759429 2009-03-26 04:37:00 As pcteck says, newly manufactured solid fuel fires can not be turned down or "banked" to burn overnight as this is when they produce the most pollution due to incomplete combustion, rny (6943)
759430 2009-03-26 05:12:00 Coal is vile disgusting filthy polluting stuff.
It should be banned.

I was talking over 25 years ago when it was then a very popular thing to burn.
Our company were also wood and coal merchants and we had two trucks almost working 6 days a week to keep up delivery supply.

Getting it off rail, Bagging it, and delivering it was hard and dirty work.

Now they do none at all.

But even so there is no way you can get as much heat from a wood fire even if your burning hardwoods.

759431 2009-03-26 19:53:00 I've got my multifuel stove connected at last burning well dried timber.
In theory I should be able to close the air supply so it just ticks over but it blazes away and there's no way a full firebox will last overnight.
The agent and the installer aren't being very helpful.
I'm wondering if the stove pipe and cowl are causing too much updraft...I live on Windy Wellington's south coast.
Does anyone know if there are cowls which restict the updraft rather than just prevent downdraft?

It is the amount of air getting into the fire box that is the problem.
As other people have said, this is to prevent the fire being"closed down" to a smoulder and thus producing unburnt particles (smoke) and so defeating the purpose of a clean fire.
If you are mechanicaly adept, you should be able to modify the air regulator slide stop, so it closes a little further. This will give a slower burn rather than the regulated lowest burn you have at the moment. Your call of course and be aware of warranty implications.

This is the stove

Because its "multi-fuel" not just wood burning it doesn't have to comply with the smoke emissions regs.
The manufacturers assure me that it should be capable of very slow burning (overnight if wanted). But I can't get it to slow burn during the day... I'm having to put in more wood every couple of hours... that includes slower burning wood like manuka and gum.
There are 2 air controls, one on the firebox door and one above. The first is pretty tight fitting, the scond seems a bit slack. I can only assume that too much air is getting in, either through the air controls or maybe a faulty door seal. There's a hefty updraught as well so that's why Iwondered in my initial posting if there is some sort of restricting cowl that could be fitted... I don't think I can reduce the chimney height without falling foul of the current building regs.
