yep, alot easier to clean... takes 5 minutes after my shower, and it looks great most the time I left it a few days, a few days ago, and you wouldnt beleive how messy it all got!
To unblock a chimney, all you have to do is rip out the fireplace, and get it swept. We did ours in our old house, and it was soooooooooo cheap and soooooooooo warm. We didnt need the radiators on as much. Just used newspaper, little blocks of wood, coals then topped with a log... that would last all evening.
