Been wrestling with this one since I first got my cabin sorted a couple of winters back. The log situation was genuinely depressing — I'd stockpile what felt like a mountain of seasoned oak and birch, then watch it disappear by February like it was nothing.
What changed things for me was treating it less like a heating problem and more like a fabric problem. Once I properly addressed the gaps around my door frames and sorted some decent sheep's wool insulation under the floor, my little Morso squirrel stove suddenly felt like it had doubled in output overnight. Same logs, noticeably warmer.
I also run a small Victron setup with a couple of panels on the roof, which means I can run a basic oil-filled radiator through the shoulder seasons — October and late March mainly — without touching the stove at all. That alone probably saves me half a cubic metre of logs annually.
A few things that genuinely helped:
- Thermal mass — a few old house bricks stacked near the stove hold heat for hours after the fire dies down
- Burning hot and short rather than slow-smouldering all day (better for the flue too)
- A decent moisture metre — wet wood is basically just expensive steam
Wondering if anyone's experimented with rocket mass heaters for a smaller cabin footprint? I've been tempted but nervous about the build commitment and whether it suits a weekend-use setup rather than a permanent dwelling.
Would be good to know what other people are burning too — I've had mixed results with mixed hardwoods from local sawmills.
