Stove fan

[woodwizzard]

Can stove fans be used on stoves with a canopy on top? I have a villager chelsea that has a high top canopy, I know it gets hot, but do canopies get hot enough?

Probably not. 

 

I've gone off stove fans to be honest. I always used to have them on my old stove back in Scotland. One of the issues is that over time they slow down. What has been most apparent with the new stove is that they move very little air. We have a double sided stove at the new house and the stove fan on top did nothing to push the hot air into the living room. A small electric fan mounted on the fire guard on the other side (running at 17w) moves many many times the air of a stove fan.

 

If your set up allows, perhaps a high temperature duct fan mounted in the recess for the stove would be more effective.

Our stove is only 5kw and stands out in the room. It's probably a question I should've asked before purchase, but can always send it back. It is going around, but not with any speed. Giving something for the dog to stare at, but that's about it.

 

Just lifted the canopy off and put the fan on the stove top and it's spinning like mad now.

They just don't move much air and the peltier module wears out over (a fairly short) time. I've had several stove fans and they at best serve as a visual indication of how hot the stove is. I have a thermometer for that though.

 

As I said, what brought into sharp focus how little air they move is having a tiny fan of just 17w move many many times more air than the stove fan.

Yup im goin off stove fans.... thought i’d killed mine. It gave up for a good long while. Now and again decided to come alive. Think i’ve cooked it to be honest.

 

Dont think i’ll bother with another one

 

mine was a decent eco fan too

Just put the canopy back on and it's almost stopped. Oh-well, will see if I can return it.

 

So there you have it, if you have a high top canopy on your stove, don't get a fan!

You cant put a normal fan on top of the chelsea canopy even if there is enough room, two reasons,.  A,  The Chelsea canopy is an add on unlike some older Charnwoods etc where the inside of the canopy is part of the inside of the stove.   As such is not get hot enough to drive the fan properly.    

 

B,  The fan needs to sit right on the back of the stove as it needs cool air coming up the back of the stove to keep the motor cool,  that is likely to be restricted at best or non existant at worse with a canopy.   

 

You CAN get a cool top stove fan for use with gas and cylinder type stoves where the tops are only half as hot as the sides,  this is though getting on towards £200,  but it still needs the cool air flow.

Someone else mentioned a fan stopping and starting,   I only sell Ecofans so cant speak for the rest,  the usual problem with them is people knock them off the stove and bend the motor shaft.  In that situation a new motor resolves the issue.  But they dont stop and start,  you bend the shaft and its all stop period.

often it just needs some fresh thermal conducting goo on the peltier to fn base bond.  cost for the goo is just a quid or 2.

I had a sloping canopy on an old woodburner (also possibly a Villager of some sort) and I managed to make a stove fan work fine on it, at an angle, supported by bits of string! But that was an ancient stove and the canopy got nice and hot...

Sounds like the canopy was part of the firebox,  Charnwood, Yeoman and a few others made them like that in the past.
