Impress your guests with our Megamaster Ontario 12kW Cast Iron Fireplace, big enough to keep everyone (and the dog) warm. It is effective in heating rooms ranging between 96-120m² in size. Built with a closed combustion system, the Ontario 12kW 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.
