Ecosmart ECO 36
Ecosmart can easily be considered as one of the best brands that manufacture electric tankless water heaters. They are well-known for offering top of the line eco-friendly products. Although having a wide range of services in different industries, Ecosmart specializes mainly on water heating products such as pool heaters, spa heaters, radiant heating systems, and of course, tankless water heaters. Approximately 25 percent of the average American household’s yearly energy bills come from heating water. Ecomsmart’s goal is to design and distribute high-end green energy water heaters that minimizes energy consumption, thus preserving the environment.
Ecosmart ECO 36 is arguably one of the best tankless water heaters in Ecosmart’s product line. We’ve encountered a lot of positive feedback from consumers who swear by this water heater. If you’re living in a flat or a medium sized home, this water heater is perfect for you.
Few water heaters can hold up to very cold climate areas. However, in areas where temperature can drop to as low as 37ᵒF, the Ecosmart ECO 36 effectively delivers up to 3.5 GPM. This means that it can provide two showers with hot water simultaneously. In hotter areas, the Ecosmart ECO 36 can pump up to 6.5 GPM.
One thing to take note though is that the Ecosmart ECO 36 requires a flow rate greater than 0.25 GPM before it will turn on and begin heating water. Keep in mind that that’s the water flow requirement on the hot water line – not the total water flow.
Stiebel Eltron Tempra 29 Plus
Stiebel Eltron is also among the brands that manufactures one of the best electric tankless water heaters. You can include the Tempra 29 Plus in the top list. Stiebel Eltron has been in the industry for quite a long time. In 1926, Dr. Theodor Stiebel founded the company and became one of the pioneers of modern water heating systems with approximately 160 national and international patents. Stiebel Eltron is one of the leading brands not only in the field of water heating but also in renewable energy and space heating.
The Tempra 29 Plus is one of the most powerful electric tankless water heater in production. Its top quality engineering and design make it a great investment for anyone who’s looking for an electric tankless water heater that will last.
The Tempra 29 Plus can effectively handle being in both cold and warm climate areas. Keep in mind that the lower the temperature of the incoming water, the flow rate also reduces. For instance, at 40ᵒF, the water heater can only provide 3.0 GPM, but at 75ᵒ, it can pump up to 6.5 GPM.
The Tempra 29 Plus is built with a digital temperature display and a relatively hefty knob which allows you to adjust the desired water temperature between 86ᵒF and 140ᵒF (30ᵒC and 60ᵒC).
In addition, the Tempra Plus Series are built with an advanced flow control and true thermostatic temperature control technology that constantly monitors the water flow and temperature. This system adjusts the water flow when it senses that the water coming in is exceeding its capacity. The Tempra 29 Plus’ technology automatically adjusts the power required to heat the water to the predetermined temperature settings and maintains it all throughout.
Ecosmart ECO 27
The Ecosmart ECO 27 is fundamentally a slightly less sophisticate and less expensive version of the ECO 36. You can rest assured that both come with a lifetime warranty when professionally installed. In terms of size and technology, both the ECO 27 and ECO 36 are virtually identical.
The main contrast between the two versions is the GPM where the ECO 36 provides more GPM than the ECO 27. This is mainly due to the ECO 36 higher rate at 36 KW at 240 volts. It has four separate 9KW heaters built in instead of three separate 9KW heaters in ECO 27.
All things considered, if you are living in a small size space and looking for a budget-friendly electric tankless water heater, then the Ecosmart ECO 27 is perfect for you.
Rheem RTE 13
Though the Rheem RTE 13 is seemingly not as sophisticated and stylish as the previously mentioned brands, the best thing going on for this unit is its price point. With other brands of electric tankless water heaters averaging above $500, the Rheem RTE 13 answers your water heating needs for a significantly lower price. It is probably one of the best entry level electric tankless water heater in the market today.
Due to its ultra-compact size (9 x 10 x 5 inches), the Reem RTE 13 is very easy to install. It is ideal for households where taking showers, washing clothes, and doing dishes are not done at the same time. It can also be installed as a backup water heater.
Bosch WH27 Tronic

The Bosch WH27 is a powerful and compact electric tankless water heater that can easily be installed practically anywhere. Its design is ideal for both commercial and residential use. It can handle two applications simultaneously without running out of water.
In addition, it is internally built with an electric flow sensor and modulating control unit that completely eliminates annoying temperature fluctuation.
