I thought that was "on paper" due to having a lower water content?

Water volume makes no difference to power output vs delta-T.

It might aid with overall system response, if you reduce overall water
volume a lot as a result, but the power output is valid when the system
is in steady state (radiator, not room which is obviously heating).
