January 6, 2017 | Author: | Posted in Water Softener Reviews

A water heater which is powered by electricity and heats water eliminating the need of a tank reservoir is known as an electric tank reservoir. Basically, it heats fresh water while it passes through, without the water getting stored. Due to this feature, it is often called as on-demand water heater. 
Depending upon its usage, electric tankless water heaters are differentiated as below: 
•  Electric heaters that are used as point of service which are located near the source where a person may require water. 
•  Those which service an entire house. 
•  Those which are used for commercial aspects like industries. 
There are some heaters which heat the tank even when there is no requirement of it. This paves way for electric tankless water heaters. 
As there are many manufacturers, many different models in a variety of shapes, sizes and capacity are available. Some variations utilize propane or other types of gases for heating as well. Such types are more efficient if they are installed for an entire house. Depending on the temperature of water which needs to be heated, the power requirement also varies. 
If you want to heat water which is already very cold, a significant amount of electricity or power is utilized. Hence, it is very important to choose an electric tankless water heater depending upon the area where you live as this influences the average temperature of water. 
Even if all these factors are taken into consideration, tankless electric water heaters are more efficient that other electric heaters used for heating water. For normal tank aided water heaters, once the tank is emptied, new water takes its place and this would require heating again (chances of loss of electricity or power), but these heaters also have their valid advantages as well. 
On a lighter note, electric tankless water heaters provide unlimited supply of hot water which may lead a person to take shower for a long time. One disadvantage of this heater is that it takes sometime before the water is heated, but this time is not very long, often only some seconds before the desired effect starts. 
All in all, usage of electric tankless water heaters is on the rise because it saves a lot of money on costs related to standby losses.
