The heaters are 240v so both the black & white wires coming from the breaker panel are 120v to ground. That's why there's two breakers tied together for each circuit. If either side shorts out to ground both hot wires get tripped. These can be converted to 120v by switching the white wire of the circuit from a circuit breaker to the neutral bar in the breaker panel.
In doing the conversion probably the worst thing you would end up with, if you have wall thermostats, are blank covers on the outlet boxes where the thermostats are.
