We have a gas fireplace embedded in the wall of main house and vacation house, plus a portable stove-fireplace-looking electric one. The electric works, takes about 30-60 minutes to get a room up to temperature. Closed room, 10x10x8 or so. The electric one hums while it's running, but nothing annoying by any means. Black stove body, fake flame picture things. As for the gas fireplaces, they're wonderful. Primary source of heat for the family room of each house, at about 30x15x15 and 30x20x10. Slight pinging sound as they warm up with a very small hiss, once they reach full temperature, the blower kicks in. That's a little loud, but it becomes background noise after the first few runs. Real gas flames, logs look decent too. I might be able to find pictures tomorrow.
