A tankless water heater is a great way of reducing your energy cost and helping the environment. Unlike traditional water heaters that keep on heating a lot of water which is stored in a large tank, tankless water heaters simply lets water pass through a heating pipe when a tap is turned on.
Tankless water heaters can be powered by both gas and electricity. In the case of electric tankless heaters, the water is usually heated up be a electric heating element, while a gas heater uses a gas burner to heat up the water.
An important consideration when buying a tankless water heater is the amount of water you will be using at the same time. A typical tankless water heater can produce between 7 and 15 liters of hot water per minute. In large homes however, you might need more than one tankless heater for a proper supply of hot water.
There are many companies that manufacture tankless water heaters. The top brands are Bosch, Noritz, Takagi and Rheem. In Some places the water temperature can be very low, this is where you will need a reliable system that can deliver hot water continuously. In such cases the amount of water they will be used needs to be calculated properly.
Gas heaters can either powered by propane or natural gas. You will also have to examine your current gas line to make sure that it will be able to support your new tankless water heater.
If you choose to buy an electric water heater you need to consider three things, the Voltage, the Amperage and the Circuit Breaker. The voltage of most heaters range between 110V to 277V. You will also need to make sure that your electrical system can support the Amperage demand of your water system. Your circuit breaker might also have to be reviewed; the Electric Tankless Water Heater might also have to be installed on its own circuits.
It might cost some money to install a new tankless water heater, but the energy savings will make up for this cost. Apart from that you can also get a tax credit which always helps.

I’m absolutely agree with that the tankless water heater saving money. I use this type of water heater 1 year for hot water – with a capacity of 2 gallons per minute. Now my bills for hot water have decreased by half.
How Tankless Heaters Work?
1. The hot water tap is turned on.
2. The water enters into the heater.
3. The water flow sensor, detects the water flow.
4. The computer ignites the burner.
5. The water circulates through the heat exchanger.
6. The heat exchanger heats the water to designated temperature.
7. When the tap is turned off the tankless unit shuts down
