I am guessing the draught from our chimney is pretty strong and yours is non existent. 

I wonder if extending our flue would help? Does anyone know what the recommended height should be for a 5kw stove?

There are regulations on how long the flue should extend and depends on your roof line and neighbours if present.

Here it tells you to close the primary air control when wood burning. If we do that, we lose our fire - even if we wait until the operating temp has reached;

This all sounds a bit odd, there won't be a lot of smoke on a proper hot fire as it should be burnt up. Also your fire can't really be burning well with all that cold air going in the primary inlet.

 

Sounds like a bad install to me, not enough draw on the flue.

Thanks everyone for the replies so far. I am going to look into our flue height next. If we had a two storey house, the flue would have had to be much taller, and I wonder if we would have had a different result. Being in a bungalow means a lower flue than a conventional house....

A good draw also depends on the flue top being higher than the ridge of your roof and also higher than close surrounding buildings.

What diameter is the flue passage  in the chimney and is the register plate well sealed where the flue enters the chimney?

Reading the recent answers - it sounds like you are running the stove well and as you can see, thinking about the installation. Has it always done this? If it is intermittent are there weather conditions that make it worse (noting that we had quite a windy weekend, and then you asked the question....)

 

Chimney height shouldn't make much difference - you get them on narrow boats with a much shorter chimney, but clearance from things around it does (air vortexes and stuff).

 

One thing that came up a few months ago but not applicable here is if you have the room doors shut there night be enough draughts to allow the fire to burn but it is working hard to suck the air in - if the room is sealed, the right weather then the pressure differential can b a problem. So last question for now, do you keep the room door shut?

Im not up on these terms, please excuse my ignorance. We don't have a chimney on our bungalow, i think they called the flue they installed, a twin wall system?

Pretty much yes.

The lounge door is always open to a large hall and open plan kitchen/diner. There is also a vent in the exterior wall of the lounge, presumably left over from the gas fire that was there previously. We can feel a draught through it, so theres plenty of air coming in.
