Preview: Comparison 17 – Four wood stoves after a week of test burns

KELDERBY STOVES · SHOWROOM BURN TEST

Four stoves, burned side by side.

We ran each stove for a week on seasoned ash, measured the smoke at the flue and timed how long the top plate took to reach 200°C. The Pike 5 came out cleanest and quickest, which is why it is the one we fit most.
