Electric heat is more efficient
Secondly, electric heat is 100% efficient, while propane furnaces are only about 90% efficient. This difference in efficiency becomes more significant as energy usage increases, resulting in higher costs for propane heating. Electric heat pumps also have lower repair costs since their systems are generally less complicated.
Thirdly, electric heat eliminates concerns about fuel storage and safety. Propane requires a tank for storage, which takes up space and may be subject to additional delivery fees. Electric heat, on the other hand, does not require fuel storage, making it a safer option.
Additionally, electric heat is a cleaner energy source than propane. Propane burns cleaner than electricity generated from fossil fuels, producing fewer carbon emissions and having a lower environmental impact. However, as more energy moves towards renewable sources, the environmental impact of electricity will continue to decrease.
While propane heat offers advantages such as warmer air, quicker heating, and reliability during power outages, electric heat is more efficient in terms of cost, energy conversion, safety, and environmental impact. Homeowners should carefully consider their specific needs, local energy costs, and climate conditions before making a decision.

Propane is a cleaner, eco-friendly option
Propane is a clean-burning fuel that produces significantly fewer greenhouse gas emissions than electricity generated from fossil fuels. Propane is recognised as a "green" energy source and is listed as an approved alternative fuel in the Clean Air Act of 1990 and the National Energy Policy Act of 1992.
Propane is non-toxic and does not contaminate the soil or water, making it a safer and more environmentally friendly heating option. It produces minimal emissions, and because it is gas, it doesn't spill, pool, or leave a residue.
Propane furnaces are also more energy-efficient than electric heat pumps, which dispense air at 95°F (35°C), just below the average human body temperature of 98.6°F (37°C). In contrast, propane furnaces consistently supply air at 120°F (48.9°C) and can heat air to temperatures between 130°F (54.4°C) and 140°F (60°C). This higher temperature output creates a more comfortable and cozier environment, especially during the colder months.
Propane is also a more reliable energy source than electricity, which is subject to power outages. Propane can be safely stored in a tank on your property, ensuring a consistent fuel supply even during extended outages. This reliability is especially beneficial in areas prone to severe weather and frequent power disruptions.
Overall, propane is a cleaner and more eco-friendly option than electricity for homeowners seeking high performance, increased efficiency, and dependability in their furnace while also minimising their environmental impact.
