Is there a dead-front GFCI available that will work at 240 volts?
The proposed application is a 240-volt-only, 2-wire load in an older house where installing one in the fusebox is not an option.

Why are you concerned about an existing installation?
Is there an EG to the heater?
Instead of a deadfront GFCI, would you consider a 240V thermostat with built in GFCI protection?
Here is an example intended for floor warming, but perhaps it points you in the right direction:

These are built for 120 or 240V operation, have built in GFCI protection, and are intended for heaters.
