The Chubby 8 has an 8kW output with a large glass window. It uses the Chilli Penguin clean burn and air wash system, giving a lovely clear view of the fire and high efficiencies. Like all our domestic stoves the Chubby 8 is very controllable.
The penguin disc on the front of the stove is an air boost disc, it is designed to balance open as the fire establishes, then swing down. It should be free swinging. The primary and secondary air control knobs can be used to achieve the burn that you want and be adjusted for the fuel type.
