EcoSmart ECO 11 Electric Tankless Water Heater

Review of EcoSmart ECO 11 Electric Tankless Water Heater

One of the many things we hate around the house is not having hot water when we need it the most. Whether you need it for washing the dishes or for a shower, hot water is essential for feeling comfortable in your home. We can all enjoy the benefits of a cold shower any now and then. However, we shouldn’t have one every single day.

Why should you use tankless water heaters?

It’s going to take a lot more than a couple of words to list all the benefits of tankless water heating systems. Since the name is a tale-teller, it’s evident that the tankless water heating systems have no tank. They give hot water on demand, until the end of times (or at least for a decade). Using energy only when producing hot water, it’s also evident that tankless water heaters are going to reduce your bills.

With water not staying in the system like in traditional water heating systems with tanks, the risk for corrosion is reduced. It’s why the tankless water heaters will last longer than the conventional systems with tanks.

Whether you go with gas or electric, tankless water heaters are the best buy for a home. They’re also good for the environment, with most models being highly energy-efficient and environmental-friendly.

How to describe EcoSmart ECO 11 Electric Tankless Water Heater briefly?

In all fairness, the popularity of EcoSmart ECO 11 Electric Tankless Water Heater speaks volumes, and you should trust us on this one. There are plenty of reasons for its popularity, with reliability and affordable price being the selling points.

The energy efficiency rating of 98% is impressive, and the EcoSmart ECO 11 Electric Tankless Water Heater is durable, despite its size. Just as the majority of tankless water heaters, this one is also compact and saves storage space- another benefit of the tankless heating systems.

Do the technical specs explain its popularity?

The first thing you’re going to notice on the unit is its compact shape and small size, which eliminates the problem of finding the best storage space. The small size also explains the low energy use of the unit. It only needs 11kW of energy while running at 240V. The power consumption impacts the heating power you obtain from the water heater.

The EcoSmart ECO 11 Electric Tankless Water Heater is made with Self Modulating technology, which explains its overall performance.

Thanks its power consumption, the EcoSmart ECO 11 Electric Tankless Water Heater is a valid option for point-of-use water heating applications. If you install it close to a showerhead or a faucet, the unit is going to produce enough hot water for a shower (at 1.5GPM/5.7LPM) and a low-flow faucet simultaneously. The technical specs make the water heater a reliable option for medium-to-warm regions for a studio or small apartment.

Installation should run smoothly, especially if you follow the user-friendly instruction from the manufacturer. The unit allows a straightforward wall mount.

Operating the unit is a breeze thanks to the temperature control. You can easily make the settings you like on the digital temperature display, adjusting the temperature by 1-degree increment.

The lower the groundwater temperature, the lower the flow will be. Installing a carbon filter on the inlet water is going to provide better performance for the unit. Anyway, the water heater needs little to no maintenance.

Should you live in an area with groundwater temperature ranging at 80F degrees, you may use two entire bathrooms simultaneously. However, the unit is reliable only as a single point-of-use option in a cold region. Due to the high energy efficiency (98%), you can install several tankless water heaters in your home and still get a lower electricity bill.
