Tired of fighting a shortage of hot water and battling skyrocketing energy costs? Defeat an energy cheater with a high-tech tankless water heater. Two of every three remodeling jobs involve kitchens and baths, and hot water is a key element. Today's products such as multi-head showers and bigger tubs use a lot of hot water. Only a "tankless" water heater with a never- ending supply line can keep up with the need. It's 70 percent more energy efficient, too. And, you heat water only when you need it.
