Exclamation Under tile electric heating matt on bathroom circuit

Moving the bathroom closer to tiling and we're considering adding an electric floor warming system under the tile. The bathroom currently has a dedicated 20A circuit with 5 recessed lights, an exhaust fan, and one receptacle. Calculated wattage is something like 600W. The floor heating system adds about 240, so we're well below maxing out the circuit.

By national code, can the matt be added to the existing circuit or does it require a dedicated additional circuit?

Thanks guys!

Just be aware that doing so makes the breaker more prone to tripping,especially when using a high load like a blow dryer.
