Ouch! A $326 home heating bill!

[Hudler]

The 1% you save on heating costs is if you keep it 1 degree lower all the time. Say you normally keep your thermostat at 68 degrees,lowering it to 67 will net you that 1%. If your lowering the thermostat to 50 during the day,and it actually drops to that temp,your going to use just as much gas/electric as you would if you kept it at a comfortable temp.The amount of time the furnace runs to get it back to the comfort temp will be vastly longer than just maintaining a set temp.

For Popeye: For a duct system to work properly it will pressurize the main trunk first then the runs to each room,and if done correctly it will heat each room evenly. If you close off too many registers it can negatively impact the whole system. This is more vital during AC season,but during heating it can become a factor if the furnace isn't sized right or if it's an older system that is getting weak.
