That is true,

You got that right. Now let's see what else he says....

provided that the heating system
has been designed/modified for
a condensing boiler.

Oh my God what tripe. A condensing boiler will always be more efficient
than a non-condensing boiler, even when not condensing, because the heat
exchanger is bigger.

An condensing boiler can give great efficiencies if the system around it is
engineered to take advantage of it: larger rads blanced to 60-40C, etc.

Beware of bull**** from manufacturers.
