The fire is missing....

Hehe.... you bunch of dirty pervs! 

Well, anyway, Mrs. R is talking about diaphragms now, so I guess the thread has heated up a little!    The fireplace screen with inset candles looks amazing, and I plan to put some vases with flower arrangements on each side to enhance the romance - making sure the fire stays in where it belongs! 

I don't like the electric fires - I can always hear the fans in them.

The ones I had in mind were simple radiant, or combination radiant/convector models, no fans involved at all.  Like this:

(The ad is just a few years old, so don't expect those prices for equivalent models  today!  )

However, I have heard that due to the age of our house, and the uncertain condition of the internal brickwork/stonework of the chimney, we really ought to get something called a chimney diaphragm (I think it's called that? it's like a metal tube to line the inside of the chimney, so as to prevent fires) but I've heard they aren't cheap. 

The term you're looking for is chimney liner or flue liner.

Ha ha - well.  Thanks.  I was describing the thing to someone today, and they called it a diaphragm, so I thought - well ok, maybe that's the term for it.
