Controlling multifuel stove.

[martynz]

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?

There should be a damper in the flue which needs to be almost closed for burning at low level overnight as well as shutting off air to front of the fire.

Sounds to me as though the the input air control or damper is just not working. The fire should be able to be turned right down so that flames go out.
If not get back to the suppliers and say it isn't working properly.

On our Garth double burning wood fire built into the fireplace, and which admittedly is old now, some 25 years or so, there is no flue damper. There is just the air input control which works well.

However it is not a good idea at all to run these fires overnight at low air settings. The wood is not going to burn properly, smoke will be generated, and the flu will coke up more quickly, especially with resinous woods like pine.

Edit: maybe new wood burning stoves are made not to be turned down, for the very reason to prevent smoky slow burning ?????????

Ours won't last all night either. Most won't. Because they changed them so you can't turn them down as much as you used to be able to. To make it "clean air" compliant.

For all night burning try the really old, well seasoned, senior wood. Available in many places and commonly called coal.

Yah cant throw coal ash on ya garden.

Throw it on the neighbour's garden.

When we lived in Green Island we had a Yunka fitted. It would burn coal or wood. It was never a problem having coal burn away all night when closing it down.

We used to run a Mix of West Coast Coal and Mataura coal, both very hot burning coals. Twice before it was out of warranty it burned all the enamel paint off the first section of chimney and we had it replaced. They never did figure out why it was burning the paint off.

Just Hot coal and wide open on cool nights.

Coal is vile disgusting filthy polluting stuff.
It should be banned.

But we can turn coal into nice clean electricity.
