No, This unit does not require an expansion tank unless local code requires one.
This is a 240 Volt unit
That would be a good questions for your electrician. Usually it is not a problem. They can also do a "Load Calculation" to tell you how many and what size breakers you can install in your panel. This will determine which water heater you can purchase too. If you have any questions, please feel free to call our Technical Support Department at 1-800-582-8423 Ext 6 Thank you.
Yes, the unit must be protected from the rain and critters. The unit can not freeze or it will damage the unit. Do everything you can with insulation or any means to not have the unit freeze. If you have any further questions, please feel free to call our Technical Support Department at 1-800-582-8423 Ext 6. Thank you!
On average, doing a flush once a year is sufficient. However, if you have a very high level of mineral in the water, twice a year may be necessary. If you have any further questions, please feel free to call our Technical Support Department at 1-800-582-8423 ext 6. Thank you.
Energy Star offers no category for tankless electric water heaters so there can be no certification. Their "reasoning" is that at 99-100% efficiency for tankless electric there can be no improvement in efficiency for the category. That makes little sense to me as it doesn't help people decide what is efficient or not.
Coming late with response, most tankless have similar requirements. If this is the way you want to go, get an electrician to provide you with the information you need. It is most likely that you have the capacity.
No, it does not require one.
Yes it will. Since it is a non-continuous load, you can run 8/2 wire and be just fine.
