Simplistic put down!!
My friend would say, so, you have a heater connected, wind gust, higher speed, heater will draw more current, more load automatically, so where's the problem.

- View Sourceyour statement is correct, i concur.
thanks for reminding me the neg. terminal produces the H2
the hho i spoke of was in respect of the systems where both + and - are in the same vessle. thanks for the input
