A pilot light will burn approximately 1,000 BTU’s per hour (720,000 BTUs per month). 100 cu. ft. of gas (1 CCF) = 102,700 BTUs therefore the pilot uses 7.01 CCFs per month Current cost per CCF of natural gas = $1.10* therefore the cost is about one penny per hour or $7.71 per month
The average gas log set will burn approximately 30,000 BTUs per hour.
100 cu. ft. of gas (1 CCF) = 102,700 BTUs therefore the log set uses about .29211 CCFs per hour of
Current cost per CCF of natural gas = $1.10 * therefore the cost is only $.32 per hour of operation!
A ventless gas log set or heater is over 99% efficient. The Hearth, Patio and Barbeque Association (http:/ /www.hpba.org/fuel-efficiency-calculator/) estimates that a homeowner can save approximately 300 CCF per year by heating the rooms the family occupies the most and running the central heating system less. This equals approximately $300 per year at current retail natural gas prices*.
www.ehow.com estimates the costs savings to be approximately $200 per year assuming the annual usage is 100 hours and the average cost of a cord of wood is $200.
Outdoor gas lanterns use approximately 1,280 BTUs per hour (921,000 BTUs per month) 100 cu. ft. of gas (1 CCF) = 102,700 BTUs therefore the lantern uses 8.97 CCFs per month Current cost per CCF of natural gas = $1.10* therefore the cost is $9.87 per month.
* The current natural gas price is based on January 2011 Columbia Gas of Pennsylvania rates including Gas Cost, Distribution Charges and Gas Supply Charges.
