Posted Aldi fan the other day, but after some research I went for this one instead, which has made it to some top 10 reviews. Also next day delivery for £1.99 and Free Extended 2 Year Warranty. :smile:
The blurb:
Heat powered stove fan - increases the efficiency of your freestanding stove oven or wood/ log burner to generate warmth economically.
Eco-friendly and self-powered - a thermoelectric module acts as a small generator to power the fan’s motor. No batteries or electricity required!
Operates automatically between 60 - 300°C with speed self-regulating according to the temperature in the room. Circulates 130 - 150 CFM.
Extremely quiet operation, compact size, no installation required - 22.5 x 15 x 9.5cm - made from strong black steel.

I've got an old gas fire in my living room and it kicks the heat out but only directly around the fire... Rest of the room is still cold unless I have it on full blast. Wondering if this would be any good to pit on top of or in front of the fire to make the rest of the room warmer?

Yep. But bear in mind that humans perceive radiant heat as much more warming than air temperature - this is one of the reasons we have radiators instead of air heaters. You may find it an equally good investment to get some better insulation in the room, particularly if you can put any reflective insulation behind the heater.
Actually more blades aren't necessarily better - the more you have, the closer each blade is to the next one, and so the more turbulent airflow the blade is exposed to. This increases noise for a given fan/airspeed and decreases efficiency. For something like this where efficiency and noise are important, three blades is likely to be more desirable.
This is the same reason that large wind turbines typically use three narrow blades.

Makes sense, so I have cancelled the 4 fan version and gone for the 3. Cheers.

Bad advice about the gas fire.

Thanks for your criticism, would you care to make it constructive?

Yes. Sticking a stove fan on top or anywhere near a gas fire would be pointless and dangerous so don't do it and don't advise anyone to do it. Although you didn't tell him directly to do it you did give him other options when the correct advice would be to don't even consider it. As I did.

Surely it depends on the design of the setup? We have a gas fire with a flat iron top which works fine. I admit; I thought he had already understood how the fan worked and wasn't planning to put this fan in a literal open fire though.

I've never seen a cast iron gas fire. The heat on top of a stove is usually 300+ degrees. I don't think a cast iron gas fire would ever get near those temperatures(probably not safe). Stove fan doesn't start to spin until the stove around 300. Just didn't want anyone to waste any cash, that's all.

Oh well thanks for the advice everyone, no I hadn't bought it in any case, I just thought it might push the heat around the room a bit, but would probably be better with a radiator fan thing... Its annoying having to have the sofa in front of the fire to feel warm! And idk what you would call the type of gas fire... Very old lol, a lot of the heat seems to warm the carpet in front of it

That's fair, though this listing does say that the fan starts at 60*C so it should work if there is somewhere that conducts heat from the fire and doesn't have direct flames on it

Won't work. It actually heats up the fan. As in red hot steel (the stove) on steel(the fan) to a similar heat which then starts the fan turning.. If you have bought it you need to cancel.
Ive had a couple of similar ones now and one stopped working due ( I think) to the stove getting too hot when burning anthracite!! Replaced the peltie, or whatever they're called, and it was ok but I think they're somewhat overrated as they don't move much air!! But interesting concept and a great talking point!!

These types of fans definitely work. We have a four blade on top of our wood burning stove. aimed at the opposite corner of the room where the stairs are. It certainly pushes the heat in that direction and makes a difference.

For some reason I thought this a normal fan to cool yourself down! Heat added though

They did a 4 blade 1 on Amazon aswell for a few quid more.dont know if that’s any better or worth it.

I've been using a similar one for about a year now too and its worth it. Not a massive airflow but does push the heat out a bit more in my nontechnical oppinion.

One that looks exactly the same from an ebay seller cheaper £24.95 delivered 99.9% feedback too going to give this one a go! ebay.co.uk/itm…419
Think i'll give it ago then! Only got a small room but that site says it's ideal for smaller rooms

Definitely worth the money as liamod say's it spreads the heat through your room from sitting on top of your stove dispensing heat more efficiently

Is it actually any good? Never heard or thought of this idea but if it works would be good for me

Had one like this for a year. Definitely helps spread the heat faster. I paid nearly double for one like this on eBay. If I needed another I'd buy this.
