Quick Answer
A single propane tank can support multiple heaters, but the total BTU (British Thermal Unit) demand must not exceed the tank's capacity, typically 80,000 to 100,000 BTUs.
Propane Tank Capacity
When sizing a propane tank for multiple heaters, it’s essential to consider the total BTU demand. A general rule of thumb is to choose a tank with a capacity 1.5 to 2 times the total BTU requirement. For example, if you have three heaters, each with a 20,000 BTU output, the total demand would be 60,000 BTUs. In this case, you would need a tank with a capacity of at least 90,000 to 120,000 BTUs.
Heater Sizing and Compatibility
Not all propane heaters are created equal. When selecting multiple heaters, ensure they are compatible with each other and the propane tank. Look for heaters with similar BTU outputs and fuel consumption rates to simplify tank sizing and ensure efficient use of propane. Additionally, consider the heaters’ pressure requirements, as some may require a higher pressure regulator than others.
Installing Multiple Heaters
When installing multiple heaters, it’s crucial to follow proper safety protocols to avoid overloading the propane tank and potential gas leaks. Install a regulator to ensure a consistent pressure supply to each heater, and use proper piping and connections to prevent leaks and damage to the tank. Consider installing a tank gauge to monitor propane levels and prevent over-dispensing.
