HW heater and freezing.
Considering the hw heater is enclosed and probably insulated, how cold must it be for the heater to be damaged due to freezing?

Depends on time, temperature and wind chill (wind speed and direction) unless the water is already frozen then you can, for all practical purposes, drop the wind chill factor. :B
Our water heater has NO insulation to the outside air temperatures, just a metal vented door with a R rating of ZERO.
