- Eco fans for wood burners – first impressions
I bought one of the fifty quid jobs from amazon, with the thought in mind that I’d probably be utilising the distance selling regs and sending it back as I reckoned it either wouldn’t fit in the space above my stove, and I’m a bit skeptical too.
Very, very impressed! (Yes, it fits – just) the difference is quite incredible, from the point of view of how quickly the room heats. I can’t say if it will be any warmer or not, as it’s only been on an hour, time will tell with that one. I’m in an old house with pretty high ceilings, so it makes sense that the stove had to fill that space first before the heat comes down to sofa level, not any more though.
I don’t think it’ll be going back.
Edit – it’s silent too!.Posted 4 years agoWillHMember
Do you need to have a ‘solid’ top to your wood burner, i.e. a thick cast-iron top or similar? We have one of these:
which has a grille top which sits about 2″ above the top of the fire box. I’m guessing it’s to keep the surface temp down a bit (although that would perhaps defeat the object slightly…). Anyway, this grille gets just about too hot to touch, but I’ve never measured the temp. Would an eco-fan work with this type of wood burner?
Also, it’s almost summer in this neck of the woods so it’ll be six months before we use it next, so can’t check operating temp for a while…Posted 4 years agoStonerSubscriber
WillH – I dont think it would work on yours.
The fan base conducts heat to the lower face of the Peltier device. Your grill will be too insulated from the ehat source to conduct sufficient heat to maintain a high enough current through the fan motor.
A colleague has a fan that he bought for one of his two stoves. Before he installed the second stove (with a proper metal plate top) he tried it on his other stove that has large sandstone heat-sink slabs on the top and whilst the fan ran, the RPM was quite low because of the lower heat transfer. With low RPM, the draw of cooler air through the upper heat sink fins of the fan body is less and so the heat differential across the two faces of the peltier is lower, his leads to the current dropping and obviously the fan slowing down further, meaning that you get into a cycle of lower fan performance until it barely turns.

my fire is a backboiler so never gets hot enough to boil a kettle,
15kw backboiler feeding the CH, two hot plates and an oven, one of the hot plates gets plenty hot enough to boil a kettle (about as quick as the 1.5kw rings on our cooker)
maybe you just need to use more fuel?Posted 4 years ago
its a la nordica termosuprema – they (la nordica) do several similar kitchen ranges without backboilers http://www.lanordica-extraflame.com
I believe broseley sell them in this country – not sure if they do the whole range.
as wood fired ranges go, its quite good, build quality is excellent and the stat moderates the fire quite well (at least, when fed nice dry wood)Posted 4 years ago
We don’t have a chimney breast, so stove is “freestanding” in sitting room. Anyone else have this set up and get an improvement from a stove fan?
Yup – got the same fan as Nobeerinthefridge several weeks ago!
It has made a tremendous difference to circulation with the loving room in which it is situated and the house as a whole. Project Management commented on the difference it made as soon as she walked in the living room the day it arrived – and she is, erm, ‘skeptical’ at the best of times…Posted 4 years ago
Cheers mrmonkfinger – will have a look . Got a chimney breast in the kitchen- stove is going in without question …. Something a decent height we can cook on when its lit would be a bonus. We get frequent power cuts opup here – not often as long as last weeks mind you.
Omitn – look at the ecofan website – there is a simulataion model of how it distributes air better on there .Posted 4 years ago

no worries. ours is standard worksurface height & depth, about 1m wide. its linked to pumped CH – so we can’t really run it full blast for very long if the power is off. Although we can raise the firebed (less energy to water) and redirect the gasses preferentially toward the oven (even less energy to water) that still results in the CH getting fed heat every so often.
The problem is it has has a saddle design so the top of the stove always has running water through i
