Thread: Heads up on something I found

I was looking on ebay for chimney cleaning brushes and I found this item, haven't seen any of these for many years but I know they work very well. Too well if you do not burn dry clean wood. I am including the link si any-one contemplating a free standing wood fire can see.

5" Enameled BLACK Ribbed flue-increasing heat output - wood heater/ oven/ stove | eBay

Hey Moondog, nice find...
Trying to see where I can get one of these to fit in my house.
We just managed to source a Metters no2 stove, freestanding, for our kitchen..to go with our gas stove/oven, but cannot get one of these in as the flue outlet on the stove is oval, bugger, looks like they actually might work...maybe I can get onto our woodheater...could be seen as a bit ugly by some though.
So, how did you go in the chimney brush hunt? Something I keep saying I have to find, but never quite get to do...

Same seller has 150mm brushes and poles. CC does not want me climbing tall ladders tho, worried about me falling off and bruising myself.
Shame those heat exchangers are only in 5 inch.

Looks interesting. Good slow combustion stoves burning good wood don't have much air going in so not a lot of heat loss. Don't want to cool outlet air so much that there is condensation of creosote (contains poisonous phenol) inside or dripping off the cap onto the rainwater collecting roof! Also, when stove is idling there is soot build up in flue which might accumulate on top of that manifold when it falls down as fire is revved up. Could be extra cleaning required.

Actually good slow combustion stoves have lots of air going in and not too much heat going up the chimney! Good designs that exceed current Oz standard use multiple combustion chamber designs (usually 2-stage now in Oz with a primary and secondary air input for combustion - some EU designs have 3).

and
Always burning dry, untreated wood with a moisture content less than 20%.
Ensure that the woodheater you purchase complies with the current Australian/New Zealand Standards AS/NZS 4012/4013 to ensure maximum efficiency emissions controls (AHHA) - ie: newer than 1992.
Get a hot fire going quickly. Keep the air controls set high enough to keep your fire burning brightly.
Don’t overload your wood heater with firewood.
Never leave a wood heater to smoulder overnight. Doing this starves the fire of oxygen, producing more smoke and air pollution.
