Are they not the same.
Are the two not one and the same?
The Thyrsitor chops the waveform (assuming it is phase angle control) thereby reducing the power dissipated in the heater and consequently reducing the load on the genny.
I am however not sure if the thyristor unit on Ebay is phase angle or burst firing. Phase angle would be the best choice in terms of a steady load on the genny.
The alternative is to use a series resistor of about 16 ohms and rated to 200 watts
Added. Just went to the toilet and thought about this some more. Burst firing would be a "NO NO" as assuming the unit was set up for 50%, the thyristor would be fully on for (say 2 secs) then off for (say 2 secs) resulting in the genny being subject to an on off load. Had this problem on 500kw burst firing control system for a furnace and our 800kw Rolls Royce genny did not like the load at all. Has to be a phase angle device to give the genny a steady load.
