Zinc Anode for heater

I was thinking about getting a used Hayward or Raypak pool heater that is only copper for my saltwater above ground. Will a zinc anode work if it connected to the pool heater's grounding bolt but NOT to any ground? I don't think I have a grounding option.

I thought about getting a grounding rod, but even at 4 ft I don't think I could get it that far into the ground since often I can't even get an 8' stake into the ground in my rocky backyard.
