Frequently Asked Question 



Which gas fireplace insert puts out the most heat? 

Whether it is vented, ventless or direct vent, every gas fireplace insert is efficient in their ways. In terms of heat output, direct vents are the most efficient ones. The reason is in the direct vent system.

Is it OK to leave a gas fireplace on all night?
