Several years down the line I am looking again at installing a small wood
burning stove in the Mother of All Sheds.

The fireplace area is all there as planned. The flue will go up through
the tin roof. As there is 375mm between the rafters I think I will need
twin wall stainless for that area for fire safety. I may get away with a
5" flue.

Now the main issue - running the electrics.

I could run the wiring along the front of the shed but this will pass the
flue. Is there any guidance about how far horizontally wiring should be
from a single walled flue? In trunking (probably plastic) along a ceiling?

For the wiring to be easy and unobtrusive it would be best to run along
the front or back walls. However the front wall has the stove, and the
back wall is where the toilet and shower are planned.

I am guessing that trunking through a shower area is not optimal - it
would have to be an electric shower so I assume that I have to have some
method of concealing the electrics anyway to emerge behind the shower, so
perhaps I need a false wall to the shower with all the cabling behind.

The other alternative, I suppose, is to run the trunking down the middle
of the shed end to end. Not very pretty and it would have to be shallow
because of the head room. I suppose that at just under 2.2 metres there is
adequate clearance for most. It would have to carry lighting and at least
one 13 amp ring main (or perhaps a couple of spurs).

Internally the shed is roughly 7.6 metres long and 3.3 meters wide. This
should be plenty of space but it looks to be full at the moment!

If I manage to fit a toilet and shower along the back wall to turn it into
an office/studio/garden room then it will start to look a little bit snug.

Cheers

You will need a twin wall flue and it'll cost a much as the stove.
I nailed/wrapped aluminium sheet round the the rafters adjacent to the flue and filled the space with mineral wool.

You can buy flat stainless steel plates that fit round the flue on the underside of the roof. On the outside there are various weather proofing devices.

Why not out through the wall, then up?

And get it done in two years as the pollution police have their eyes set on
wood burners now.

Mainly because I have built a double thickness wall where the stove goes.
Although this just requires a deeper hole cutting.

Also for aesthetic purpose, and because a block paving path runs across
the front of the shed and a flue pipe would obstruct that.

I think I will have to go dual skin stainless for the above roof part, so
extending down from the roof to just below the ceiling won't cost that
much more.

Dual skin stainless to keep the flue temperatures high enough to avoid too
much condensation and tar build up.

Starting again I might consider locating the stove elsewhere in the shed,
but front and centre still seems the most logical place as it shares the
front wall with two windows and two double doors, leaving all the other
walls free to have stuff fixed to them.

Overall design is to allow it to be split into two; garden room at one end
and tool store/workshop at the other. Hence the two sets of doors.

Once I get the crap moved, tidied or ditched then I will be able to have a
better run at internal layout.

Finishing off the mains water and drainage will be an achievement long
overdue.

Cheers

It is essential to install an air inlet vent aadjacent to the fire or
you will need a door or window open.

Some stoves can have an air supply connection option direct to the
fire box . That means you are drawing air from outside rather than
drawing in warm air from the space you want too keep warm.
A pipe from outside under the floor terminating in a drain grid under*
the stove is another way of getting very close to that for stoves that
don't have the option.
Both methods alleviate the problem of a stove producing a cold
draught at ankle level as draws in fresh air from outside which can
sometimes occur due to stove position though it sounds like it won't
happen this case.

Legally if the stove is 5 kW and the shed is not classed as new
build and is not completely airtight a vent isn't required but unless
putting one in is a right pain it is still good practice.
Intersting site on the subject here
http://www.stovefittersmanual.co.uk/...burning-stove/

What has been required for a couple of years now is a carbon monoxide
detector.
This assumes the OP wants or needs to comply with the regs, as it is a
"shed" some people may take a more relaxed approach depending on the
circumstances.

* It actually hasn't got be under, but not where ash etc falls in it
when you clean the stove which means one just in front needs cleaning
out more often.

Building regs (I think) applies a "300mm/foot" rule between hot surfaces
(stove hot) and combustible materials. It's a good metric even if I'm
wrong about it being in the building regs.

After that, you are into IET regs land - which merely says that the
cable and it's load should be designed and installed for its environment.

eg PVC cable could run upto 70C with sod all load (eg a light).

Power, you will have to look at the derating tables vs breaker trip
current vs cable CSA (mm2).

If your shed is wooden, I would consider an insulated flue stack - this
will help with your cabling too...

you will need a door or window open.

Hearth has two air bricks installed to the outside which will be directly
behind the location for the stove (specifically to allow fresh air to be
drawn directly into the stove from underneath behind).

Stove is also less than 5 kw.
