Surely though if less heat is lost then where is it going to?

It isnt going anywhere, less heat is extracted from the circulating water.

It may take longer but in the end it will get away,

Nope.

and all tat should happen is that the boiler will not be needed to be on
as much,

Yes.

but then some areas of the house might be colder than others.

And the room wont be heated as well.

What is this nonsense, heat is dissipated by radiation, convection or
conduction so how come efficiency becomes a problem.

For conventional central heating radiators most heat-loss is through
convection. Air is a poor conductor.

It seems there is less overall air flow for a tall radiator than long for
a radiator with the same area and construction.

So hardly nonsense.
