Heater Propane Consumption Calculator
Propane heaters are a popular choice for heating spaces, but understanding their consumption rates is crucial for efficient use and cost management. Here's a comprehensive table detailing propane consumption for various heater BTU ratings:
| Heater BTU Rating (BTU/hr) | Gallons per Hour | Gallons per Day (24 hrs) | Gallons per Month (30 days) | Burn Time with 100lb Tank (hours) |
|---|---|---|---|---|
| 6,000 | 0.28 | 6.72 | 201.6 | 357.14 |
| 10,000 | 0.46 | 11.04 | 331.2 | 217.39 |
| 15,000 | 0.69 | 16.56 | 496.8 | 144.92 |
| 25,000 | 1.15 | 27.60 | 828.0 | 86.96 |
| 30,000 | 1.38 | 33.12 | 993.6 | 72.46 |
| 40,000 | 1.82 | 43.68 | 1301.4 | 54.35 |
| 50,000 | 2.27 | 54.48 | 1634.4 | 44.05 |
Key Points to Remember
- BTU Rating: The British Thermal Unit (BTU) rating indicates the heating capacity of the heater. Higher BTU ratings mean more heating power but also higher propane consumption2.
- Consumption Rates: Propane consumption increases proportionally with the BTU rating. For example, a 50,000 BTU/hr heater uses about 8 times more propane than a 6,000 BTU/hr heater.
- Daily and Monthly Usage: Consider your heating needs when selecting a heater. A 25,000 BTU/hr heater running continuously would use about 828 gallons of propane per month.
- Tank Size Considerations: The burn time with a 100lb propane tank varies significantly based on the heater's BTU rating. A 10,000 BTU/hr heater would last about 217 hours, while a 40,000 BTU/hr heater would only last about 54 hours on the same tank2.
- Efficiency: Remember that these figures represent continuous use. Actual consumption may be lower depending on thermostat settings, insulation, and usage patterns.
- Comparison with Other Appliances: For context, a gas cooktop typically uses 65,000 BTU/hr or about 5 to 10 gallons of propane per month, while a tankless water heater uses about 40,000 BTU/hr or 1.5 gallons per day3.
By understanding these consumption rates, you can better plan your propane usage, estimate costs, and choose the right heater for your needs. Always consult with a propane supplier or heating professional for advice tailored to your specific situation.
