Both the fireplaces in our house were blocked up long before we got here.

However OH has drilled a large hole ( dinner plate size) in the bedroom flu
/ fireplace because a bird got trapped and was flapping around in there.

So, to the question, when he drilled through he found that the flue seemed
very small . It has been filled to its entirety with a six inch deep block.
Can someone throw any light on how a flu could be so small? Its a 1950's
build bungalow . In the country in Cornwall - so although its 1950's build
may be more akin to 1920's/30's even.

What kind of fire could have been fitted in such a small opening?

Not that we are opening it up but we have one in the study which also is
blocked and another in the kitchen which we thought once housed a boiler and
OH had considered opening one of those two and putting in solid fuel central
heating or wood burners or something, but if they are constructed like the
bedroom one, he may be stumped ( he says).

Anyone know?

6" ain't that small for a flue. Could it have been a gas fire?

Open fire place chimneys shave a "throat", ie a restriction to
controll the draught of the chimney.
Higher up you will find the chimneu will be 8" square.

Further to my prev.
To install a new anything you would need to pull all the brickwork out
until you get back to the builder's opening. ie, there will be two
piers of brickwork with a lintels/arch holding up the chimney.

It may well have to be lined. The usual way is a flexiblemetalliner
fed infrom the top.
However it's very common for these chimneys to have a "wiggle"builti
nto the brickwork a couple of feet above the fireplace..This keeps out
rain and again contols draught. This can be detected by looking up
the chimney(for daylight) when the fireplace has been removed right
back to the builders opening.

Before you decide to fit a liner, examine the exterior chimney with
binoculars.You are looking for crumbling bricks and bad pointing,
damaged/displaced flashing but most of all for vertical cracks,
(indicating lighning strikes, or more likely, a chimney fire).
This would need to be put right.
Wood burners are not as hot as coal. The problem arises fron tar
deposites which can easily catch fire and seriously damage a chimney
or even burn the house down.
This is due to wet wood, cold chimney or oversized chimney. You need a
liner for a wood burner. It will cost as much as your stove.
Wood burning is not a cheap option unless your wood is free.

Flexi liners are designed mainly as after market bodges for central
heating boilers and gas fires. NOT solid fuel fires.

An are illegal unless the property is older than IIRC 1973.

There are other systems.
There is one where they insert a long flexible balloon into the
chimney and inflate it. Refractory concrete is poured down the chimney

Problems occur when the flue bends and the inflatable "sausage"
touches the old masonry on the inside of the bend, so that when the
concrete lining is poured in it odesn't line the inside of the bend.
Doing the job "correctly" involves surveying the flue and opening up
through chimney breasts etc where the bends are and spacing the
"sausage" away from the inside of the bends - a dirty messy job which
is umpopular with home owners so often skipped by unscrupulous
installers....

Is it time for a Wiki on this?

Mine is heavy duty single wall - installed to current standards.

But that goes up a solid masonry chimney so the liner running hot is not an
issue - its primary prurpose is to prevent fume leakage and to "manage" the
updraught.

It is possible I was mistaken looking at that. The bit of offcut I saw on
mine looked like one thickness, but if the inner lining is just to smooth it
out, I may not have noticed that as it was cut with tin snips so the two
walls were probably pressed together. I was thinking "twin wall" would be
thicker somehow. I apologie for being misleading.

That is my understanding - and there's not much point anyway if a chimney is
being built as it's easier to use sectional clay liners or whatever it is
they use these days.

Exactly so.
There are flexible liners specially for woodburners, some are twin
wall.

I believe *all* solid fuel flexible flue liners are twin wall
stainless steel.

Christ and you seriously think that is actually "specially for
woodburners" ???????????
Tell me what's "special" about it?

(NB click the link and you end up on the good old "ordinary" solid
fuel flexi flue liners page....)
