Chimney fire

[Peasgood]

Buy a brush and do it yourself

Costs about the same as paying a sweep, free after that.

Can't say I would want to have my chimney on fire for the sake of not paying a sweep anyway.

if it a flexe liner you have to be very carefull as they are easy to damage

When I was in the fire service. We used to use a stirup pump with a hose on so only used the bear minimal water to put the fire out.

You put the pumpkin a bucket of water and sent the 360 degree spray head up the chimney giving the pump a few strokes every so meters.

Check chimney breast with thermal image camera.

 

It was not too messy a job unless it all started going pear shaped.

Chimney fire knowledge must have come on a bit Hazzy, that would be the most effective way.

It was a while ago I saw them just unleash a hose straight down the chimney of a neighbour.

Dousing red hot brickwork with freezing cold water would have caused more damage to the chimney than the fire.

so dad and went up damped it down with buckets of water,

 

Genuine question - What happens to a metal stove if you drop buckets of cold water down the chimney? Presumably it can't be good?

 

Or would the heat from the chimney fire reduce the impact?

 

Just wondering for future reference - although my flue is lined.

Noticed a few days ok my chimney pot was cracked. By all accounts if the crack spirals round the pot from the base, likelihood is you've had a chimney fire. So my mate who's a roofer popped up there and said there was lots of crispy tar etc round the top of the pot, so we had probably had a fire without noticing. Anyway, swept the chimney straight away and only about half a cornflake bowl of soot came out, and that was after a really good sweep so how does the fire bit work, clean chimney and still a fire??

Creosote from logs can form a hard glazed layer as it's deposited. It won't shift with a brush. Highly flammable yet a sweep will produce little soot which can give a false sense of security.

I suppose there is the question - if a chimney fire is well controlled in a lined flue, is it really an issue? A useful (lazy?) alternative to sweeping your chimney!

 

Nope...as long as you can control the burn. IMO it's the only way to properly remove the tar deposits

Can't do those flexible liners much good though can it?

The temperatures at the base of the liner must get very high, at a guess I would say a controlled burn of tar wouldn,t be as high a temperature. If it was left with no air restriction, I would imagine the temperature would rocket, if you have ever heard a full on unrestricted burn, it is quite scarey, it sounds like a planes turbine engine winding up
