Do Gas Log Sets Give Off Heat?
Yes, though how much heat will vary. Generally, vented gas log sets don't put out as much heat as ventless or vent-free gas log sets. In addition, gas log sets with a larger burner tend to put out more heat as well. To find out how powerful a gas log set is, you'll want to look for its BTU output. BTU stands for British Thermal Unit; it's a standard measure of temperature change used in the HVAC industry.


How Much Propane/Natural Gas Does a Gas Log Set Use?
This will depend on the size and heat output of the gas log set. There's a direct correlation between larger flames, greater BTU output and total fuel use. A propane gas log set with an output of 50,000 BTU will use up about a half gallon of propane every hour. A natural gas log set with the same output will use about 50 cubic feet of natural gas in that hour. At average natural gas prices, that means it costs about 50 cents to run a natural gas log set for an hour.
How Do I Clean a Gas Log Set?
Cleaning a gas log set can generally be done with soap and warm water if done regularly. If you need to remove more intense soot build-up, we offer a number of high-quality fireplace cleaning products that are sure to get the job done.


How Do I Measure a Fireplace for a Gas Log Set?
To accurately measure your firebox for a gas log set, you'll need to take measurements of the height, depth, front width and rear width of the space. After you have those measurements, you can compare them to the size of gas log sets while shopping to ensure there is sufficient space. Each burner will have a recommendation from the manufacturer of the minimum firebox size.
How Do I Choose a Gas Log Set?
Finding the right gas log set for your home means considering the size, heat output, design and price, just to name a few factors. We carry hundreds of options, so the best way to find the right log set for your fireplace is by using our in-depth gas log set buying guide.


What's the Difference Between "Vented" and "Vent-Free" Gas Logs?
Gas log sets create exhaust gasses as a byproduct of combustion. Vented gas log sets require a chimney to expel those gasses, while vent-free gas log sets don't require ventilation to operate safely. Also known as ventless gas log sets, these units do tend to have a higher heat output, but their flames tend to be smaller. Vent-free gas log sets are restricted by some building codes, so be sure to check with your local authority before buying.
How Much Do Gas Logs Cost?
Gas log set prices will vary depending on size, brand and features. Our selection of gas log sets starts at about $400, while a large gas log set with all the bells and whistles can cost as much as $10,000 dollars. We've almost certainly got a gas log set that meets both your needs and your budget.
