The Golden Vantage Fireplace Heater is unique in that it’s a freestanding unit that can also be used as an insert. Its build from a sturdy steel frame and has a flat bottom so you can set it on the floor or even on top of a large piece of furniture. But, because it has a simple, thin boxy shape, you can build an enclosure for it or insert it into a fireplace if the dimensions are right. It has 2 heat settings and can warm up a room up to 400 square feet. There’s a remote control that lets you change the heat settings and make the flames brighter or dimmer. There are even realistic looking log inserts that help make the dancing flames even more like the real thing.
