at least one axially elongate jacket element defining an axially elongate jacket block having first and second lengthwise ends;
a plurality of longitudinal bores or channels extending internally through the jacket block and being open at each of the respective first and second lengthwise ends;
at least one heating element extending axially through the bores or channels, the at least one heating element and the jacket block forming a heating assembly;
