What are the 3 steps to determine total gas demand?

• A. Locate the propane-fueled appliances currently installed in the customers home; Determine the BTU/hr input ratings of all appliances currently serviced by the propane system and all appliances that may be added in the future; Take the BTU/hr input for all existing and future appliances and add them together
• B. Locate the propane-fueled appliances currently installed in the customers home
• C. Determine the BTU/hr input ratings of all appliances currently serviced by the propane system only
• D. Take the BTU/hr input for existing appliances and ignore future additions

Answer: (A)

Determining total gas demand means accounting for every appliance that could draw propane, not just what’s installed today. First, locate all propane-fueled appliances currently in the home. Then, gather the BTU/hr input rating for each appliance, including those that may be added in the future. Finally, add all of those BTU/hr inputs together to obtain the total gas demand. This approach sizes the system for both present needs and potential growth, ensuring the equipment can supply peak loads even when new appliances are installed. If you skip future additions, you risk undersizing the system; if you only consider current appliances, you may underestimate demand.
