Save over 10,000 gallons a year (the manufacturer claims up to 17,000) by installing a hot water Recirculation Pump. This pump makes hot water more quickly available everywhere in the home, thereby reducing the wait for hot water (and thus the savings by not letting all that cold and warm water go down the drain). As an added benefit, not only is the hot water there quicker, it is hotter as well! This is because the pipes will have been pre-heated by recirculated hot water.
I'm installing this one under a bathroom sink, at the point farthest from the water heater. This is the best location. Depending on the actual plumbing configuration at your installation site (i.e., the distance from the other fixtures from the main water line) , there may be a small delay for hot water delivery, while the water between the main hot water line and the fixture is used. However, it will still be quicker delivery and initially hotter water at all fixtures than without the pump installed.
