Reply #4: Wrap a brick in aluminum foil and put in the tank...saves water...

and you can use the money to take care of other more immediate concerns. You might even need TWO bricks, hard to say. My plumber was the one to recommend the adding of the tin foil..guess it is to keep it cleaner.

Sounds like your home is an older one, as is mine, and the biggest thing that made a difference was adding insulation in the attic. I also had someone go through and make sure I had no air leaks in my ductwork which was in the crawl space. This will help you with your energy bills.
