Blue Flame Propane: What Color is Propane?

You may appreciate the warmth and efficiency of propane, but did you know it’s also green?
Propane is an approved alternative fuel in both the Clean Air Act of 1990 and the National Energy Policy Act of 1992. It is nontoxic and insoluble in water. Because it is used as a gas, it does not spill, pool, or leave a residue. It’s a safe fuel to store underground, as it will not contaminate groundwater, even in the unlikely event of a leak.

Also, its carbon footprint, a measure of its impact on the environment, is much less than other fuels. A gallon of propane burned produces about half the carbon dioxide (CO2) as a gallon of fuel oil. Compared per Btu of fuel, propane releases less CO2 than ethanol, gasoline, bio-diesel, kerosene, or coal.

In traditional tank water heating, electric heaters produce 150 times the greenhouse gas emissions of a propane heater. A tankless propane water heater can even further reduce emissions.
