Gas Fireplaces. We Are Never Under Sold! Why buy a gas fireplace? Homeowners who want the warmth of a hearth without the bother of burning wood are now turning to gas fireplaces. With gas flames that curl around woodlike ceramic logs and look so incredibly real, these appliances offer a true fireplace at the touch of a switch and also can be had with a remote. Gone are the days when a new fireplace meant a masonry chimney rising feet above the nearest roof. Today, many fireplaces install with a simple cut in the exterior wall for venting.
