In a previous life I had two wood burning stoves (one clearview, - far
superior to the other, a morso) and and endless supply of cheap wood
with plenty of space to store.

Since moving I need a heat source in my living room to replace the
useless "living flame " fire.

I am considering one of those fires that looks just liike a
woodburner, sits on a plinth out from the wall and runs on mains gas.

Can anyone tell me anything about them please?

Am I likely to need the chimney lined or however it functioned with
the living flame be sufficient?
