How Much Propane Does a Furnace Use Per Month?


A propane furnace is a popular heating option for many homeowners due to its efficiency and cost-effectiveness. However, one common question that arises is how much propane does a furnace use per month? The answer to this question depends on various factors such as the size of your furnace, the climate you live in, the insulation of your home, and your heating preferences. In this article, we will explore these factors in detail and provide you with a general idea of how much propane you can expect your furnace to consume per month.

Furnace Size

The size of your furnace plays a significant role in determining its propane consumption. Generally, larger furnaces will consume more propane compared to smaller ones. The size of your furnace should be chosen based on the heating requirements of your home. It is essential to consult with a professional HVAC technician to ensure that your furnace is appropriately sized for optimal propane usage.


The climate you live in also affects the propane consumption of your furnace. In colder regions, where the winter temperatures are consistently low, furnaces will need to work harder and consume more propane to maintain a comfortable indoor temperature. On the other hand, in milder climates, the furnace may not need to run as often, leading to lower propane consumption.

Home Insulation

The insulation of your home plays a crucial role in propane consumption. Well-insulated homes retain heat more effectively, reducing the workload on the furnace. If your home is poorly insulated, the furnace will have to work harder and consume more propane to compensate for the heat loss. Investing in proper insulation can help lower your propane consumption and save money in the long run.

Heating Preferences

Your heating preferences also impact the amount of propane your furnace uses per month. If you prefer to keep your home warmer, the furnace will need to run more frequently, resulting in higher propane consumption. On the other hand, if you are comfortable with a slightly lower indoor temperature, you can set the thermostat accordingly and reduce propane usage.

Efficiency of the Furnace

The efficiency of your furnace can significantly impact its propane consumption. Older furnaces tend to be less energy-efficient and may consume more propane compared to newer, high-efficiency models. Consider upgrading to a more efficient furnace to reduce your propane usage and lower your heating costs.


While it is challenging to provide an exact figure for how much propane a furnace uses per month, considering factors such as furnace size, climate, home insulation, heating preferences, and furnace efficiency can give you a general idea. Consult with a professional HVAC technician to assess your specific requirements and determine the most efficient propane consumption for your furnace. By optimizing these factors, you can reduce your propane usage, save money, and contribute to a more sustainable environment.
