What a beautiful choice in fireplace décor! These firestones are made of ceramic, meaning they won’t break or burst when exposed to the flames of your fireplace. We use a special stain when we make our river rocks that, unlike paint, won’t break or chip away with use. We feel that you deserve something that’ll stand the test of time, not a fireplace product that you’ll have to replace time and time again!

With this heater set you can choose what size you’d like. We have 20 inch, 24 inch or 30 inch available, meaning that it’ll fit most standard fireplaces easily! We have three color choices: white, black, or a combination of white, black and grey. Pick which one looks best with your modern or contemporary fireplace décor and see just how beautiful your ventless fireplace can be! This ventless fire set also includes control options so you can choose what works best for your lifestyle.

We’re a company devoted to our customers. We believe that happy customers come back and more than that, you deserve something that isn’t going to tear up easily. Other places don’t always prioritize their customers because they think that a cheap price tag on a cheap product is more attractive. In reality you spend more money buying the same poorly made product over and over. Give us a chance to show you why quality, American made fireplace products are better!
