Unless you are building a new home or are trying to make your current home more energy-efficient, you probably don't think much about how your water gets hot. In fact, chances are good that if you are buying a new water heater, your old one is on its last legs or no longer works at all.
Consumers now have more choices when it comes to water heaters than in the past. These days, the standard tank water heater has some eco-friendly tankless competition, but even tank heaters are available in high-efficiency models. It is estimated that we spend up to 30 percent of our home's energy budget on heating water, so making a good choice can pay off for years to come.
