The Klover Venus is a very efficient wood burning stove that has a beautiful flame pattern when it burns. It will throw out up to 8kW of heat to the room, although it is controllable so you can turn it down if needed too. The ability to connect the Venus to an external air duct makes it a good match for warming homes which have been made more airtight.
