Advantages

Low cost - essentially the cost of a $10 kiln heating element, and balance for refractory material and steel for case and legs.

Connect 2 heating elements by threading around a threaded rod - 3:30
1.5 meters long works for 250V - 3:40
Resistance in his case - 33 Ohm when cold - 3:45
Fire Bricks - 5:20. Note CEBs work well as fire bricks per results from Hydronic Stove, and results would probably improve if we used perlite. This would be a good product.

Kiln Heating Element - $10 - [1]
Clay graphite crucible - 10kg for $40 - [2]
Make your own graphite crucibles - flake graphite - 25 cents/lb for ton quantities. Or 16 lb (1 gal) for $45 [3]
