Heat only rooms you really use. During the Winter, close off rooms that you don't really need to have heated. Remember that every cubic foot of air takes energy to heat, so you should minimize the volume you're heating.

Close off heating ducts for the rooms you're not using. You can buy magnetic covers at hardware stores that provide a better seal than just closing the vent
