We have just taken ours out. It was in this house when we moved here in 2012. I found it very hard to regulate the heat. It always got too hot in the room and I also found my arthritic knees increasingly made tending to it difficult.
So in the interests of future proofing our home for our older age, we have had a look alike electric stove put in. We can have the flickering flames effect without heat and as our CH is very efficient, this suits us. It may be that we shall use it to warm things up in a cold snap or in spring or summer, when the CH is not on, on cooler evenings.
The pollution aspect also concerned me somewhat, as wood burners are proven to emit particles which are injurious to health. We didn't use ours very often anyway because of the problems mentioned above, but are pleased to be able to claim green credentials from our eco-warrior DGD!
