Cords for small power tools like sanders and drills can get in the way when you work on a bench. One trick to keep them from interfering is to make up a chain of heavy rubber binders. Loop one end of the chain onto the cord about a foot behind the tool. Loop the other end over a cup hook screwed into the ceiling of your shop. When done, unhook from the cup hook and put the tool in storage.
Look for the EnergyGuide label that tells how much energy the water heater uses in one year. Also, look for the FHR (First Hour Rating) of the water heater, which measures the maximum hot water the heater will deliver in the first hour of use. If you typically need a lot of hot water at once, the FHR will be important to you.
