No cable, no battery — and a starting temperature that decides everything
A stove fan sits on the stove top and runs on the heat beneath it: a thermoelectric module turns the difference between the hot base and the cooler head into the few volts that spin the blades. No cable, no battery, nothing to switch on. Four figures decide between them and three are published. The starting temperature is the first and the most important: a fan that begins turning at 50 °C is working twenty minutes after lighting, one that needs 85 °C only joins in once the stove is fully up. The airflow in cubic metres per hour is published by most makers and is the figure most worth distrusting on its own, because it is quoted at the fan's best operating point rather than at the temperature a stove actually holds. The maximum surface temperature is the safety figure and the one that ends fans early — a module cooked above its rating fails silently, and stoves run hotter at the flue collar than in the middle of the top plate. Then the footprint and height, which sounds trivial until the fan has to stand clear of a rear flue spigot. We compare blades, airflow, power, start temperature, optimal range, maximum temperature, noise, overheat protection, material, dimensions and mounting.
6 blades, 60–250 °C, under 25 dB, 5.5 × 10.5 × 21.5 cm
Publishes a start temperature, an operating range, a noise ceiling and its own dimensions — which on this shelf is a complete set at the lowest price.
Best for: A stove with a flat top whose surface runs moderately rather than very hot
12 blades, two motors, starts ~60 °C, lifts at 345 °C, under 25 dB
Twelve blades on two motors, the most of anything on this shelf, with a stated 25 dB ceiling and a 345 °C lift point — and no airflow figure.
Best for: A larger room where the extra blade area is the point and the stove top has space for a wider fan
Starts at 55 °C, protection at 300 °C, thermometer and glove included
Arrives with a stove thermometer and a glove, starts at 55 °C, and protects at 300 °C — a bundle rather than a bare fan.
Best for: A first stove fan where the thermometer and the glove would otherwise be two more orders
8 blades, two motors, under 25 dB, thermometer included
Eight blades on two motors with a stated 25 dB ceiling, a thermometer included, and two percentage claims neither of which names a test.
Best for: A stove top with room for a wide fan, where the included thermometer saves a separate order
Pipe-mounted, 85–350 °C, ring for Ø 12–15.5 cm, thermometer included
Mounts on the flue pipe by magnet rather than standing on the stove, with an iron ring sized for 12 to 15.5 cm pipe and a stated mounting height.
Best for: A stove with a cold, stone or curved top where a free-standing fan would never start
6 blades, starts at 50 °C, stops above 350 °C
Starts at 50 °C — the lowest in this family — and states a minimum standing distance from the stove that the others leave out.
Best for: A stove that is run gently and would leave a higher-starting fan stationary
6 aerodynamic blades, under 25 dB, auto-lift protection, thermometer
Names soapstone appliances among what it suits, includes a magnetic thermometer, and states where to stand it so the fins can breathe.
Best for: A stove run at a moderate setting where the placement instruction is followed rather than guessed at
199 mm high, starts at 50 °C, 80–250 °C, max 340 °C, 350 ft/min
One of two fans on this shelf to publish an airflow, and the only one to publish its own height — 199 mm, for stoves with little clearance above.
Best for: A stove with a low mantel or shelf above it, where height is the constraint before anything else
Pipe-mounted, 4 blades, up to 230 CFM, max 350 °C, spare ring
A pipe-mounted fan publishing 230 CFM and a modified deflector plate, aimed squarely at stoves whose tops never get hot enough.
Best for: A soapstone or heavy-clad stove whose top stays cool, where a free-standing fan would sit still all evening
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
