Think about the future. All counties in Washington and the state are looking at carbon emission tax for your homes. They are currently creating a database to be able to apply average carbon loads for homes. If you use gas of any sort gas you will pay more tax and you will also pay a tax for chimneys. I believe that studies show that electric baseboard heating is the most efficient form of home heating available because you can set your house up in zones to manage the usage/cost.
