No. The black is 220, the red is 220, and the ground serves as the neutral.

the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.

Do you need ground to run a 240 vac water heater?

No, not really. The two hot legs can be opposite legs of a 120/240 V split phase power source. You still do need a protective earth ground, however, but the heater itself does not require a grounded neutral to run.
