Is a ventless gas fireplace safe to use indoors?

Do ventless gas fireplaces produce real flames?
Absolutely! Freestanding ventless gas fireplaces use real flames to provide warmth and ambiance. The flames are created by igniting natural gas or propane, offering a realistic fireplace experience without the need for wood or chimney maintenance.
Can I use a freestanding ventless gas fireplace as a primary heat source?
It depends on the size of the fireplace and your room. These units are great for zone heating and can warm spaces from 300 to 1,000+ square feet, but they may not be sufficient as the sole heat source for large or multi-room homes.
