We have an old F3 Jøtul in our cabin at Rena, we are planning on staying there all through the winter. The stove we have works very well, but it is not clean burning, and burns through the wood really fast.

I'm trying to find a new stove that could heat us well during cold winters on Innlandet, and burn more efficiently.

Our cabin is not really well insulated, but is only 100 square meters. I would prefer something that can burn through the night, and minimize the need for using heat pumps, any suggestions?
