Ecosmart tankless water heaters are produced by who?

Eemax technically produces Ecosmart tankless water heaters. American corporation Eemax has very clear industrial objectives. The firm claims that the tankless and small-tank electric water heaters they manufacture are designed to fulfil these requirements in residential, commercial, industrial, and safety applications.

  • Safety
  • Code Compliance
  • Sustainability
  • Innovation

Their overarching goal is to create items that supply unlimited hot water while shortening the time to temperature.

A Synopsis of Ecosmart Tankless Water Heaters’ History

Since it was founded in 1988, Eemax has advanced significantly. With its first tankless water heater for commercial use, it got things going quickly. These early water heaters could produce only 0.5 to 1.5 gallons per minute. But by the 1990s, they had updated to Series TwoTM and Series ThreeTM water heaters with up to 5 GPM capacities.

They began making water heaters for residential residences in 2000. By introducing the Series SixTM and Series TwelveTM series of high-capacity water heaters in 2003, they maintained their leadership in the tankless water heater market. These heaters could produce up to 25 GPM and had an industrial capacity.

Riverside, a private equity company, bought Eemax in 2008. This action promoted the water heater brand’s growth domestically and internationally. To broaden its product offering, Eemax acquired Ecosmart in 2013 under Riverside.

Eemax introduced HomeAdvantage IITM in 2014 to enhance its selection of home water heaters. This invention only uses electricity when you need hot water, increasing energy efficiency. It saved money on electricity, was better for the environment, and used less water.

With the introduction of the ProSeries XTPTM as recently as 2019, Eemax continued to develop into a market leader. These electric tankless water heaters need to work at a higher thermal rate.

Ecosmart Tankless Water Heaters: How Reliable Are They?

Because of the dependability of its goods, Ecosmart has expanded. When installing an Ecosmart tankless water heater, there are certain things you should look for.

Ecosmart water heaters excel in a few of these categories.

Electric and Gas Capability

Although electric heaters comprise most of the Ecosmart product range, there is also a series of gas water heaters that either propane or natural gas may power. The nicest thing about being able to use both propane and natural gas is that just one gas valve would need to be changed. Due to the fuel type, you are spared the bother and expense of purchasing another heater.

Condensing and non-condensing gas variants are both available. You gain from their above-average EF score even while they are running low on petrol. The non-condensing units may achieve EF scores as low as 0.82, while the condensing units display EF values as high as 0.95.

The selection of electric water heaters is greater than that of gas-powered ones. Only roughly 36Kw of electricity is used by the ones with high GPM flow rates.

Different Use

Wintertime usually results in less hot water from water heaters. You see, during the colder seasons, groundwater is cooler. As a result, getting hot water takes longer. The more compact Ecosmart electric heaters can serve as tank-type heaters’ backup units. You will always have adequate hot running water even when it is chilly because of the improved capacity.

Additionally, hydronic floor systems allow the use of electric warmers like space heaters.

Use of Low Flow

Water flow is restricted in certain locations by regulations or water infrastructure. A heater that can deliver hot water in a low-flow region is required. Point-Of-utilize (POU) water heaters from Ecosmart utilize 3.5 kw of power. Instead of using Flow Sensor Technology, these heaters use an ON-OFF mechanism.

These little gadgets are tiny enough to fit in little locations. They can be placed adjacent to the laundry area, beneath the kitchen sink, or in the bathroom.

Whole-House ECO Models’ Temperature Control

The ECO versions from Ecosmart are meant for whole-house use. To heat the water as it enters, they consume up to 36Kw of power. Such a device would typically increase your annual utility expenditures.

However, the ECO series has temperature regulation, which lowers your costs. Temperatures between 80 and 140 degrees Fahrenheit are controlled using temperature modulation.

It alters the temperature by 1F increments both up and down. On the monitoring screen of the ECO models, you may keep track of temperature variations.


You spend money on household conveniences like water heaters so they will last a long time. Because of this, Ecosmart tankless water heaters contain corrosion-resistant copper and stainless steel components. Due to the accumulation of corrosive minerals inside the water heater, it degrades quickly. Copper and stainless steel make important parts, such as the heat exchanger, more durable and energy-efficient.

EcoSmart ECO 11 Electric Tankless Water Heater. The EcoSmart is a powerful tankless heater for kitchens or bathrooms and features 13KW at 240 Volts with Self Modulating Technology.

What country manufactures Ecosmart tankless water heaters?

The Ecosmart range of tankless water heaters is produced in China, even though Eemax maintains its headquarters and production facility in Waterbury, Connecticut. However, that doesn’t imply that the final result is low quality. The company ensures that all the heaters meet high standards as required.

Atlanta is the home of the parent firm, Rheem. Rheem has boosted the Eemax brand by adding distribution channels in 30 more nations to its worldwide presence in 14 countries.

Eemax invested in a 7,000-square-foot Innovation Learning Center in the United States to keep up with the demand for improved goods. This site gives engineers, corporate representatives, vendors, and plumbers the knowledge and skills they need to remain on top of any issues relating to water heating.

What is the lifespan of Ecosmart tankless water heaters?

The longevity of a water heater depends on the quality of the water entering it and how carefully you treat it. Tank replicas can last up to 12 years. After then, industry experts will tell you to think about a replacement.

Tankless water heaters from Ecosmart have a 20-year lifespan. Considering the original investment is impressive. Even glancing at what’s inside, Ecosmart tankless water heaters are made to survive that long. A water heater can endure up to 20 years since it is less susceptible to sulfur damage, tank leaks, corrosion, and these other problems.

