Yes and it's popular due to both efficiency and convenience. Natural gas is inexpensive and burns much cleaner than that of wood burning fireplaces. Have a professional install the gas line so that everything will be up to code.
This depends on the amount of time will use your fireplace. An average cost of a thermostat for 100,000 BTUs runs $.50. If you calculate that, to operate a 12,500 BTU fireplace for one full hour you would use approximately $.12. When you weigh out the difference between gas and wood burning fireplaces; using natural gas can provide you with as a 75% savings.
Gas fireplaces with a standing pilot light will operate during a power failure because there is a continual gas supply.
BTU stands for British Thermal Unit; a measurement that represents heat output. Typically 10,000 BTU can heat approximately 500 square feet.
A direct-vent fireplace is a sealed combustion appliance where air is drawn from outside and all smoke and vapor is vented directly outside.
Vented gas logs can only be used in a wood burning fireplace. A coal burning fireplace is too shallow. Vented gas logs are not recommended for a stove due to safety concerns.
Direct-vent will give you a great look and a good amount of heat with little moisture. Vent-free will give you lots of heat and looks good but the number one complaint about vent-free is it puts out too much heat. If the vent-free is sized correctly to the room, you will not have a problem with heat or moisture.
