Retro with streamline design and finishes, our Megamaster Walden 8kW Cast Iron Fireplace is effective in heating rooms ranging between 64-80m² in size. Built with a closed combustion system, the Walden 8kW Cast Iron Fireplace heats up much hotter than a conventional open fireplace. Heat generated inside is locked in and will burn at higher temperatures with the door closed. For optimal heat, ensure that the room is well insulated. Can be installed with a top or rear flue pipe that is sold separately.
