We have had one for many years, cant remember what make tho, all i would say is dont get one thats too powerful/big for your room, they are designed to be opened up sometimes, ours is too big as i was afraid of being too cold! remember you can always make it hotter. We are unable to light ours if we have a house ful or when it is slightly warmer as its unbearably hot in the house. It does also heat the whole house (not small 4 big bedrooms) when it is alight. Brilliant things. BTW ours is a multifuel, not just coal, we burn phurnacite too, and my daughter says it looks like a real electric fire! which we find a good thing about it - when its colder like it has been recently the coal stays in 24/7 unlike wood (unless there is someone at home to make it up throughout the day)
