Logburner and money saving

We've just had our first gas bill since having the logburner fitted. And we have saved £60! So chuffed with that, we will have paid for a year's supply of wood in under two months. And for some reason, the children play so nicely in the lounge when it is lit, they want to be in the lounge rather than anywhere else. The only trouble I am having is getting motivated to use my sewing machine in the cooler kitchen!
