Description
Highlights of the EcoSmart ECO 18 Electric Tankless Water Heater
The EcoSmart ECO 18 Electric Tankless Water Heater is built on a reputation for energy efficiency and compact design. One standout feature is its patented self-modulating technology, which adjusts the power usage depending on the water demand. This means it doesn’t draw full power when less hot water is called for, which is where the energy saving comes from. The digital temperature control is simple to use, setting the water temperature in precise 1-degree increments so shower temperature can be dialled in exactly. The compact size of 17 x 14 x 3.5 inches makes it easy to install in tight spaces, and the LED display provides clear feedback on the current settings.
- Self-modulating technology for efficient power use
- Precise digital temperature control in 1-degree increments
- Compact design fits easily into small spaces
Drawbacks of the Tankless Water Heater
Despite the many positive aspects, a few issues in the specification are worth flagging. One limitation is the maximum flow rate of just 3.51 gallons per minute, which means it can barely handle one full shower and one sink at the same time in cooler climates with incoming water around 62°F. In warmer locations where the incoming water temperature is higher, the effective output rises, but in colder regions it will struggle to meet the needs of multiple users simultaneously. Additionally, the unit requires a 240-volt electrical supply, which may not be compatible with all home electrical systems without an upgrade. Installation can be tricky without electrical experience, and professional help might be necessary. The warranty is generous with lifetime coverage on electronics and the heat exchanger, but it only covers the cost of the unit and not labor or incidental damages, which could add to potential repair costs.
- Limited flow rate for simultaneous multi-point use in colder regions
- Requires 240V electrical setup, possibly needing professional installation
- Warranty does not cover labor or incidental damages
Performance and Water Heating Capacity
The real question is whether this electric tankless water heater can replace a traditional tank system. The figures are strong: an 18 kW heating output and a rated efficiency of 99.8%, which means very little energy is lost during operation. This makes it a solid option for those wanting to reduce their energy bills. Because heating begins on flow rather than from a stored reserve, there is no reheat cycle to wait through the way a tank heater requires. The unit is rated to raise water from 62°F at its stated flow, delivering a steady supply for a single shower and light sink use. However, running two showers simultaneously when inlet water temperature is on the colder side takes it past its rated capacity and temperature drops. That makes it best suited for smaller households or locations with warmer incoming water.
Installation Requirements and Day to Day Use
Installation takes some planning. The unit is lightweight at just 14 pounds, which makes handling it a lot easier than bulky traditional heaters. The sleek white finish fits nicely without being an eyesore in utility rooms. The LED display makes adjusting settings straightforward, and temperature changes register quickly. Plumbers who install these note that while the work is doable for someone with electrical skills, the requirement for a dedicated 240V circuit is the common stumbling block. Once running, the payoff is consistent hot water at a set temperature, which matters most in households where shower temperature is a recurring argument. This model’s digital controls hold the setpoint, avoiding the sudden cold bursts common with older heaters.
Product Competitors and How This Model Stacks Up
Comparing this tankless heater to other popular models like the Stiebel Eltron Tempra or the Rheem RTEX series reveals some interesting contrasts. The EcoSmart’s self-modulating technology gives it an edge in energy savings over many competitors that operate at fixed power levels. On the downside, its flow rate is lower than some rivals that offer higher gallons per minute, making those better choices for larger households. For example, the Stiebel Eltron Tempra 24 offers a higher flow rate but comes at a higher price point. The Rheem RTEX 13 is more affordable but lacks the advanced modulation feature and precise temperature increments. If energy efficiency and compactness are your priorities, this EcoSmart unit stands out. However, if you need to serve multiple fixtures simultaneously in a colder climate, some competitors might be better suited for your needs.
Value for Money: Is It Worth the Investment?
Considering the features packed into this compact unit, the price performance is reasonable. The lifetime warranty on electronics and heat exchanger adds value, and the energy savings from the self-modulating tech could help offset the initial cost over time. Since it eliminates standby heat loss common in tank heaters, it’s a smart choice for those who want to reduce their utility bills. However, if your household demands high simultaneous water flow or you live in a region with very cold incoming water, more powerful and often pricier alternatives are the safer sizing. The installation cost might also factor into your budget, especially if an electrician is needed to set up the 240-volt circuit. That said, for small to medium households in moderate climates, this unit offers a solid balance of efficiency, convenience, and reliability.
Upsides to the EcoSmart Tankless Water Heater
- Highly efficient 99.8% energy conversion reduces electricity waste
- Compact and lightweight design fits tight spaces easily
- Digital temperature control allows precise hot water settings
- Self-modulating technology adapts power usage to demand, saving energy
- Lifetime warranty on critical components gives peace of mind
Shortcomings to Keep in Mind
- Maximum flow rate limits simultaneous use in colder climates
- Requires 240V power supply, potentially increasing installation complexity
- Warranty excludes labor and incidental damages, affecting overall cost
- Performance may dip when heating very cold incoming water
Read against its specification, this unit shows how electric tankless water heaters can cut down on energy use and improve convenience, but it’s clear that sizing and electrical setup are the two factors that decide whether it works in a given home.
