Stoves

[renewablejohn]

Problem A solved. Problem B is getting a 200kg stove from the back of the jeep and into the house. I'll leave problem C until you are all more agreeable.

If you where nearer you could borrow my industrial rollers. each can cope with 20 tonnes so 200kg is easy.I an sure a local engineer will have suitable rollers and steel plate. Ice bricks in the freezer are handy when you get to the final position to get your crow bars out.

Well, my stove was made by a well known company and was installed by myself (with the full approval of the local building inspector) but the flue was connected by an (allegedly) HETAS certified installer. It has been moderately successful except that it smokes. Very very badly in a strong wind. There's currently a 25mph wind blowing and to avoid being smoked like a kipper, I have had to have all the windows open. It smokes in conditions like this whether the vents are opened or closed and after the flue has warmed up.
W.what you jeed is a wind cat for the top of your flue
So what's the answer? The chimney was swept the other day, the draught tested as satisfacory, and the stove has been smoke tested -- all apparently satisfactory.

It has a cowel but I suspect I need a special one to prevent down draught? But where can I get qualified advice (which probably means not local)? I am in the Scottish Highlands.

Sounds like you need a H chimney pot fitting.

A windcat from germany will solve the problem

A young lad and an auld lad carried it after removing as many parts as possible.

I am off to Google! Thanks.

Found it. I'm impressed. That should work. I was thinking of a rotating cowel but it is pretty obvious that they would fail sooner or later due to clogging with tar or wear.

Off loaded mine with the tractor loader, then wheeled it inside on rollers made out of 12" sections of scaffolding pipe kept for similar jobs.

I read something before, I think on here, someone described fitting some sort of cowl or hat on their chimney and the dust sheet they had covering the ope during the work was sucked up the flue as soon as they put it on.

I want one! I want one!

Most stoves are DEFRA approved in the uk these days. All is seems to mean is you can’t shut them right down fully so they burn ‘cleaner’
If you want the stove to burn through the night I’d say get a non DEFRA one. Probably a bit more damaging to the environment but will give you greater flexibility

Resurrecting this thread, as mentioned above, my problem is smoke coming back down the flue. Sorry if I'm hijacking, but the thread does seem to have died!

There was a 25mph east wind the other day and the smoke coming out of the stove was horrific! The flue has been swept and I am discussing options with the stove manufacturers, even though the stove has now been cleared of blame. The problem does seem to be downdraft as the stove smokes when there is a strong wind even with windows open. On the other hand, yesterday was dead calm, no wind, and the stove behaved almost perfectly.

Someone suggested a Windkat cowl and from what I've read, they are very very good but also very very expensive at around £300 (taking delivery to the Highlands and labour costs into it). Another suggestion has been a simple cowl designed to combat down draft at around £60 plus fitting. Coiuld it be that simple? Then again, a Dragon cowl (£150?) -- but that rotates and I'm reluctant to fit anything with moving parts that might rust or tar up and stop working.

Anyone had similar problems? And if you solved it, how did you do it? BTW, I'm told piping in an air supply from outside can also create negative pressure inside the building if the wind is blowing across the inlet (venturi effect?). I never seemed to have this problem with the old stove discharging smoke directly into the original masonry chimney!

All i know is strong my wind better mine draw

Whats local topography, i top of stack clear of ridge hight of house ...

Makes no odds imo , it's how much air come in .

 

[tomlad]

How do u mean, comes in which end

 

[bobk]

Well , it's better if air comes in at the bottom .

The chimney is actually at the east end of the house so well above the ridge. I have tall trees to the west of the house and I think that affects the pressure to the east when the wind comes from the east, though I would have thought the opposite. Aerodynamics is not my strong point! Fire working perfectly this evening, but virtually no wind.

 

[bobk]

What happens to your car if you restrict air intake ?

 

[Dry Rot]

Here's a rough sketch of the layout. The house is pretty much east-west withthe ridge paralle to the wind. Stove (obviously!) inside against the east gable wall. There's a window to the south of the stove and anotjer in the hall that I have to open to let the smoke out. If it's windy, it doesn't seem to have much affect on the stove, the smoke still belches out!

 

[tomlad]

So the airs not going over the trees, instead pushing down ur flu ,??

How many trees , chop them down ?
