Thedreamer Posted November 29, 2019 Share Posted November 29, 2019 For those of us, who like a bit of ? in our lives, who's purchased a stove fan, worth splashing £30? 1 Link to comment Share on other sites More sharing options...
BotusBuild Posted November 29, 2019 Share Posted November 29, 2019 Only if the stove is in an alcove. If its out in the open, let convection do its thing Link to comment Share on other sites More sharing options...

SteamyTea Posted November 29, 2019 Share Posted November 29, 2019 Are these those fans that use the heat from the stove to turn s small fan? I have often wondered how much energy can be moved with them. Quick Google and you can get them from Aldi for less. Link to comment Share on other sites More sharing options...
Ralph Posted November 29, 2019 Share Posted November 29, 2019 I found it difficult to tell, could have just been the placebo of having spent some cash on it. 1 Link to comment Share on other sites More sharing options...

Heard on You & Yours some marketing person talking about 'emotional mechanics' today. That should cover any effect nicely. Link to comment Share on other sites More sharing options...

Whilst they could no doubt be built based on a Stirling engine, that would take some half decent engineering. Most of them are simply a little peltier effect generator driving a small dc motor. The "fins" on the top are to try and cool the upper half to maintain a temperature difference between that and the bottom part heated by the stove.

Cpd Posted November 29, 2019 Share Posted November 29, 2019 I have been using one for 6 years, it was quite expensive but I went on the reviews and it’s been working great, as I live In An uninsulated house the fire is on a lot during winter and this fan has raked up thousands of hours ! I am sure cheeper ones are great but I prefer to spend my cash once and not be disappointed by a noisy fan or failing parts. I have recommended this one to friends who have not complained at all. If you have a big high ceiling then an overhead fan is very good at moving the air around. Link to comment Share on other sites More sharing options...
Tennentslager Posted November 29, 2019 Share Posted November 29, 2019 None of them are pretty are they? ive got one but can’t say I notice much difference but it was £30. good witchcraft though-no batteries visible at all, reckon it’s like a watch battery hidden somewhere you can’t find. If you paint one of the fan blades white and get stoned on the teenagers green, it can be a talking-point when the conversation dries up... 2 Link to comment Share on other sites More sharing options...
SteamyTea Posted November 29, 2019 Share Posted November 29, 2019 I just had a quick look at a small domestic wind turbine. This little 1 kW jobby needs a rotor diameter of 1.8m and a wind speed of 12.5 m.s-1 (28 MPH) https://futurenergy.co.uk/domestic-wind-turbines/airforce1/ I would be dubious that they can deliver more than a few watts about. 1 Link to comment Share on other sites More sharing options...

You can buy something similar sized on ebay from China for a couple of £hundred. At that price I might one day take a punt more for fun than real expectation of significant generation. A bit like micro hydro from our burn that will probably only produce 100W so would need to be REALLY cheap. Link to comment Share on other sites More sharing options...

That's what I meant. Similar to the one I bought my lad that you can sit atop a cup of tea. Link to comment Share on other sites More sharing options...
