It's a portable unit like
this one
I put the vent hose up a disused chimney and feed it through a sheet of cardboard and polystyrene taped to the fireplace to seal it. Rated 8,000 BTU, that's about 2.5KW
Came from B&Q a good few years ago.
Full tilt the fans and compressor make some noise but it's not too disturbing.
