Heat Powered Stove Fan for Wood Multi-Fuel Coal Steelhead Eco Stirling Engine

I bought this fan partly as an elegant toy and partly to circulate warm air throughout the drawing room. It does both jobs admirably. It is beautifully made and a pleasure to watch. It is not completely balanced so the blades have preferential positions, The result is that the fan requires a slightly greater stove top temperature to operate than would otherwise be the case. It is not completely silent, though not obtrusive. It seems to be quite important to ensure the stove top is completly free of dust or grit so the fan is in good contact with the stove and cannot move. Othewise it can move very slightly and make a very small noise. Perhaps a magnetic base might improve this but the magnet would have to have a high Curie temperature.

First impression : Tested it on the electric stove as it is out of season now. Before arriving my concern was the noise level.This one is not silent running but quieter than one of our old rotating electric meters so should not spoil normal conversation.Might improve later by adjusting the crankshaft assembly as rotation is somewhat out of true. May try pencil graphite lubing as well. Don't think it would be suitable while listening to classical music but for all other aural activity should not be a problem.Will try it on top of up to four 1.25KG iron dumbell disks on the large stove to further protect against temperature fluctuations and increase all that lovely roundness. Quite robust, should withstand more heat abuse than thermoelectric.

Excellent product and looks really cool sitting on top of a woodburning stove with its pistons shuttling up and down like some steam punk sculpture.

An interesting piece of engineering that looks great, works well and operates quietly. It's good as both a fan and a conversation piece.

Great item - bought for husbands birthday - he was very pleased with mechanism. No problem with delivery and came well packaged.

I bought one of these for my son for Christmas. He's sticking with it, but if it had been for my own use it would have been returned.Firstly the stove has to be really hot for it to get started, and one time it even stopped working when the stove was reduced to a lower heat output.But the real gripe is that even when it was going full bore, the amount of air flow from it was absolutely minimal, utterly ineffective at distributing heat around the room.I agree it is a nicely engineered product, so yes, it can be a talking point, but functionally it's quite useless.

so far it is performing well ,and rotates the air as it should

Beautifully made
