Extracting hot air 2.5 m

When the chocolate cabinet is turned on it generates a lot of heat.
This is obviously counter productive in making things cool.
My plan this year is to fix a bathroom extractor to the output side of the motor to take the hot air away from the chocolates.
How powerful a motor would I need to move air 2.5 m?
With that distance would I need a fan at the motor end and one at the vent end?
Can't really fit it all in the picture but the hose would go under the counter.

You need a heat pump, then you could capture the heat and use it for heating water?

Not very powerful. Our bathroom extractor fan duct length is about that, and you can see it pulling steam out of the shower cubicle it's mounted in.

It's just one of these cheapy ones too, with not too much more expense you can get something that looks a lot more beefy.

I have one similar to this. Its great and a lot more flexible than a bathroom type as you can duct it each end so put the unit where most convenient

A basic extractor fan will do it, if the exhaust route is straight, 110mm soil pipe or similar will be better than the corrugated stuff.

Bare in mind if the wind is blowing into the outlet, you might prevent it exhausting effectively and overheat the cabinet.  You can get an inline flap to stop wind blowing the wrong way but wind may hold it shut.

Can you get a remote compressor kit for the cabinet? That would mean you could house it in another room and just run the coolant lines under the counter.

Is there a solution that involves an extractor that uses a 3 pin plug?

@zippykona I have an extractor fan in the garage (I think) that I'll send you for the cost of postage.

Put a door on it!

EDIT: it seems you have. In that case it's working no harder than any other fridge.
