Wood inserts are devices designed to be installed inside traditional fireplaces, improving efficiency and heat control. These devices are made of resistant materials such as cast iron or steel and have optimized combustion systems that allow greater energy efficiency and lower smoke emissions. In addition, they offer a modern and functional design that easily integrates into the existing structure of the fireplace, providing heat to several rooms evenly. They are ideal for those looking to modernize an open fireplace and make the most of wood as an energy source.
