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?


A small one

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?

You need about 9" to fit a proper wood buring capable liner.
