An electric heater becomes an energy saver because it usually supplies electricity only on demand instead of constantly providing heat. Likewise, a tankless heater is smaller and more efficient. Instead of a tank holding large quantities of water, a tankless heater is much smaller and can be wall-mounted. This also allows its owners to save on interior storage space as well as cutting down on utility costs.
For some, there is the concern whether a small and more efficient on-demand heater can actually produce enough to regularly heat up water within an entire large residence. However, technological advances have moved forward to the point where those issues are no longer anything to be concerned about.
Instead, many electric tankless water heaters provide more than enough water flow to effectively service multiple showers and bathrooms at the same time within a large household. So, an electric tankless water heater provides a number of advantages to its owners in that it is a space saver, an energy saver, cleaner than a tank version, more reliable, and environmentally-friendly.
The following is a list and reviews of five highly regarded electric tankless water heaters that can be found on the open market at the moment.

Best Whole House Electric Tankless Water Heater
The Rheem brand is generally a good one, so their electric tankless heater should make the list. This particular one – Rheem RTE 13 Electric Tankless Water Heater is consistent and durable and can provide energy savings all in one.
Part of its durability is due to a brass copper heat exchanger and overall steel build. While it only provides four gallons of hot water per minute, that is still enough for multiple uses within a household. Because it is electric, it only draws power when water is needed on demand. Add in the tankless-driven space opener and there are a lot of positives to take from using it in your household.
Those who use low-flow shower heads in bathrooms can maximize its somewhat limited water flow because everything else about it works well. When paired with such shower heads, even three and four-bedroom residences can work with its water flow rate.
When it comes time to install a new water heater, a tankless system is a good alternative to traditional tanks as it can save you money in the long run. You need to understand your hot water needs when choosing the right tankless hot water tank for you.
