I am about to replace an electric baseboard heater and the wall mounted thermostat. The thermostat that is there now is a single pole. My new one is a double pole, I understand the difference between them, but can I use the existing wires to install the new double pole, and if so, how is it done.
You will only be using 1 pole of this double pole t-stat. It's very important that the new stat has an electrical rating comperable with your new baseboard. 2 poles are actually 2 circuits going to different loads. Since you are only using 1 load, you use 1 set of contacts or one pole. Leave the other blank. 2 wires should be all that's to be connected. If you are using 220 vac, chances are that one leg was hot and the other going across the old t-stat made the circuit when needed. It would be a good idea to call an HVAC contractor to either walk you through on the phone or to visit you and show you how it's done.
