First of all, I'm not an electrician and don't expect to do the connection in the breaker panel. I just want to install everything and then call an electrician.

So I want to install two baseboards in parallel with one T-Stat in the basement of an old house.

The following setup gives each baseboards 240V but they don't heat: baseboards are 1000W each

1) 240V runs from a 15A breaker to a Double-pole Tsat
2) Runs out to junction box
3) Out of junction box, one cable to electric baseboard 1 and one cable to electric baseboard 2

If I install them in a serial setup, everything is ok but they do not heat as full as they should do.

Thank you folks