Ecosmart devices also come with various warranties. While electric water heaters have lifetime guarantees, Ecosmart gas tankless water heaters offer 12-year warranties. When you combine the contracts with routine maintenance, your heater will serve you well for a long time.

How long is the warranty on tankless water heaters from Ecosmart?

Limited warranties are offered on the installation of the heater, heater parts, and gas and electric tankless systems. Ecosmart provides a 12-year guarantee on condensing and non-condensing tankless gas water heater models. Only the heating exchanger is covered by the 12-year contract. The ECO gas tankless water heaters have a 5-year components guarantee and a 1-year labour warranty.

There are several warranties for electric vehicles. A lifetime guarantee covers the heating elements of electric Eco-series tankless water heaters. The POU water heaters, the smallest units, have a one-year warranty.

The guarantee is null and void if you decide to install it yourself rather than having a licensed, experienced professional plumber handle it.

What Issues Do Ecosmart Tankless Water Heaters Typically Have?

You’ll likely experience these issues if you possess an Ecosmart tankless water heater. Most of the time, these issues are simple to fix. An error code is the root of most Ecosmart tankless water heater issues. All you need to do is understand what the error code indicates.

Hard water damages heating elements and scale.

Not all Ecosmart brands use scale. However, one of the major issues with water heaters is hard water, which causes scale.

It takes time for scale damage to cause havoc with your water heater. Due to its gradual accumulation, it may slow down your heating systems and increase your energy expenditures without your notice.

The LED light isn’t working.

This is a typical issue with freshly installed and existing Ecosmart water heaters. Debris accumulation near the flow meter is the most frequent reason for this problem.

However, the Ecosmart troubleshooting manual suggests cleaning the area around the flow meter. If the issue continues, a replacement could be required.

Unit is Activating Despite Not Producing Enough Heat

Insufficient heat suggests that the heating components are malfunctioning. These issues are brought on by air pockets, silt accumulation, or freezing damage. If the readings are lower than five or greater than ten, the heating element must be replaced.

You may perform routine maintenance yourself or hire a qualified professional plumber. Conversely, clean-up will spare you most of the problems with these heaters, provided you have some experience maintaining heating systems. For certain heaters, you may also consult the Ecosmart interactive troubleshooting guide.

An in-depth analysis of Ecosmart tankless water heater trouble codes has been collected.

Ecosmart Tankless Water Heaters Have Known Recalls

Users have been protected from the inconvenience of subpar heaters because of Ecosmart’s dedication to producing high-quality water heaters. There have yet to be any product recalls for their offerings. Their customer care team, troubleshooting manual, and qualified plumbers guarantee that customers’ issues are resolved quickly.

How Do Similar Brands Compare To Ecosmart?

Ecosmart water heaters are on par with other premium heaters like RinnaiNavienTakagi, Titan, and Noritz in terms of quality. Ecosmart tankless water heaters distinguish themselves from other products thanks to two features.

First, unlike Rinnai, Noritz, and Navien tankless water heaters, it does not offer WI-Fi. However, the parent company of Ecosmart, Rheem, sells water heaters with WiFi capabilities.

The POU range from Ecosmart is also noteworthy. With a point-of-use tankless water heater, you can avoid consuming excessive energy for routine, menial chores like handwashing. These products are exclusive to Ecosmart.

Ecosmart stands out from other companies thanks to its high EF score, another amazing quality. Ecosmart employs EF rather than the more recent UEF standard. The highest of all other brands with UEF ratings of about 0.92 to 0.95, Ecosmart tankless water heaters claim EF values as high as 99.8%.

However, like other models, Ecosmart tankless water heaters have certain common characteristics. They are notable for having high energy efficiency ratings, temperature control, and indoor and outdoor use.

What Negatives Can a Tankless Water Heater Have?

The upfront expense of a tankless water heater is one of its main drawbacks. Tankless water heaters are about three times as expensive as tank-type water heaters, although they may offer certain advantages. For a gas-powered model, an Ecosmart tankless water heater can cost $1600. Electric units cost less than $1000, making them more accessible.

Solar-powered tankless water heaters are the priciest models, with unit costs as high as $4000. For solar-powered systems, installation costs range from $2,000 to $6,000.

Water may flow indefinitely from tankless water heaters.

If there are several open outlets at a time, they might be able to produce unending hot water streams. If you have an Ecosmart heater, you may increase the water flow capacity or add a POU water heater.

The unit pricing and installation fees for additional components like vents and gas lines are higher. A qualified plumber will also be required to install them for you to retain the warranty’s validity.

Does a Tankless Water Heater Increase the Time to Get Hot Water?

A tankless water heater takes longer than a tank-style water heater to heat the water. A tankless water heater heats cold water from the input before being sent to the faucet. However, the water loses heat between the intake and the output tap. Additionally, the pace at which you obtain hot water is limited by low-flow faucets.

Solutions from Ecosmart include POU systems and SmartBoosters. SmartBoost is placed on the tankless water system outlet line to maximise hot water output and conserve energy. With POU systems, you get more hot water faster since there is less space between the heater and the outlet.


It would be best to rely on businesses pushing green energy as tankless water system efficiency and technology advance to reduce utility bills. Ecosmart tankless systems may meet residential and commercial buildings’ whole-house water demands.

For installing an Ecosmart tankless system in your house, be sure the plumber is certified.
