## Questions & Answers

**Q: Is it run with 2 phase or 3 phase breaker system ?**
A: This does not require three phase current.  Standard 240v current is all that's required.  You will need to install three 40 amp, 240v breakers and make three runs of #8 wire from your electrical box to the unit.  The reason for three is because the heater has three elements, each needing 40 amps.  Depending upon the flow demand and the inlet water temperature it will turn on one element, two, or all three.  This way it can match the heating to the demand.

**Q: Why would the light not go off?**
A: If the light is on even when the water is turned off the tankless water heater might be defective. was it installed by a professional?

**Q: Can this work in cold climates in New York**
A: Why not? Cold might present two problems: frozen pipes would affect any water system, and if the incoming water is too cold, the 27kw may not get the water that hot.

**Q: Will this unit work with well water?**
A: Hard water would probably clog it up eventually but as long as water pressure is enough I don’t see a problem

### ⭐⭐⭐⭐⭐ Works great
*by L***N on July 23, 2023*

It started off a little dicey, because it wouldn't work after installation. After calling the help number, we were informed about the possibility of cross polarized circuits...yep. THAT should be in the back page of "problem solving", but once corrected, it's AWESOME. Gets up to the set temperature within one minute!
