We burn turf in our kitchen range, in the open fireplace, and in a solid-fuel stove, along with coal and wood (fortunately we've got a lot of ash trees in our field, so we always have branches & off-cuts), though you don't have to mix them. Peter Laban has already said pretty much what I would have written had I come into this thread earlier.

We buy the little Bord na Móna blocks in our village shop-cum-postoffice; and whenever we go up to Donegal to visit Packie we always come home with a bag or two of natural "rough" turf, which is just the unprocessed cuttings, not the symmetrical machine-made briquettes. It has the most unbelievably beautiful (to my nose) smell. Even when walking around the city (Cork) you can sometimes catch a whiff of it.

Packie used to have a huge stack of cut turf leaning against the wall outside his cottage, and he was a wizard at getting the stuff to burn, under almost any conditions (there's something of a knack to it). Then he went and converted to oil central heating, the wuss!! Well, he is 93 soon...
