Frequently Asked Questions ("FAQs")
Q1: In the table of specs above, it says that a 300 amp electrical panel is required. I was told 200 amps would be ok. Which is correct?
A1: The heater itself requires a maximum of 160 amps because it is wired to four 40 amp di-pole breakers. But your home has other electrical demands. Sum up the amperage of all the demands that will, by any chance, be simultaneously running). Add that to 160 amps. The total is how many amps the electrical panel needs to run the ECO 36.
Q2: What is the maximum output temperature?
A2: The maximum output temperature set at the factory is 140°F, 9KW per element. However, it is possible for it to be increased to 180°F. After removing the cover, at the very top of the jumper strip look for a jumper marked "180". After electric power is disconnected, place a jumper on these two pins. Once the power is restored, the unit will allow a setpoint of up to 180 degrees F. If the jumper is not there, then it can't be done with your version of the ECO 36.
Q3: How do I replace the heating elements on the ECO 36?
A3. Replacing the heating elements on the Ecosmart ECO36 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 the 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 ECO36 uses four elements, each screwed into its own heating chamber.
5. Tightly, securely screw in each new element and replace wires and cover.
The ECO 36 uses four heating elements which are available for purchase here.
