Most of us have either seen or used a water heater or a faucet in the bathroom to provide localized hot water. However, the concept of tankless water heaters is something that is new to many of us. According to the producers of these systems they are more efficient at heating water as and when required saving much electricity and natural gas compared with other heating systems.

However, the United States government disagrees with this and so do its citizens. The basic difference between tankless and conventional heaters is that in a tankless heater, the pipes that supply hot water are always kept hot so that water flowing through it naturally gets heated through convection process. In a tank water heater, the tank is directly heated so that hot water is supplied to the house. Obviously, it takes longer with a conventional heater to heat water as opposed to a tankless heater. A good way to learn more about these systems is to read some tankless water heater reviews which can easily be found online.
