Regulator Sizing

To size your regulator, follow these steps:

• Calculate the Total BTU Demand: Add up the BTU requirements of all the appliances connected to the propane tank.
  
  Determine the Flow Rate: Divide the total BTU demand by 1,000 to convert BTUs to cubic feet per hour (CFH). This will give you the required flow rate for your regulator.
• Select a Regulator: Choose a regulator with a flow rate capacity equal to or greater than the calculated flow rate. Ensure the regulator’s inlet and outlet pressures are compatible with your system.
  
• Materials and Construction: Select a regulator made from high-quality materials that can withstand the rigors of outdoor use, such as brass or stainless steel.
  
• Safety Features: Look for regulators with built-in safety features, such as overpressure protection, which can shut off the gas supply in case of excessive pressure.
  
• Installation: Consider hiring a professional to install and inspect your propane system to ensure safety and compliance with local regulations.

Choosing the right regulator for a 100lb propane tank is crucial for the safe and efficient operation of your propane-fueled appliances.
