As a PP said, it's not necessarily the most cost effective way of heating a home if you aren't able to get your hands on free or unseasoned, cheap hardwood.
Iirc you can season wood yourself and it has to sit to dry for a couple of years before you can use it. That stuff's cheaper. You don't want to risk using it before: the sap will stick to the inside of the chimney and set it on fire (it happened to my parents when they were renting a barn whilst building a house).
The seasoned, ready to use wood, which we got delivered from our local farm shop. Well, that went up from £80 to £110 a builders' sack (1m x 1 m x 1m, approx 750kg) over the 3 winters we had to use one (22-beginning 25), and they ran out early Spring each year too.
You can buy softwood for a lot cheaper, but that does what you'd expect: you'd burn through it at a rate of knots.
But, it depends on how you use your heating, and what the weather's like where you live, and how 'connected' you are. We were in a small village where nobody would give a rat's arse if our power went out for 48 hours, and we had no gas supply, so the woodburner could have been a useful backup.
As it turned out, the underfloor heating was so poxy (installed incorrectly) and the wind so very violent on such a regular basis that we basically couldn't control the temperature of our house at all, it was either balls off cold or too hot to walk on. So, we only had the UFH set to come on from 4am til 10am then in the evening, we'd snuggle up and if the cold was unbearable we'd light a fire.
They're actually pretty fast and easy to do once you get the knack (or, the right firelighters/kindling).
So, I certainly wouldn't get rid of a woodburner until I'd had at least one or two winters of seeing how my house behaves during different seasons.
And - if I was in a built up area - I just wouldn't use it. Not fair on people who get no say what's getting in their lungs (we had no neighbours to speak of).
