Bill,
There must be there a way of balancing/
equalising the pressures and flow through
parallel radiators with the use of regulators or
some such auto or pre-set resistors or balance tubes etc.

Maybe -- maybe not. The hydraulic resistance for the two flow paths may
be different, then the flows will not be the same.
I have mine plumbed parallel, and took pains to make all hose connections
equal length. We will see when I get it started whether it works as
planned.
