This can be somewhat difficult if a lot more water is going through

than another.

Then don't use a condensing boiler.

These days you don't get much choice.

Worst case scenario it doesn't condense, so you get less efficiency?

And why does all the water going to one radiator cause a problem?

Cos all the others are cold, perhaps?

A problem for the condensing boiler I meant.
