I was sitting in the living room last night and I thought I heard thunder. took me awhile but I realized the Mr had turned on the furnace! Never realized how loud that thing is when it kicks on. The furnace the Frigging furnace! our fuel tank is almost empty. What are you doing I ask him. I am cold and its damp in here he says. oh lord. We have had the pellet stove off all week because it warmed up and he didn't want to go to the workshop and bring in a bag of pellets in the rain. I shut the furnace off and turned on the pellet stove.
