Almost two-thirds of homes weatherized receive some sort of improvement to their water heating systems. Most have insulation added to the water tank and pipes, and an even larger number receive low-flow showerheads. Reducing the flow of hot water through these low-flow devices is a very effective way to reduce unneeded consumption, and such devices are now commonplace.
