I have a dimplex heater 2000w 240v(going to be adding a second of the same wattage on the same line) in my garage with a honeywell double pole manual thermostat(T410B1004). They gave me 14-2 wire and said it would work. Plus "heater" wire(brown cover, two solid copper wires red and white). They also gave me a double pole beaker that has two swiches that move together, they each say 15 amp) I have the 14-2 wire from the panel to the thermostst and the "heater" wire from the thermostat to the heater. I have gotten mixed advice about how to wire the thermostat (l1,l2,t1,t1) and have tried more than one way but I can't get heat. I'm getting power to the heater but no heat. Can anyone tell me if any or all of these items are the correct ones for this application, and how the wiring needs to be hooked up. Thank you so much!

You need an experanced electricion to look your situation over, I wouldn`t run the 2 heaters on the same line,and I wouldn`t use the small 14 gauge wire, but I`m not there to look over what you are trying to do
There should be a plate somewhere on heater or in the install manual that tell you how many amps the heater will draw at max ,this will tell you the size breaker you need,, goodluck and be careful, electric safety is very important
