Hi All,
Here is a video and a diagram with some claims made. It should be noted in the video I state the picture is wrong, referring to the temperature of the welding rod, in actuality the video and the diagram are both wrong... the actual temperatures that the welding rod reached are closer to 700-800*F range in the 40 seconds allotted for the test, in the video, while using a 12 volt battery as a power source and 1.3 amps of current draw for the active circuit.
Bedini for heat generation. - YouTube
In conjunction with the welding rod heat... It should also be noted that the coil and the transistor also put out much heat while the circuit is running and this waste heat could easily be harvested and or collected and used for ones heating needs as well.
So in general this system puts out a large amount of heat while still charging a secondary battery bank.

Dave, greetings
Interesting to evaluate heating efficiency with pulse vs sine in resonance.
Traditionally as you know eddy sine current is shallow at 400 kHz and deeper at 30 kHz.
Since pulse measurements are controversial you may have a calometric
method. Possibly a thin brass tube.
water at room temp with a flow rate of 40 seconds for so many CC water.
i think the shallow eddy with thin brass tube thermal conductivity might suffice
to show less watts according to your finding
giving a higher temperature outcome. Others would need to prove that
the same experiment using sine and there choice of coil and electric
could produce same. Looks like you might win.
The older induction goals may have been studied to
heat massive iron and they wanted coil longevity as a goal.
seems to me I recall 72 kHz being one such derivation.
It is interesting to see where this will go for measuring pulse and heat.
Nice to learn you are getting better heating efficiency.
