However, the problem here is that energy is used on a regular basis whether you need hot water or not. In other words, the energy is lost in this process unnecessarily. This is called standby heat loss. And, a tankless water heating system eliminates standby heat loss completely, which makes the water system tankless more efficient and acceptable in preference to conventional tank water heating system.

Water system tankless uses a powerful heat exchanger to optimize its performance. As you may have noticed, heat exchangers are used in air conditioners, refrigerators and car radiators. True to the name, a heat exchanger is a device that transfers heat from one source to another.
In a tankless water heating system, its heat exchanger transfers heat generated by electric coils or a gas-fired burner to the water that comes out of your faucet. In the system, the incoming flow of water activates the heat exchanger as you turn on your hot water tap. When the water circulates through the activated exchanger, it heats the cold water to the level you have preset the temperature. Depending on the model of your system, the water becomes hot within seconds, and ready to use. When you close the tap, the process ends and no energy is wasted.

There are different varieties of tankless water heating systems available in the market today. The main types are Point-of- Use Water heaters and Whole house tankless water heater system. The Point-of- Use Water heaters are small and designed to serve one or two outlets. Because of their small size, they can be installed at any place. If you install it closer to the outlet, you can save the time lag significantly.

Whole-house tankless water heating system is meant for the hot water needs of the whole house, as the name suggests. Obviously, the system is larger and suffers from time lag as it cannot be installed anywhere you like.
