature water. Next, I timed how long it took each fuel to boil the water to 100 degrees celcius. Finally, I smothered the fuels and weighed them again to see how much grams of fuel it took to boil the water. Results From my experiment it turned out natural gas was the most efficient, followed by presto logs, and then firewood. Yet firewood was the cheapest, followed by presto logs, and natural gas which was the most expensive. Conclusions/Discussion It turned out that natural gas was the most efficient fuel because it has the most complete combustion out of all three fuels, and has no leftover residues so it burns pure. I also discoverd that the more efficient a fuel got, the more expensive it became.
