woodburning / multi fuel burning stove

I'm considering having a stove fitted in my living room. The main reason is due to the ugliness of the present bricked up chimney opening.

I've had a quote for the work which includes everything apart from supply of the stove.

I wanted to do a bit of research before proceeding though.

The current chimney breast opening is ugly and asymmetrical so I see my options as removing the breast or opening up the fireplace to produce something more aesthetically pleasing.

A friend suggested that doing so could make the room colder as most of the heat would disappear up the chimney. Is this true?

Is there no way to get a nice symmetrical, smooth finished opening with the chimney capped off if we don't fit a stove or the chimney sealed to the stove if we do fit one?

I don't want a situation where opening up the chimney necessitates having the stove on in order to combat the heat being lost up the chimney!

I also wanted some pointers on what I can burn given that I live in London?

Finally, what are the metrics used to identify an efficient stove. I don't want to get something that is hideously inefficient that makes me regret embarking on the whole enterprise.

Many thanks

Ideally, get the chimney lined with the appropriate size twin wall flexible liner. This must also include a register plate through which the first length of stove pipe protrudes. This is sealed to the chimney void with an intumescent sealant.
I make register plates (3mm mild steel) with a door so any debris that comes down the chimney between the liner and chimney can be vacuumed away.
With the stove dampers closed, there will be minimal air flow up the chimney.
Consider a brand of stove that takes its combustion air from a pipe outside, and you’ll not notice any air flow through the room when the stove is lit.
Stoves of 5kW or less don’t need external vents, bigger ones do.
Research eco fans - which are surprisingly good.
You may be surprised how much fuel you’ll use...up here it’s dry hardwood and carbon ovoids which are approved.
