heat resistant gaffer tape?

[Dick_Turpin_99]

Not sure if this is the right place to post this but the space heater in my workshop lets the water in down the chimney, we have put a cap on the top to keep the worst of it off and I am of the opinion that it is in fact coming in through the joints fof which there are 3 outside.

So plan 'a' is to take it down and put hylomar (blue instant gasket) in the joints, but it comes to my mind that it would be a lot easier if there was something like gaffer tape but heat resistant which i could wrap round the joints instead. Is there such a thing?

You need heat resistant duct tape, http://www.amazon.co.uk/Aluminium-Heat-Proof-Duct-metres/dp/B004X5U8HS

If the (slip) joints are letting water in have they been put on upside down? Tape is only a temp fix, the heat, sun, rain will take its toll eventually.
They usually leak at the junction with the roofing sheet.

they are "upside-down" to stop the tar washing down the outside, we thought it was wrong but thats the way the kit came and the way the installer advised it should be.

the water is running down the inside of the pipe and the angle through the side is a 45 deg angle with one of them rubber flashing things around it with the joints either side.

They did gob a little smear of loctite around the joints and at the time i didn't think too much of it, then when it started leaking i thought it was coming in from the top, only after we put the cap on it and we had steady rain (with no winds) did we see it still leaked which made me thing of the joints

You lost me there, can you explain better? What is someone doing washing tar down your chimbley and won't this run in an upside down joint just the same as water will?

Silicone sealant is another bodge you could consider, it's quite high temp resistant.

or exhaust muffler tape

sorry the pipes fit together with the top outside fitting inside the lower one, making a funnel effect.....now the gadgys that put it all up there said that if it was the other way round top fits outside the lower one that the tar on the inside would run down and out the joints making a mess of the pipe ...... at the moment I am thinking i would rather have a dirty pipe rather than water in the workshop......but having said that it wouldn't fit the other way round (joint to boiler and the baffle thing at the top)

I would have said that this was wrong. Is there actually 'tar' running out of the joints as he predicted?
What is usually done is a T piece at the bottom so the fumes can go in and up the pipe, but anything running back down misses the heater and drops into the bottom of the T.

If you burn soft wood, and over load the fire, unburnt smoke carrying Tar will be carried up the flue, condensing on the flue wall, running down.

Have yo tried High temp silicone

its a space heater isnt it not a wood burner

 

[Shox Dr]

So where is the tar potentially coming from? it must be capable of burning coal/wood etc

this thing burns old oil or any derivative of it. i'm no expert on this kind of thing but the jesters that stuck it up there do this and household boilers for a living, so their reasoning seemed a good idea to me - at the time.

i'd like to take a section out because the wind fairly howls up the valley and catches it, the bumpf that came with says about 2 metres above the apex, i'm tempted to which off the top bit, there's already 4.5m inside......and it would be one less joint to leak

kinell i thought it was an orange aerial mast supprised the wind hasnt knocked it down surely it doesnt need to be that high

yes, its got a lean on it now after the winter storms!!!.....even more reason to take a piece out

The Titanic had smaller chimneys.

There's probably a building reg or something about minimum height of outlet above highest roof point?

there is and its not that height

they reckon it was to get enough 'draw' on the burner

 

[brightspark]

the recomended height is 1m above the ridge on a waste oil burner

Out of interest what burner do you have? Also how big is your workshop and is it insulated at all? I've been looking at these,

But not sure if it will heat the workshop as its around 2000 m/3 and has no insulate I don't know if it would make any difference at all.
