Propane gas furnaces are a type of heating system that uses natural gas as fuel. They are an efficient and popular choice for home heating.
These furnaces require less maintenance and are more reliable in cold weather. They provide consistent heat and can be easily adjusted to preferred temperatures.
Natural gas furnaces release fewer greenhouse gasses, making them a greener option.
Plus, they work even during power outages since they use stored natural gas instead of electricity.
Propane Gas Furnace
Propane gas furnaces offer an alternative to natural gas for heating. Their fuel type is LPG gas, with an efficiency rating of 90-98%.
Though the initial cost is higher than electric furnaces and oil-fired boilers, the operating costs are lower.
Propane is widely available across the US, making it a preferred choice for those living in areas without piped natural gas.
Comparison of Natural Gas vs Propane Furnace
When it comes to home heating, there are a few fuel sources to choose from. Natural gas and propane furnaces are two of the most popular options.
Here’s a table showing their differences in efficiency, cost, and availability,
| Factor | Natural Gas Furnace | Propane Furnace |
| Efficiency | 90-98% | 80-95% |
| Cost per Unit of Heat Generated | Cheaper than Propane | Pricier compared to Natural Gas |
| Burns Cleaner? | Less Greenhouse Gas Emissions. | No |
Other Factors to Consider
To ensure that you make the correct choice when buying a gas furnace, it’s important to consider several factors beyond just cost and efficiency.
Climate Zone and Home Size
For optimal home comfort, it’s essential to consider both the climate zone and home size.
This helps in choosing the right HVAC system, insulation, and energy-efficient appliances.
It’s important to note other factors, like type of construction and insulation, also help determine the right HVAC system.
