EcoSmart tankless water heaters: Models and features

EcoSmart tankless water heaters, available on Amazon, come in several sizes to fit various needs. The smallest model is the 3.5 kW POU, recommended for point-of-use service where low water flow is required. The ECO models, on the other hand, have up to 36 kW of power and are designed for whole-house applications for demanding households.

One of the main differences between the two types, aside from capacity, power, and electronics, is that the point-of-use (POU) models do not utilize Flow Sensor Technology like the whole-house units. This makes them simple to use with only an ON/OFF option.

EcoSmart electric units are also designed as water heating boosters to increase the capacity of tank-type units and as solar backups to provide continuous comfort during colder days when solar panels are not operating efficiently. They can also be used for space heating in hydronic floor systems.

Thanks to its tankless design, EcoSmart ECO water heaters are small, compact, and lightweight, requiring minimal space for installation. These features make them easy to handle and install almost anywhere, including under the sink, above the sink, on the wall, in the kitchen, bathroom, office, garage, basement, RV, or small business.

For point-of-use applications, there are two models available - POU 3.5 and POU 6. Both models have an attractive design and small size, measuring only 6" x 11" x 3". They are mainly used for one to two bathrooms or kitchen sinks. The power button allows users to turn the unit ON or OFF and adjust the water flow to increase or decrease the temperature of the outgoing water.

Larger models, such as ECO 18, ECO 24, ECO 27, and ECO 36, are whole-house water heaters that provide much more hot water than the previous models. They can supply enough hot water for a comfortable shower, even in colder regions where the incoming water has lower temperatures. Unlike POU models, ECO models use modulation and electronic control to regulate the temperature, and both types have a screen to display the temperature.

With dimensions of 17" x 21" x 3.6", the ECO 36 is the largest unit and the most powerful water heater from EcoSmart, with four 9 kW heating elements and a total power of 36 kW. It can produce up to 4 GPM (45 F temp. rise), providing plenty of hot water to multiple fixtures.

Self-modulation

EcoSmart tankless water heaters are designed for whole-house potable water heating and provide hot water on demand. They require a minimum water flow for activation and use a flow sensor to modulate power consumption based on the water flow rate.

This ensures efficient energy usage, reduced fluctuations, and greater comfort and savings. With a low minimum water flow rate of 0.25 GPM, there are no issues with hot water delivery, even with low water pressure or when mixing hot and cold water.

Easy temperature control

The outgoing hot water temperature can be easily adjusted between 80 and 140°F in 1°F increments using the temperature controller, while the digital display provides convenient monitoring and status checking. It's worth noting that this feature is exclusive to EcoSmart ECO whole-house and tankless water heaters.

Enough power

The ECO series water heaters from EcoSmart provide just the right amount of heat for a comfortable shower or washing dishes, with the power output varying depending on the received voltage. The heating elements are standard-type and screwed into the heat exchanger, ensuring a straightforward installation process and quick, easy replacement when required.

One of the key benefits of these heaters is their durable copper construction, which helps to prevent corrosion and extend the product's lifespan. Additionally, as these water heaters are tankless, they can instantly and efficiently heat water on-demand, greatly reducing energy and water consumption. This eliminates standby heat loss and ensures that there is always fresh, hot water available.

Safe and reliable

EcoSmart tankless water heaters are an eco-friendly option that can significantly reduce energy consumption and carbon footprint as they don't produce any combustion by-products like gas models do. They are also smaller than tank-type heaters, resulting in less waste going into landfills in case of a breakdown. Additionally, most of the components of these heaters are replaceable, further reducing waste.

Compared to tank-type heaters, tankless models have a longer lifespan of over 20 years, and come with a limited lifetime warranty. They don't suffer from problems like corrosion, tank leakage, anode rod issues, or rotten egg smells, making them a reliable and durable choice.

Feature highlights

The EcoSmart tankless water heaters offer several benefits over traditional tank-type heaters.

• The tankless design provides on-demand heating and endless supply.
• Small and compact size.
• Digital temperature control.
• Copper and stainless steel components.
