This is basically what powers the Voyager space craft, with the slight difference that instead of a coal fire they have a lump of red hot plutonium :-)

I just checked and 345°C is equal to 653°F. I'm sure you would notice quite soon if it was that hot near the stove. Great review!

It is kind of funny, it is exactly the right tool for the job. All the criticisms seem to be because it is not like the other all the other overpowered devices. After seeing your videos, I am thinking I will get one or two for my pellet stove to cover a few cold spots.

The fan works off the Pelletier effect. This occurs in certain semiconductors and usually is utilized for small coolers. In this setting, dc current causes one side of the semiconductor to cool and the other to heat. In the fan the process is reversed; when one side of the semiconductor is heated and the other cooler - thence the fins to cool that side- electricity is generated. Now you know

I have the same fan - maybe a slightly later model as the motor is black (slightly more aesthetically pleasing) and there are curvy bits at the bottom of the vents (£35.99 - a song). It works fine and although it's certainly not a hurricane, I have one of those old fashioned clothes airers suspended from the ceiling of my boat close to the stove and i notice a smidge of fluttering laundry when the fan kicks in. I also plundered the boat funds for a simple stove thermometer (£5.99) and it needs to get up to around 100 degrees C to start working. So far I have not exceeded about 120 degrees on my stove as it hasn't been cold enough yet!

I ought to buy a stove thermometer but haven't got around to it. I'm curious to know how hot mine really gets (other than "very hot"!)
@argrundy8 жыл бұрын
Just to add... the hotter the stove becomes, the faster the fan spins. Had my stove up to 200 degrees lately (you know, cos I've got a stove thermometer and all) and there was a very decent breeze :D

Nice review thx. Also like your Narrow-boat vids, im a fan. Lastly, i have something akin to family stationed at Lakenheath and am somewhat jeleous as I'd enjoy a trip to dark satanic mills of Englands green and pleasent land

We have had one for about 8 years on our wood stove, it will run 24/7 during the winter months, I even had to replace the motor (3 volt) $3 off ebay because the bearing started squeaking. Does it blow air? NO, not really. Going all out a candle 1 foot in front of it will barely flicker, convection up-draft is far stronger, but it does give a visual indication as to how the stove is doing. It was a Christmas gift so did not cost us anything. I would not pay more than $20 if I had to replace it.

I agree and mine's broken now; it started squeaking like yours but now won't go round at all.

The base of the fan needs to be in contact with a VERY hot surface, is your mantle VERY hot?

en.wikipedia.org/wiki/Thermoelectric_effect As you mention, David, the FINS are used to keep the top half cool. The fan sucks air over them to help this.

Galleon Fireplaces stove fan uses an electricity generator based on a Peltier module, the module is placed between the fan hot basement and relatively cool fan top, it uses the thermoelectric effect based on the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple created from two different material plates, for example this device can be modified to cool something in exchange a supplied electric energy, and this conversion is widely y used in mobile electric coolers' boxes, and here this thermoelectric Peltier effect is used to transform heat difference to electricity to use for an electric motor with propeller to create hot air circulation and cool down top part/radiator of fan, remember the top part shall be cool comparing to the hot fan basement. The Peltier module efficiency isn't high, but really good enough for this fan and its purpose, the fan's electric motor that doesn't depend on an outer electric source. kzbin.info/www/bejne/iHSUZ4Ctr6ukbqM
