storage heaters

We have a number of storage heaters in our office, all on the same circuit (with seperation for convectors/fans and the heaters)
Two of the heaters do not work.
One has no fuse at the wall switch and a single wall switch.
The other, more important one has two wall switches, one for the heater and one for the convector, they are both switched on, the convector comes on but the heater is not working.
Is there likely to be a simple fuse inside I can change?
Thanks
David

Some of the older storage heaters were fitted with a lead thermal fuse, designed to melt if the temperature was exceeded. If this is the problem, you might be able to pinch one from one of the unused heaters. The problem could also be the 'heat charge' thermostat if one is fitted. This turns the supply off once the heater achieves a set temperature and should be closed at room temperature.
A final possibility is a break in the heating coil itself. Replacing this involves the messy task of removing all of the bricks inside the unit.
