I'm interested to know if anyone has used or is using one of these wood burner fans and if they are any good or just a load of hot air.

One of my mates has one and swears by it.

Or you could get a $9 desk fan and stick it behind the fireplace. the savings would pay for its power for more than its useful lifespan.

WE have a cathedral ceiling - and my ancient desk fan is making quite a difference. We will get a ceiling fan at some point - they come with a light that the room really needs anyways - and it gets warm in the summer so useful then too - I've seen them for about $200

They are based on a peltier chip which i think is quite cool.

Based on an LPG cabinet heater we have that has an electric fan inside it, it will work really well.

It will increase the usable output of the fire place.

I like the idea of a Stirling engine fan - rather than electric:

How noisy are the sterling ones? I think that may be the mechanical ones i am thinking of.
Electrical peltier ones like what mitre 10 sells also run off the heat

I don't know how noisy they are - presumably it would depend on how well-made they were, as some loose bearings etc would make noise. I like the idea from a "steam punk" perspective. It makes wonder if a small steam turbine could be a fun project - there's certainly no problem getting a kettle on the boil on the top plate on our log-burner.

I have a log burner in my lounge and have always had trouble getting the heat down to the far end of the house. I had one of those old school cooling fans on a floor stand just lying around and I was about to throw it out a month or two ago when I had an epiphany.

I put a dining chair at the doorway to the hall, and on top of that I put a bar stool. On top of the bar stool I put the fan and, using a few bits of rope, angled it so that it was sucking hot air in from ceiling height in the lounge, and pushing it down though the doorway and along the hall.

Instant DVS system! - and the results were startling. My bedroom down the far end of the hall is now almost as warm as the lounge.

I'm now working on a more permanent and practical mounting.... everytime I have people over for dinner the DVS has to be disassembled lol

Your 'DVS' system sounds great! Very impressive, apart from the visual pollution and hazard to life and limb!

You need a few punka wallahs to shuffle the hot air around.

Make sure you come back here and show us plan B.

I just got mine yesterday. So far I am impressed, its silent, spins fast, looks nice. However it doesn't seem to push much air, yet the constant action must be beneficial. Its actually hard to tell how much air it moves, its sitting at the back of the stove so there is heat rising from the front and its trying to blow through that.

It came with a thermometer, which is really handy.

All in all I would recommend it.
