The Stove Top Fan is the answer to the question that many wood burner owners ask themselves! The question, why isn’t the whole room warming up, it’s only warm around the wood burner? The reason for this is that heat convects from the source, meaning it rises, in this case up to the ceiling. The warm air drops down as it begins to cool but it’s not as warm as you might like it to be.
So how does the Stove Top Fan help to fix this problem then? As your burner heats up the fan will start to spin, this pushes the hot air out into your room before it has the chance to convect upwards to the ceiling. Meaning everyone in the room benefits from the warmth from your stove.
The Stove Top Fan runs for free
What, the stove top fan has no running costs at all? Yes that’s right, you don’t need an electricity supply or batteries to run this baby, it generates it’s own electricity through heat differential. The fan sits on top of your stove, this means that the base of the fan is hotter than other areas of the fan assembly. About half way up the fan there is a semiconductor that uses this heat difference to generate a small amount of electricity, enough to spin the fan. As your stove top gets hotter the fan spins faster, shifting more warm air into your room. You can find a more in depth explanation on these fans work in this wiki.

Types of Stove Top Fan
There are many different types of fans on offer, they all work from the same basic principle, ie, shifting the warm air into your room and using that heat differential to generate electricity to spin the fan.
Some have a single fan with two, three or maybe four blades, others are a multi fan construction, meaning they have two fans in the same structure. This would lead you think that because there are two fans they will shift even more warm air, this might well be the case, I don’t know as I don’t have one of this type of Stove Top Fan.
