Question

A fuse wire cannot be used as a heating element.why?

Answer 1

Because once it heated up, it would blow.

Answer 2

fuse wires are designed to go into thermal runaway, as they heat up their resistance will increase and they will rapidly get to the point of melting or vaporizing.

Answer 3

Fuse wires are design to melt and break when they exceed their design specification.  For effective heating, you would exceed the rating of most common fuses, so it would melt and break the electrical contact and no longer heat!
