I have been asked for ideas about a heater not working. (not been to look
yet). How are they normally connected

Each heater should be fed by a dedicated radial circuit from the
off-peak board (or the off-peak section of a combined board). The
fixed wiring should terminate in a switch near the heater, from
which heat resisting cable should go into the heater.

The protective device at the board may have operated. If there is
switched fused outlet instead of a switch then the fuse there may
have operated. The heater may also have overheated for some reason
(usually being obstructed) and needs to be reset.

Other than the smallest sizes such heaters have multiple elements,
so the failure of an element will not cause total failure (though it
may be that the elements have failed one by one).
