How much fuel does a gas fireplace consume and how much does it cost to operate?
The consumption and cost of operation may vary depending on the region, the gas utility company, or the type of fuel. Following is an example of how to calculate the approximate cost of operating a 25,000 BTU fireplace at the maximum flow rate. Natural gas: One cubic meter (1m3) of natural gas produces an average of 35,301 BTU. At the maximum flow rate, a 25,000 BTU fireplace will consume 0,708m3* of natural gas per hour (i.e. 25,000/35,301). If natural gas is priced at 0,365$* per cubic meter, it would cost 0,26$* per hour to operate the fireplace at its highest setting. The same calculation applies for the minimum flow rate. Propane (LP): One litre of propane produces an average of 29,059 BTU. At the maximum flow rate, a 25,000 BTU fireplace will consume 0,86 litre of propane per hour (i.e. 25,000/29,059). If propane is priced at 0,45$* per litre, it would cost 0,39$* per hour to operate the fireplace at its highest setting. The same calculation applies for the minimum flow rate. *Co
