With a PowerStar tankless hot water heater, water will be heated on demand, saving you a significant amount of energy.

There are two main types of PowerStar water heaters, the whole house water heaters and the point of use.

When choosing the right PowerStar tankless water heater a lot depends on the tempeture of your ground water. A good rule of thumb is that if you live in the upper 2/3 of the United States it is best to stick with the AE125. The main advantages of using the PowerStar AE125 over the AE115 is that it is able to handle a cooler ground temperature.

The most common problem with whole house tankless hot water heaters has to do with sizing. With a traditional system, oversizing your system can often lead to large, uneeded energy consumption because you are forced to constantly heat the entire tank. When oversizing a tankless system, you dont need to worry about keeping a large amount of water heated because the system only runs on demand. Where it might cost you a little bit more for the larger system your energy useage will be relative to your hot water need. When determining the right system you are far better off oversizing a whole house tankless water heater than running the risk of losing hot water.
