Buying Guide
Whenever we go to the market to buy the best tankless electric water heater, it is hard to choose one. Purchasing a tankless heater does not only mean just picking one. It comes with a lot of consequences. Before going to the market, it is better to do proper research and evaluate your requirements with the features that simultaneously make the purchase a much easier and more economical task.
The Adequate Size Guide
Electric tankless heaters are available in multiple sizes. Each of them comes with its specific features. The electric heater you should get for your home should be the one which goes with your needs. The electric heaters are available in small, medium, and large sizes.
The first factor you should keep in mind before buying an electric heater is the space you have to install a heater. If you have more space, it is better to go for a large heater, and you can go for a medium or small heater if the space is less. But this factor contradicts the usage. You have to evaluate hot water needs during peak usage hours. See how many taps work simultaneously and how many washrooms there are in your house. If the usage is high, you should go for a large one; if the use is shallow, you can go great with a small one. A mismatch of requirements with the size might result in less hot water.
Another factor you should keep in mind before buying a heater is the area’s temperature. If you live in an area with low temperatures, looking for a tankless water heater that can work with high efficiency to heat the freezing cold water and make it perfect for your usage is mandatory. If you live in an area with high temperatures in winter, you can go for a small heater that would work to heat the water, which will go well for your needs.
What Are You Going To Use The Heater For?
Whenever you buy a tankless heater, it is imperative to see what you will use it for, either for the whole house or a single tap or faucet.

Most tankless heaters require a proper fitting, so moving them from one place to another is sometimes challenging. If you plan to move your water heater from one place to another, it is better to buy a portable electric tankless water heater.

The Flow Rate
The flow rate of a water heater is measured in GPM. The GPM means gallons per minute. It is imperative to see how much water can flow through your heater at once. To find the right GPM value, you have to estimate the amount of GPM used at a time in your house. That includes all your showers and taps. The natural temperature of the water also reduces the GPM value. Choosing the correct GPM value will help you to use all the taps at once in your house. More GPM value allows you to use all the taps simultaneously. A large instant tankless water heater will help you do all the household at a single time.
