baseboard heater - 2 cables
I installed a 120v replacement baseboard heater/thermostat last year. I wired it into one set of wires from one cable and it worked for a few months and stopped working. I bought a new 240v heater/thermostat but this wiring is odd. IDK if it is connected to another heater, and it is not in my home, so I can't test it now but I thought that both sets were live. I know I'll need to drive over there and test it again, but for now, any ideas on wiring this?

Check the voltage at the wiring.
The second wire may go to a wall thermostat.
Sounds like you are doing a lot of guessing here. Wiring is not something to guess about unless you want to make work for the fire department.

fyi, turns out one cable is hot and the other isn't, and it is wired to a 240v breaker on the panel (B hot, W hot , ground, no neutral). Soooooo, it is a 240v circuit (heater) and the power continues to another heater. The 120v heater that was installed burned out after a few months from the 240v circuit.

Be thankful it was the heater that burned out and not your house! You cannot get 120 volts from a 240 volt circuit unless you use the bare grounding conductor as a current carrying neutral which apparently is what has happened.
