Our Review

Like all of the other models in the Ecosmart line of tankless water heaters, the Eco 36 is easily recognizable for its compact, user-friendly digital interface. This digital display system makes it easy to adjust the system’s output temperature up or down a few degrees (when you aren’t simply relying on this model’s fully capable self-modulating thermostat).

Throughout this model, you’ll find that Ecosmart has spared no cost in making it durable and long-lasting. Most joints and water-contacting components are built from dense copper, as well as other stainless metals that should ideally resist corrosion. If well cared for, this model can be expected to last a decade or longer.

When running at its 6 GPM maximum, the Ecosmart Eco 36 is capable of providing four showers and a sink with a steady stream of hot water simultaneously. You could even use this unit to fill and maintain a jacuzzi located on your property away from your home’s primary hot water delivery system.

Why Might I Want this Specific Tankless Water Heater?

Like most tankless water heaters, the Ecosmart Eco 36 is capable of providing instantaneous hot water to can connected outlet. However, the Ecosmart Eco 36 is unique for its ability to self-modulate to accommodate differing input water temperatures. This ensures that all hot water coming out of this unit is always safe and comfortable for contact with human skin.

Also, you may consider picking up the Ecosmart Eco 36 specifically because of its price. At just over $500, this model is an exceptional bargain among other 6 GPM units. This model’s inclusion of a lifetime warranty solidifies its modest price tag as a worthwhile investment in the future efficiency of your home’s decentralized hot water delivery system.

Key Specifications and Features to Look for in a Tankless Water Heater

Dimensions & Capacity

Simply put, if a water heater unit is too bulky, you won’t be able to properly mount it in your desired installation location. The Ecosmart Eco 36 measures up at 17 x 19 x 3.8 inches, which makes it fairly compact compared to competing 36 kw models. Unlike tank water heaters, tankless models like the Ecosmart Eco 36 lack a “capacity” because their instantaneous heating actions negate any need to store water internally.

Fuel Type

Today, tankless water heaters either run on natural gas, propane, or straight electricity. Most shoppers select a model that uses a fuel source for which their home is already equipped to safely deliver. The Ecosmart Eco 36 is electric-powered, making it easy to install in most homes without the need for external venting.

Flow Rate & Water Pressure

A unit’s flow rate describes how much water can be pumped through its system in a minute, often measured in gallons per minute (GPM). This rate, in turn, effects the measured water pressure once the output water reaches an outlet. The Ecosmart Eco 36’s 6 GPM is modest and middle range, indicating that it will be able to serve the needs of most small to medium families in terms of simultaneous hot water demand.

Heating Capacity

A unit’s heating capacity is a range of temperatures into which all output hot water will fall. In other words, a unit’s heating capacity describes how capabile the unit is at completing its primary function. The Ecosmart Eco 36 can heat ground water all the way up to 140 °F, which is plenty hot enough for all types of personal and applicational cleaning.

Energy Efficiency Ratings & Certifications

As its name suggests, an energy efficiency rating describes how much of a unit’s input power is translated into the primary task of heating water. The Ecosmart Eco 36 carries an ultra-high 99.8% efficiency rating, which is a testament to its ability to save users on their future electricity bills. Despite this, the Ecosmart Eco 36 doesn’t carry a certification (such as an EnergyStar rating) to further back up this assertion.

Price and Warranty

Even among high-performing models, most tankless water heaters are fairly affordable (especially compared to the installation and maintenance costs associated with tank units). The Ecosmart Eco 36 fits squarely in this affordable price range at just barely over $500. A lifetime warranty also adds a great deal of value to this model, as well.

Display Type

User-friendliness is important, given how often you’ll likely need to interact with a tankless water heater unit. Some modern models like the Ecosmart Eco 36 make use of a majority-digital interface that is both easy to manipulate and easy to read at a distance. Some lessor competing models still use antiquated analog controls, which are challenging to decipher at times.

Different Uses for a Tankless Water Heater

Decentralized In-Home Water Heating

No other water delivery solution compares to a tankless water heater when it comes to decentralization. Individual units like the Ecosmart Eco 36 can be placed in a kitchen or a bathroom in order to directly supply those locations with a reliably supply of piping hot water. This type of decentralized system is ideal for those who want to adjust their delivery system’s output temperature based upon the season’s expected groundwater temperature.

Cutting Water and Electric Bills

Efficiency and savings is the name of the game when it comes to tankless water heaters. Due to their on-demand operational orientation, tankless units like the Ecosmart Eco 36 are able to cut out almost all of the water and electricity typically wasted in a tank unit. The Ecosmart Eco 36, in particular, carries a 99.8% efficiency rating, which is a positive indicator of how able it is to save user money on their utility bill due to its minuscule volume of waste.
