"Officially" you should have a DEFFRA compliant stove IF you want to burn wood. Smokeless coal and other smokeless products are fine on an open fire - but not so efficient.( see clean air act 1971) The wood burning stove radiates more heat into the room, hence it's more efficient to run. Though it's not a cheap option, you can take the stove out and take it with you when you leave. Design wise, there's a dearth of naff/cutesy Mrs Hedgehog style logburners to wade through, but with a little patience you'll find a neat modern one to suit your look. Make sure you opt for the multi fuel model, it's more flexible fuel wise. Wood combined with a little smokeless coal is optimum. I'm fond of the Danish made Westfire. It's got a nice deep firebox, performs very well and looks good, with a neat flat top plate that you can put a pan on to slow cook with. Lastly, its cleaner & very enjoyable. We've enjoyed many a good "hot-yoga" session in front of one.
