Electrical Requirements

Before purchasing an EcoSmart, please make sure that your home has sufficient electrical capacity. Please refer to this chart for electrical requirements:

Wire gauge and breaker size must meet all applicable provincial, state, local, and national electrical codes for your area. These are only guidelines that may apply to most installations. Some codes require you to have an electrical sub-panel, especially if the heater is not mounted within the line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load.

If your home is already equipped with a lot of electrical appliances, you may require a larger electrical service than the one recommended in the chart. The above chart contains only guidelines. Please consult with an electrician before placing an order.

Frequently Asked Questions ("FAQ")

Q1: How do I replace the heating element on the ECO 8?
A1. Replacing the heating element on the Ecosmart ECO8 tankless water heater is fairly simple. But since removing the water heater cover is necessary, and there is a risk of injury or death due to high voltage, Ecosmart recommends that a licensed electrician do the work. Here are the steps:

1. Disconnect power.
2. Remove cover.
3. Unscrew the two steel screws on the end of the element plug and remove the two wires.
4. Unscrew the element from the heating chamber. The ECO8 uses one element.
5. Tightly, securely screw in new elements and replace wires and cover.

The ECO 8 heating element is available for purchase here.

Q2: How do the temperature dial and display work?
A2: When water is flowing through this tankless heater, the digital display on the front of the unit shows the water heating temperature that you have set using the dial. To set the temperature, start by turning on any water faucet. The digital display will light up and give you the current temperature setting of the unit. To increase this setting, turn the control knob to "Increase" or "Decrease" your temperature setting. You can set the temperature at any level between 80°F (27°C) and 140°F (60°C). To change the digital display from Fahrenheit to Celsius, simply press the control knob for 3 seconds. Most people feel comfortable showering or bathing at a temperature between 98°F and 105°F (37°C to 41°C). We recommend that you set the output water temperature of your water heater at either 105°F or 110°F (approximately 41°C or 43°C). This will ensure you have adequate hot water to meet all of your household needs while also maximizing your available water flow rate, reducing the risk of scalding to children and the elderly, and increasing the energy savings you achieve.

Q3: Can I install the ECO 8 outdoors?
A3: Ecosmart tankless water heaters are designed for indoor installation. Installation outdoors is acceptable only if mounted an enclosure that protects it from dust, debris, rain, splashed water, insects, and direct sunlight. It must not be installed where it may be exposed to freezing temperatures. If any moisture is inside it when it freezes, the warranty is void.

Q4: How much can I save with ECOSMART's Tankless Water Heaters?
A4: The primary difference between savings associated with storage tank heaters compared to tankless heaters is the amount of energy and time consumed during operation. An electric tankless water heater consumes more energy compared to a tank heater during its use, but it consumes energy for a drastically shorter period of time. The result is a reduction in water heating costs by up to 60%.

The image below contains a visual representation of the concept mentioned above using data taken from independent third party testers. It shows how the storage tank heater keeps drawing power even after the need for hot water has long ceased. In this example, the tank heater used energy for 34.5 minutes just for a 10-minute shower. It also used a total of 2.5 kWh, in comparison to the ECO 27 which consumed just 1.6 kWh. The steadiness in the data represented about the ECO 27 is also an accurate indication of how precise the Self-Modulating Technology is, allowing for very minimal differences in energy consumption.

PSC (Product Safety Consulting, Inc.) is a product testing firm recognized internationally and accredited by several reputable organizations. PSC administered numerous tests that simulate daily hot water usage and then compared the energy consumption results between an ECO 27, the largest model available from ECOSMART, and a 40 gallon water heater from Rheem. Based on an average ten-minute shower consuming two gallons per minute, a 37% savings in energy consumption was confirmed with the ECO 27. This figure is based on usage comparison and does not take into account energy loss associated with Cycling Loss and Standby-by Loss which may be accountable for up to 20% energy loss. This loss included, the ECO 27 uses up to 57% less energy compared to a standard electric storage tank water heater.
