How to Calculate Propane Usage for a Furnace
Propane is a popular choice for furnace fuel because it is cleaner than oil and more efficient than electric heating. However, it can be challenging to estimate how much propane your furnace will consume during a heating season. Below are some tips to help you calculate your propane usage:
- Check your propane tank gauge regularly: The most accurate way to determine your propane usage is to keep track of how much fuel is in your tank. Check the gauge before and after each propane delivery, and record how many gallons were added to your tank. This will give you a good idea of how much propane your furnace consumes per month or per season.
- Calculate your home’s heating load: Your furnace’s propane usage depends on how much heat your home needs. Factors like insulation, the size of your home, and the local climate all affect your heating load. You can use an online heating load calculator or work with an HVAC professional to estimate your home’s heating load. This will help you determine how much propane your furnace is likely to consume.
- Estimate your furnace’s efficiency: Furnaces have an efficiency rating, which tells you how much of the fuel they consume is converted to heat. The higher the efficiency rating, the less propane your furnace will use to heat your home. Most modern furnaces have an efficiency rating of 80% or higher, but older models may be less efficient. If you don’t know your furnace’s efficiency rating, check the owner’s manual or contact the manufacturer.
Once you have this information, you can use the following formula to estimate your propane usage:
Propane Usage (in gallons) = Heating Load (in BTUs) / Furnace Efficiency (as a decimal) / Propane Energy Content (in BTUs per gallon)
In the formula above, the Propane Energy Content value is usually 91,000 BTUs per gallon. This means that one gallon of propane contains 91,000 BTUs of energy.
| Heating Load (in BTUs) | Furnace Efficiency | Propane Energy Content (in BTUs per gallon) | Propane Usage (in gallons) |
|---|---|---|---|
| 100,000 | 0.85 | 91,000 | 1.24 |
| 200,000 | 0.90 | 91,000 | 2.07 |
| 300,000 | 0.95 | 91,000 | 3.03 |
Using the table above as an example, if your heating load is 200,000 BTUs, your furnace efficiency is 0.90 (or 90%), and the propane energy content is 91,000 BTUs per gallon, you can estimate that you will use about 2.07 gallons of propane per hour of furnace operation. This calculation can help you budget for propane deliveries and ensure that you always have enough fuel to keep your home warm during the winter months.
