Easy way to tell (maybe) is to open it up and see if it has a conventional small 60 Hz transformer to power its internal 12 V electronics. If so, 240 VAC will likely overvoltage those low voltage circuits (operating at 12 V). On the other hand, if it does not have a small 12 v transformer, then

The cheapest DIY ground-source heating is to hang an old Air Conditioner from the floor joists of a popular central room in the house and cut a hole in the floor to connect the hot side of the AC to the room. The cold side remains in the basement air. A 10,000 BTU AC unit becomes a 20,000 BTu
