Think about your hot water requirements carefully prior to making your final selection of an electric tankless water heater. Look at all your different appliances, sinks, and baths that regularly use hot water. Knowing your usage will help you determine the best electric tankless water heaters to put in your home. Hot water which is delivered to your appliances and faucets is measured in GPM (gallons per minute). This is known as the flow rate. 
 
Most regular homes need to have hot water available to more than one place at a time. Events which typically use a lot of hot water include taking a shower and running the washing machine and dishwasher. Most average sized homes will require an electric tankless water heaters flow rate of at least 3 GPM. Homes without many faucets or appliances that use hot water can purchase a tankless water heater with a lower flow rate. 
 
Taking an inventory of the faucets and appliances in your home that deliver hot water can give you a good idea of the type of flow rate you will need. Another thing you will need to think about is the electrical requirements of an electric tankless water heater. To heat water on demand the unit will use a big surge of energy. Most electric tankless water heaters will need a 240 volt electrical outlet. They will also need between one and three 60 amp circuits on your circuit breaker. 
 
Different electrical requirements will come with different models and you need to know the needs of the model you are interested in. You will need to select a system that matches the electrical capacity of your home. The efficiency of an electric tankless water heater will be impacted by how cold the water is to start with. Those who live in colder climates will need a larger capacity tankless water heater to heat the cold water as it comes into the system.
