A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.
Single pole thermostats are used for 120 volt circuits. Double pole thermostats are used for 240 volt circuits.

Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
