The Fairbanks North Star Borough Air Quality has a graph from their website analyzing the comparative fuels in Fairbanks. It is similar to the analysis I completed earlier this week, yet it adds one more component- figuring the combustion appliance efficiency. Fuel is one thing when figuring how much heat you will get, but the potential of the appliance will be a constraint.
Cold Climate Housing Research Center has a nifty guide about the entire systems that may be used in residential buildings:
Alaska Housing Finance Corporation was a partner in this also. Take a look at the type of system you have, the fuels it requires, their prices, and consider what will get you through at a relatively low effort and cost for the next seven years. Check out the Anchorage Home Show September 19-20 for ideas on whole systems that may help your heating bill.
