Q: I know vented gas log fireplaces are inefficient to run, but how much does an hour of use cost if you are burning propane in an average vented gas log? – DR
A: Hi Dr, Well the cost will depend upon your cost of propane and the BTU of your device but let’s make an estimate:
Say you have a 45,000 BTU unit and Propane costs $3 per gallon. The cost would be about $1.50 per hour to operate it. (Since a 90,000 BTU unit will consume 1 gallon in an hour)
Keep in mind as well that you are getting very little if any heat gains from this fuel consumption. That is the travesty of vented gas logs. – Jason
