Today they are set up in most zero energy homes. Also today, most custom homes are being designed with a whirlpool system, high output showers, showers or tubs in other rooms, large capacity washers and dishwashers. All of these put a huge strain on a conventional water heater. Then there is a recovery period when even the biggest units run out of hot water.
A tankless water heater is fairly easy concept. Instead of a constant draw on resources to heat, maintain and reheat water in a large tank. The tankless water heater will flash-heat the water as it is needed by running thru a heat exchange. When hot water is needed sensors will signal the burners to light and then heat the water. When the hot water is no longer required the entire system just shuts down and there is no pilot light. This and the fact that there is no recovery period you can save 40 to 60 percent on your utilities costs.

While there are several good advantages to the tankless water heater, there are some drawbacks also.
The flow rate or capacity that a tankless water heater can supply is dependant on the heating element. The bigger the heating element is. The larger the capacity or flow rate will be. It is also affected by the difference between the water temperature and the temperature it requires to get heated. This is also known as rise.
If a tankless water heater needs to heat water from extremely hot, such as the case in the colder regions. It will have a lower flow rate. A typical shower temperature is 105 degrees. If the water needs to be heated from 65 degrees (which is common) to 105 it will do so a lot more efficient and with a greater flow then heating the water from 35 to 105 degrees.
