Tankless electric water heaters only heat water when it is needed. About 8% up to 30% of the energy consumed by a standard water heater goes to keep the water hot while it’s not being used.

Before making a purchase, what important things do I need to consider?

1. If I want to install an electric tankless water heater – what information do I need? Well – you should check out what amount of amps and volts that the electric tankless water heater uses – and again – the best idea it to check out the tech and specs of the water heater you are interested in or download a install manual above for all the information you can get. And also each gas tankless water heater has special needs – so the best idea it to check out the tech and specs of the water heater you are interested in or download an install manual above for all the information you can get.

What are the advantages of a tankless electric water heater system?

About last for about 20 years and are smaller than hot water tanks, tankless electric water heaters are designed. A tankless electric water heater also known as a point of use water heater or on demand water heater turns on when you open a hot water faucet and turns off when you close the faucet, so the energy that is consumed is only for the hot water that is being used. Since there is no storage of hot water and thus no constant heating and re-heating of stored hot water, you’re not wasting energy heating water when you do not need it, such as when you’re sleeping or not at home. This energy savings translates to dollar savings for you and reduced impact on our environment. Therefore, since a tankless electric water heater heats the water as you use it, you can have an endless supply of hot water, provided you size the unit appropriately.

How do tankless electric water heaters work?

When we give a hot water by open a hot water tap, the cold water enters the heater and triggers is heating elements or burners to turn on. Your hot water tap acts as an ignition key for the energy used to heat the hot water you need. The water is then heated as it flows through the heating elements or heat exchanger. As you change the water flow, a water valve or thermostat controls the heating elements or burner flame to maintain a constant temperature. The amount of energy used is always proportional to the volume of hot water being used. When the hot water tap is turned off, the system shuts down. That is all the principal working of tankless electric water heaters, and it so very simple.
