How about putting the nichrome wire inside the copper tube? it could be
stretched between two glass or ceramic supports at different heights on
the tube. If direct contact between the wire and the wax is undesirable
then you could put the wire inside a thin glass tube, even bend the
glass tube in an U shape.

I think with the wire inside the tube the response of the system would
be much faster and save a lot of energy. Even the tube could be of some
other material, perhaps plastic.


Best regards,

Isaac
