Who should be contacted to obtain the heating value of the gas used?

The local building authority
The gas supplier
The appliance manufacturer
The utility company

The correct answer is: The gas supplier

The heating value of the gas, which indicates the amount of energy produced when the gas is combusted, is typically provided by the gas supplier. The gas supplier has access to the specifications and chemical composition of the gas they deliver, which can vary based on the source and type of gas (such as natural gas, propane, or butane). This information is crucial for gas fitters to ensure that appliances are installed correctly and operate efficiently. While the local building authority, appliance manufacturer, and utility company might have relevant information about gas appliances or codes, they do not usually provide the direct heating value of the gas itself. Therefore, contacting the gas supplier is the most reliable way to obtain the specific heating value needed for accurate appliance performance and installation calculations.
