chimney should be lined with a steel liner.

Quite right:  forgot that bit.

Littlegem,

That really was a big gem:  air-con is the way to go ;D
We've looked into heatpumps:  for 1kw of electricity it can transfer 3kw of heat from outside at 0C to the inside at 23C:  that's wonderful.

You could get that 1kw for nothing!!
