I have two Unidare night storage heaters -both have recently stopped working -maybe someone covered then with clothing when I wasn't around.
Power goes in but none reaches the elements. I can't find internal fuse, unlike Creda ones. I understand the basics, but where is the possible fault. I notice there is an internal thermostat but where is the fuse system. HELP PLEASE.

If it is the WMS724N, WMS718N, WMS712N or WMS706N, it does not have a fuse, but it does have a thermal cutout. To fix, first switch off all fuse boxes / consumer units that run the storage heaters. Second, switch off the switch next to the heater to which the flex runs. Remove the two shiny self tapping screws at the bottom of the front cover, then remove the cover by raising the bottom edge and lifting up, holding the back panel down. Remove the two black self tappers in the top of the case, these are recessed down about 1cm. Use a magnetised phillips screwdriver to grab these, and prevent them falling in. Remove this top cover. You can now see the controls. Hinge the sheet metal cover over to the left. There is a small thermal trip at the front of the left hand control. With a finger nail, push it to the other side gently. If it clicks, you have reset it and the heater should work.
