I'm thinking about getting a tankless electric hot water heater. I've had problems with them in the past, they just don't give me the GPM at temperature that I like. I'd like about 200 degrees F at 10GPM. Is that too much to ask? I think I've found my heater:

How do you guys think that would do? I have access to 277D/480VAC and 400A distro panel. Sould be ok, right?

Yes the specs say it will work. but only if you have three phase 480 volts.
That means three seperate hot wires each out phase.
Or simply being allowed to use a triple breaker that takes up three slots.
Under NEC rules you must be able to disconnect all non grounded conductors. The oinly grounded conductor is the neutral wire.
277D sounds like 277 volt delta type transformer. This is three phase. So it is possible to have 480 volt three phase distribution.
You may also want to consider natural gas type tankless water heaters.

that's complicated to assert what you will unquestionably shop on the utilities, yet you may shop some thing. you will additionally shop some area. you will by no ability run out of warm water. and that they final longer than a tank water heater. $900 is truthfully the main inexpensive value for an put in tankless i've got ever heard - that's particularly under the cost of a incredible unit by making use of itself. observe that the greater effectual contraptions are from Noritz, Takagi, or Rinnai.

The temperature and volume problems are rectified using more than one heater.
Why can't you use a regular boiler? With this volume, you might as well have standing heated water, point in fact you may need pre-heated water to be able to achieve 200 degrees.

I have to agree with the last point that Steven made - Go with a natural gas unit. I have put a number of them in and one customer was very specific when she told me that her gas bills dropped dramatically once it was installed. The cost of NG vs. electric makes this real easy to recommend. All that being said, if cost is not an issue then please disregard this entirely!
