How it works

A fan that runs on fire alone.

No plug, no batteries, no switch. EvenHeat turns your stove's own heat into a gentle flow of warm air, and sends it to the side of the room that's always cold.

  • No electricity needed
  • Silent, 25 dB or less
  • Starts from around 50°C

Three steps, zero electricity

From fire to fan in minutes.

  1. Step 1

    Heat in

    Set it on your stove top. The base soaks up the heat while the fins on top stay cooler.

  2. Step 2

    Power made

    That temperature difference makes a small current that turns the motor.

  3. Step 3

    Warmth out

    Six blades push warm air across the room, towards the spot that's always cold.

The ceiling trap

Your stove makes plenty of heat. It just goes up.

Warm air rises and tends to collect near the ceiling. The stove side can feel too hot while the seating area stays cooler, and adding more wood mostly makes the hot side hotter.

With EvenHeat

Room with an EvenHeat fan The same room with a fan on the stove. Gentle paths of air move outward from the fan into the living space toward the seating area, while some still curve upward. Assisted air circulation

Built to last

Quiet on the outside. Clever on the inside.

Every part is chosen to do one job well, winter after winter.

  • Six anodised aluminium bladesLight, rigid and heat-resistant, for a steady, quiet flow.
  • Bimetal safety baseLifts the fan away if the stove top runs too hot.
  • Starts on a warm stoveGets going from around 50–75°C and works up to 350°C.
  • No plug, no batteriesPowered only by your stove's heat. Nothing to charge, ever.

The science

Discovered in 1821. Now on your stove.

When one side of a thermoelectric module is hot and the other is cooler, a small electric current flows. The stove heats the base, the fins release heat to the room air, and that temperature difference runs the motor that turns the blades.

How a temperature difference powers the fan Simplified schematic. The stove heats the fan's base. Fins above release heat to the room air. The temperature difference across a thermoelectric module makes a small electric current, which runs a motor that turns the blades.

Placement

Get the most from it.

Three small things make the biggest difference.

  • A flat, clear spotStand it on a flat part of the stove top so the whole base is in contact, usually towards the back and to one side of the flue.
  • Face the living spaceTurn it towards the part of the room you want warmer: the sofa, the hallway, the far corner.
  • Keep the fins clear and watch the thermometerLeave room around the fins for cooler air. When the fan slows, the stove is cooling: time for another log.

The fan sits flat on a clear area beside the flue, with its cooling fins unobstructed, facing out toward the front of the stove and the living space.

What to expect, honestly

No hype. Just how it is.

  1. A gentle flow

    A steady stream of warm air, not a breeze you can feel from across the room.

  2. Starts as the stove warms

    It begins turning a few minutes after lighting and speeds up as the stove gets hotter.

  3. Best on freestanding stoves

    Made for wood-burning and multifuel stoves with a flat top. Inserts often stay too cool.

  4. Moves heat, doesn't make it

    It sends your stove's heat further. That's why you get 30 nights to prove it.
