cold temps and water heater?
How cold and for how long before you think about draining your water heater? Been having temps in low 20's from sundown to sun up and getting concerned.

If you have been having sustained temps in the low 20's F, then it may already be too late. It takes one gallon of water 4 hours to freeze at 32 degrees and expands 9%. Have you already drained the rest of the system? Pipes, pumps, strainers, unions and fixtures will crack first.
If your plan is to fire it up, I would wait around a while to look for leaks. You may end up thawing it, revealing a leak and subsequently heating air if left alone.
