I have a gas hot water system which only gets used on extremely cold northeast PA winter days. We've had a wood burner in the basement for almost 30 years. This pretty much heats the entire house. The interior basement walls are brick, with an air space between the cinder crete foundation and the brick. The basement is too small for a layout, and there is no other space at this time in the house for one.
My layout is suspended around a covered patio attached to my workshop. The workshop is heated with a wood burner as well. With the attic door closed, the space is quite comfortable in a tee shirt on normal winter days. When the temperatures get into the single digits, it's not worth feeding the wood burner.
A few years ago, we closed in our 12' X 16' deck and heat it with a gas stove. This room is where the trains are displayed, and serves as the Christmas layout space.
We have a fire place in the front room which is directly above the wood burner, so it is only burned for entertaining, or during cold snaps. Convection is a wonderful thing, so with strategically placed vents and returns, the house is quite cozy, with the exception of the attic which is used as a bedroom. If the door is kept open though, it does get some residual heat. I do have to mention that the house is just under 1000 sq feet, so it's not a large home.
As long as I am able to do the work involved using wood as fuel, we'll continue to use it. It is good exercise too! I get a lot of help from three strapping sons.
