Replacing a baseboard heater

Hi there. First of all, I know next to nothing about wiring. That said, here's my problem:
I recently purchased a 240v, 1500w baseboard heater to replace the one in my (1996) home that had become fouled with a melted plastic toy on the element. Anyway, I assumed replacement would be simply disconnecting the old one and reconnection the new one.
The new heater has 2 wires, this would be easy!
Unfortunately the old heater has 2 wires for the power, and another 2 which I assume are for the thermostat on the wall. Is there a way that I can make this work? Any help would be greatly appreciated. Thanks in advance.
