suggests the optimum aspect ratio of the radiator is highly
dependent on wall height.

It doesnt even say that.

I'm sorry if you can't understand the paper.

Even that is unclear.

The paper makes it clear.

But not for the horizontal and vertical radiators
we are discussing, they dont even consider those.

Read the paper again.

No need.

It isnt even relevant, its discussing the wall
treatment and the gap between the radiator
and the wall which isnt where most of the
heat from the radiator gets into the room.

And a function of radiator aspect ratio, ie height and width of radiator.

Even your earlier post whinged

More of your bare faced lies. I actually
rubbed you stupid nose in that fact.

that they only considered aspect ratios of 0.5 to 2.

Thats not the vertical radiators we are discussing
which are well outside that range.

So an agreement that efficacy in terms of aspect ration is dependent
on a number of circumstances,

Nope, what matters is the main effect, the vertical distance
the cold air moves over with both types of radiator. Thats
much worse with vertical radiators and is the reason they
dont work as well as horizontal radiators do.

The paper gives instances where that's not the case.

and that a "very wide horizontal radiator" wouldn't necessarily "work
better as far as heating the air is concerned".

For a completely different reason, the difference
in the surface temp at each end of the radiator.

So an admission there is an optimum aspect ratio, and wider is not
necessarily better.

A very wide horizontal radiator would work better as far as
heating the air is concerned.

And there you go again, flagrantly dishonestly stripping
that para out of the context, your trademark.

Did you not say that? Or have you simply forgotten you said it?

Not in all cases, as demonstrated by the paper in real home
situations.

Says he carefully and flagrantly dishonestly
snipping what I said is the reason for that.

Is that agreement?

You never could bull**** your way out of a wet paper bag.

reams of your flagrantly dishonest **** and lies flushed where it belongs
