Low pressure propane burners have larger orifices, and high pressure burners have smaller ones. I am running on low pressure and there is a handy chart which lets you determine the orifice size from the BTU rating of your burner.
Selecting the right burners and pumps is crucial for the efficiency of your beer brewing stand. High-performance propane burners provide a consistent, high heat source, ensuring a smooth brewing process.
