What is a stove fan?

Stove fans are powered completely by the heat generated from your wood burning or multi-fuel stove. They typically sit on top of the stove and do not require any electricity to function, so you don’t need to worry about any extra batteries or electric mains to run.

To function properly, stove fans must draw cooler air from behind them to properly function. Because of this, the positioning of your fan on your stove body is therefore incredibly important for it to work properly. If placed too far forward, it might not be able to run!

How do stove fans work?

When a Stove Fan is placed on a working wood burning stove, heat is conducted from the surface of the stove, travelling up from the aluminium base of the fan, to the underside of the Peltier device. The Peltier device generates electricity by having one side hot and the other side cooler (known as a ‘thermal difference’). This temperature difference creates a ‘potential difference’ (a voltage) in the circuit. This voltage powers the motor, which in turn drives the fan.  The fan requires no batteries or external power. Heat is conducted though the base of the fan and converted to electricity, which powers the fan motor. As the heat from the stove reduces, the fan automatically slows and stops.

Do I need a stove fan?

One of the key differences a stove fan can make to your home is the dramatic increase in the warmth that you receive from your stove.  Stove fans are designed to circulate the warm air from the stove evenly around the room, directing warm air away from the fireplace and flue pipe, instead of it simply rising to the top of the room. This ensures that it doesn’t escape or heat rooms above when you really want it to warm the room that you’re in. You don’t have to wait for the stove to get up to optimum temperature before the stove fan works either, with many starting to operate from as low as 45 degrees! This means that you can enjoy the warmth of your stove straight away!

Having a more effective flow of heat around the room also means that you’re likely to spend less money on fuel, as you will use less because heat is circulating around the room better. You won’t be tempted to throw an extra log on the fire if the room drops cool, instead, you’ll get to enjoy a consistent temperature the whole time the stove is burning.

Without a stove fan, you are in danger of wasting a lot of the warm air produced from your wood burning or multi-fuel stove. Due to the fact that hot air rises naturally, you may find that the room with your wood burning stove is cooler than those above it, which is the exact opposite of what you want!
