On the one hand - If you have an electric BB heater with a built-in t-stat, it will be single pole and one side of the heater will always be hot unless the double-pole breaker is off.
On the other hand, if you wire in a remote wall-mounted T-stat the code dictates it be 220v and disconnect both conductors when in the "off" position. Still, while in normal operation one leg will always be "hot" with the other leg controlled thermostatically. Only dialing to the "off" position disconnects both legs from the heater.
