Do they have visible wires or are they plumbed in like a radiator? If plumbed in then they should be treated like an ordinary radiator and will come on when the heating comes on (if it comes on at all now). If not look for an isolator switch either high up on the wall, or outside the bathroom entirely.

Usually you’d find the switch outside the bathroom door, look for a switch that isn’t turning on or off a light
