Health Care for expats

Good evening,
Can anyone tell me about health coverage for expats. I am a US citizen with Irish citizenship also, and i may be moving to Vienna.  I wouldn't be working right away.  Would i be able to get free healthcare in Austria, or would i need to get coverage through my significant other's employer?
Thanks!
