Stove, Updraft?

Senna

I have a boru 30w back boiler stove for well over a year now, the heat off it is brilliant and we haven't had oil since it was installed (but might get a tank now its cheaper).
I think i have an updraft problem, i cant close the stove off to allow it to simmer for long periods, even will all vents closed the flame will burn very strongly even on clam days but more so on a windy day (house is on a hill in Donegal, so rarely no wind).

Is this an updraft problem that could be solved with a suitable cowl, its just an exposed chimney pot at the moment.

If you have all the vents closed then it has to be taking air in somewhere. Is it possible the door isn't closing fully?
A common problem with Boru stoves is the door warping/handle needing an adjustment. To check, kneel down beside the stove and see if you can spot a gap in the door from as many angles as possible, it might be very minuscule.

Other than that..

Have you a cowl on the chimney at present? If so, what type?

Have you fitted a flexi flue or is it using the 8" clay liner?

Thanks for the reply. I put new rope around door and glass.
On one very windy day when all the vents were closed but the fire was roaring away, I done a smoke test with some paper to see if I could see the smoke from the paper being sucked in somewhere, but it didn't show up anything. Door and glass seem a good tight seal.

The stove is connected to an old chimney, out of the back of the stove is a 90 degree pipe that has a rubber cone on it that fitted into the flue. Is that the flexi flue?

They is no cowl at all fitted. I seen some designed for updrafts, some of downdraft but I'm unsure what I have so if you have any recommendations on what to buy, that would be brilliant.

Is the chimney claylined? (In newer house's, an 8" clay liner would be installed into a chimney as before that a house might have a big wide open chimney up to 4ft by 4ft wide.
If your house has an old wide chimney then you should have a flexible steel liner in the chimney running from the stove to the top of the chimney and this flexible steel liner should be insulated by Vermiculite Insulation beads which are poured in around the liner from above.
This liner will be the same diameter as the stove so will regulate the airflow coming from the stove as it limits the amount of air that can be pulled from the stove.

crock!

I have being at a house that has an open fire and an 8kw insert stove.the complaint was to much of a draw.i put a 6inch flexible liner onto stove because the clay pots were cracked.problem solved.on the open fire i put on a special cowl that you can see above in the link.the lady said its much much better than what it was.i have fitted 3 of them and everyone is happy with them.

Hi I have a stove door but there is something wrong , when I close my door the flame gets higher it seems like there is a pull / updraft when I open the door the flame goes down ?? I thought it when I open the door the flame should get higher and when closed it should go down ??? It is sealed all around i.e. The fire rope any help would be great someone suggested to get a cowling to reduce the pull any suggestions would be great regards Steve
