Not in the least. Many modulate on the flow temp (maintain a constant

It will still not have the opportunity to operate at the low
temperatures possible with a direct connection to the radiator load
and it will also cycle.

I've made the point, it is correct for the scenario described
(modulating, condensing boiler) and I am not going to repeat it.

That's good, it is wrong.
