Get more energy bang for your buck with propane!

propane flames clinton, me If you’re new to having propane in your Central Maine home, you may think it’s the same thing as natural gas. After all, they’re both gases, right?

Nothing could be further from the truth! Propane offers benefits that natural gas cannot match. One of those advantages is energy efficiency.

Propane burns at a temperature of 3,560˚ Fahrenheit, the same as natural gas. However, the resulting combustion products are distinct from each other.
Propane surpasses natural gas in energy efficiency. While one cubic foot of natural gas produces approximately 1,012 Btus (British Thermal Units) of heat, propane outshines it with an impressive 2,520 Btus per cubic foot!

A single BTU represents the energy required to raise the temperature of one pound of water by 1˚ Fahrenheit.

To accomplish various tasks such as heating your home, heating water, cooking, and using other gas appliances, a larger quantity of natural gas is required compared to propane. Here’s an illustration: In a span of one hour, a 100,000 Btu natural gas furnace will consume approximately 97 cubic feet, whereas a propane furnace will only consume 40 cubic feet within the same time frame.

Indeed, natural gas not only lacks heating power, but it also requires a larger quantity to deliver subpar results. Who would willingly opt for such an undesirable choice?

What color should a propane flame be?

Achieving a balanced air-to-fuel ratio ensures ample oxygen for thorough combustion. As the gas molecules in the flame become ionized, a vibrant blue color emerges. The presence of a blue flame signifies complete combustion, guaranteeing safe and efficient burning of propane at maximum heat, while minimizing wastage.
If you observe orange or yellow flames on your propane burner, it signifies inefficient burning of gas. This problem often occurs on a propane range when spilled food and debris obstruct the burner. By ensuring regular cleaning and maintenance, you can uphold peak performance and prevent the occurrence of such discolored flames.

Improper combustion can result in propane wastage, ultimately increasing your energy expenses. In complete combustion with a blue flame, the temperature of a propane flame is 3,560˚ Fahrenheit. With a yellow or orange flame, the flame’s temperature is 1,832˚ Fahrenheit.

Cooking with only half the heat generated by an oven’s heating element can significantly impact the quality of your dishes. It can lead to uneven temperature distribution in your pan, preventing you from achieving that desirable browning or searing effect. Moreover, quick-cooking foods like stir-fry may not turn out as well. Additionally, the presence of orange or yellow flames can lead to inefficiencies in your home’s heating and water heating system, ultimately resulting in higher energy bills.

Flames that exhibit a yellow or orange hue may indicate a potential hazard, suggesting inadequate oxygen supply. Such a situation can result in the buildup of carbon monoxide within your living space, posing health risks to occupants. If you observe yellow or orange flames in a propane appliance, we strongly urge you to promptly reach out to AFC for immediate assistance.
