Are propane and butane gasses interchangeable?

To verify this we recommend you consult the manual of your gas appliance. The calorific value of propane and butane differs. This might be significant for your appliance. The calorific value of commercial propane is 13.83 kWh/kg, the calorific value of commercial butane is 13.62 kWh/kg.

If the manual of your appliance states that the appliance works with propane as well as butane, you only need to use the right shut-off valve for the right gas. In such a case, you can switch between the gasses if this is what the manual of the appliance states and if you also replace the shut-off valve.
