Tankless water heaters are a great way to save energy. What they do is instead of regular water heaters is they heat water as it flows through it and not heat water that's in it. My family got a tankless water heater and now we are not using as much water for say showers because before we were having to wait till the water got hot. So we were actually wasting a lot of water and gas becasue it took longer to heat the water because there was so much water in the tank. It not also saves energy but regular water heaters would run out of hot water and you had to wait for more water to enter the tank and heat up. But one thing that you have to be careful of is not to over indulge and take 20 minute showers because you're not really saving water if you do that.
