Anyone else struggling to keep a small wood burner from absolutely roasting a single-room cabin?

Had exactly this problem in my 4x6m cabin last winter. The smallest Morso I could find was still like having a small sun in the corner — thing would hit 28°C within twenty minutes and I'd be sat there in a t-shirt in January wondering why I'd bothered with thermals.

What actually helped was a combination of things rather than one silver bullet:

• Damping down aggressively earlier than feels natural — don't wait until you're already roasting
• Smaller, more frequent loads rather than stuffing it full and walking away
• A good flue thermometer (got a cheap magnetic one off Amazon) so you're not just guessing where the burn is at
• Leaving a window cracked slightly on the opposite side to the burner — feels counterintuitive but regulates it surprisingly well

I also installed a small 12v fan on a thermostat running off my Victron/Fogstar setup to push warm air around more evenly, which means the area near the burner doesn't become unbearable while the far corner stays cold.

The honest truth is most "small" wood burners are still sized for rooms bigger than a cabin. Have you looked at the Hobbit stove by Salamander? It's genuinely sized for compact spaces and has much finer output control than the cheaper imports.

What's your current stove and how well insulated is the cabin? Those two factors change everything. I've seen people with poor insulation actually need an oversized stove just to compensate for the heat loss — which then becomes a nightmare to control.

Would be good to know more about your setup before suggesting anything else.

@CarlCole97 Ha, know this feeling well from my van days — small spaces and wood burners are genuinely tricky to balance. Have you looked at a boat stove rather than a cabin-specific one? The Hobbit or Salamander Hobbit Petit are designed for narrowboats where overheating a tiny space is a real concern. The key difference is they're built to tick over at much lower outputs.

Also worth considering your wood moisture content — bone dry wood burns hotter and faster than wood at around 15-20% which gives you a slower, more controllable burn.

One trick I use is keeping the air wash barely cracked once it's established. Sounds counterintuitive but it lets you nurse the fire rather than letting it rip. Takes a bit of practice mind you.

Had this exact battle in my shepherd's hut last winter! The hut's only about 4x3m so even the tiniest burner was brutal.

What helped me was fitting a Wallas diesel heater instead for the really cold nights — much easier to dial in. But if you're set on wood, have you looked at the Hobbit stove by Salamander? It's specifically designed for tiny spaces and has a built-in airwash that lets you throttle it right back without it going out.

Also — and this sounds daft — have you tried just leaving the flue damper barely cracked? Takes a bit of practice but you can really slow the burn down once you've got a decent bed of embers going.

What's your insulation situation like? Sometimes overheating is actually a sign the cabin is too well insulated for the stove output, weirdly enough.
