We live in your typical turn of the century cold drafty two story white frame farmhouse. It has a oil furnace that was converted from coal ( whatever it is it is probably older than me). Each year it has become less and less reliable and more and more expensive to use. Unfortanetly Iowa is not known for mild winters and my familiy is looking for suggesstions on different furnaces, wood burners, fuel types. I hope this doesn't open a big can of worms. Currently I am staying warm with the wolfhound , a cat , and one toddler under grandmas quilt. I also discovered the clothe dryer can throw out a lot of heat in a pinch.
