Wood stove fans

[johnnyb]

Just a warning if you've got a particularly efficient stove it will knacker the plate if it gets to hot. Some have a bi metal plate to lift it if it overheats. I just stick a bit of tile underneath....

I have two on top of my stove. set into an alcove. One cost over £30 a few years ago and the second was from Aldi about £16. They do create a small draught and help move air around the room. The Aldi one is the better of the two. I am happy with mine and would replace them if/when they die.

The dust with a stove/fire is inevitable although i have not experienced a room sealed one.

It's not so much the plate as the peltier device that generates the lecticity to power the fan: it's very fragile especially with regard to over temperature.

Just substitute plate for device in your sentence.

Reading this thread and seeing the wildly differing experiences/ opinions I wonder if there could be differences in the efficiencies of the various fans, sure they will all spin round, probably at similer speeds, but I wonder if say the pitch of the blades would make a diffence?

Yep - everything makes a difference (disc rotation speed, blade disc diameter, blade area and area shape, number of blades, cross-sectional profile of blades, average pitch of blades, etc...) - and each of those features are interdependent. It just means that you just have to "trust" that the design of your chosen product is functional enough. Each of them will have gone through prototyping, testing and development - to varying degrees. So will at least work to a varying degree or other...

For me (even though I know very much about aerodynamics and thermodynamics) I don't really place much worry or stress into choosing one of these. They work fine. Some will work "better" than others. But equally, for me at least, the design element is also a valid purchase consideration. For me, there's no point investing in the "most efficient" aerodynamic/engineering solution if it is an ugly contraption.

If you install, use, a room air purifier/filter you'll find the dust levels (if an issue) will resolve much of that. I have a Levoit 300s in my lounge - 15x25 ft...; works a treat. Can't say dust is much of an issue now - if at all. Check it out on the big river company site... I have similar in my bedroom and it work equally well at keeping down airborne particles of whatever type; and in sleep/auto modes is well nigh silent. A 400S serves the main house - it's in the hall, though I may mover it to top of the stairs to see what effect that has. Again it's sleep/auto modes darn near silent. They all up the anti to hgher settings if/when they detect anything inappropriate; some. dust, and smells and so on and gradually drop down the setting you lefet them on when all is clear.

This the stove fan I have (2 of)

COMBIUBIU 4 Blade Mini Stove Fan​

That should sort it, no need for a fan (from my fb feed).

Great idea... But do really you drink that much tea/coffee in a day...?

I had an electric fan blowing across the front of the stove in along room, and a 4" fan just below the coving at the other end of the room blowing out into the stair well. In the winter when both fans had been on for while the difference upstairs was noticeable, had I stayed in the house I'd have changed the 4" fan for a 6" one. It doesn't really apply now as I have an insulated 6" duct running from the ceiling above the stove to an inline fan and a Y piece taking the excess heat down into the other side of the bedroom and kitchen

This is very interesting to me!

The biggest frustration I have with using my wood burner is that I’m not utilising the heat out to the rest of the house (extended bungalow so quite spread)

When it was installed I did have a bit of a chat about getting a boiler stove, thinking that if I could at least have a few extra radiators added that it would benefit everywhere else. The installer wasn’t keen so we carried on as standard.

I’ve wondered a few times about ducting. Also about a central mvhr.

Can I ask for more details on your ducting system please?

Did you install it yourself?

Do you think the fan is essential or could it work passively?

Are there any issues with it such as noise from room to room?

How about compartmentation / fire risk? Is it building control approved (not that it would necessarily stop me)

Thanks!
