Then you must thing a rad has hot water in, room temperature water out...


Nope.
You seem to thick pipework to & from a radiator emits no heat...
Especially in draughty cellars..

You seem to be trying to tell me a length of copper pipe is as
good at heating a room as a radiator...

Dunno why you are arguing over a topic in which your knowledge is total zero.
Did you have any education at all?


Ooh dear, sounds like a losers argument hazza?

Indeed ;-)

And in the case of radiators, the input is heat in the water and the output to the room is heat too. There is no conversion process, no other inputs or outputs, and no loss.


There's also space efficient - heat output/cm3.

Space efficiency, material efficiency, cost efficiency etc. But this thread is about efficiency, which is heat out over heat in.

If you don't want heat loss from the pipework, insulate it.

How you you think underfloor heating works?

It was best missed as it added nothing.

When asking for technical advice, it helps to know what technical terms
mean. If you don't, best not to use them.

Pfft! Oh dear the science has left the building I see :-D
just the handwavy "armchair expert" bluster remains ;-)

I already have the practical #real world# answer I was after,
shortly after asking, without any of your & others pedantic
attempts to sound knowledgeable. Theory vs practice...


Watching pedants squirm was an added "bonus" :-)

Only one squirming was you. Everyone else seems to understand what
efficiency means.

You obviously subscribe to the Humpty Dumpty principle:-


”When I use a word,‘ Humpty Dumpty said in rather a scornful tone, �it
means just what I choose it to mean ˜ neither more nor less.‘

‘The question is,‘ said Alice, �whether you can make words mean so many
different things.‘

‘The question is,‘ said Humpty Dumpty, �which is to be master ˜ that‘s
all.•
