What is the difference between a double pole and a single pole thermostat?

Single pole thermostats break only one side of the power line to your heater and cannot be turned “off”. Therefore, power is continuous to the heater even if it is not running. The control knob will have a low temperature setting without an “off” position. Double pole thermostats break both sides of the power line; therefore all power to the heater is interrupted. The control knob will have an “off” position.
