We recently completed a Heat-Kit masonry heater core installation in eastern Maryland. Our clients wanted the clean, comfortable efficient heat of a masonry heater in their existing home’s living room. The core is a corner unit: the side heat exchange channels are at 45˚ angles to the front. The core also has a pre-cast white bake-oven. The high temperature core is completed in the photo below, ready for the final facing stone veneer.
