started out good this year.. mild winter... way ahead of the 4 tons per winter normal usage.. 24/7 burners. somehow ended up doing 4 tons again....the chilly nights wouldn't stop for weeks and guess took me into the stash that i thought was not going to be used.. but, we did bump up the temperature of the stove bit higher this year.. getting older and feeling the cold more I assume so there is that.......... every 1 degree up makes a difference alas....
