I recently installed two 240v baseboards in series with a 240v double-pole
wall thermostat. Today I saw a 240v heater that says it uses a single-pole TS.
I'm doing the same thing in another room and want to know is that possible?

Thanks
 
A double pole shuts off both wires while single pole turn off one. In other words with a single pole the power is always at the heater and not safe to work on evan when the thermastat is turned off.
