If i'm bored I sometimes put a shopping channel on to amuse me in the background.
Currently Ideal World are trying to convince me to sack off my CH and buy 2kw plug in rads instead, at a mere £200 each, but they are ceramic which apparently pluck free energy out of nowhere!
They probably are an internal use heat pumps - put 2kWh in and it sucks the equivalent of 8kWh of heat out of the room.
It's a ceramic radiator, they are claiming you plug it in for 3 minutes, switch it off, it keeps getting hotter and keeps kicking out heat to heat a 25 sq metre room.
Who is to blame, scummy sellers or people too silly to pay attention in physics?
And pumps this heat where? Suck 8kWh from the room, pump back it into the room, spending 2kWh electricity in the process. Result: 2kWh more heat in the room. ie that's just a costly way to do electric heating.

It isn't a crime to be thick but fraud is.
They'd be genuinely better off spending the money on a gambling site!
As a teacher of mine said at school, most scientists know something about art, but few artists understand much about science.
Perhaps it has graphene elements for increased efficiency.
There are loads of these adverts, so they must be selling this crap.
That may be true in as much as (a) the surface temperature continues to increase if it is switched off after 3 minutes (a result of the combination of thermal capacity and conductivity of the product) and (b) it will heat the room (as the energy has nowhere else to go). IOW no actual lies for the ASA - let alone the law - to bite on.
Blimey, that is more expensive than storage heaters. I have some old Dimplex ones and they are fine, but two have an issue which could be a diy fix. The knob that operates the louver bits to let the heat out have stiffened to a degree that they stick. One is still OK, If I turn these off is there a way inside and if so I assume they need some kind of lubrication? Brian
I don't know how they get away with such claims..
+1 People sometimes deserve what they get..
Except the scam artists..
Because most are paying much higher heating costs.
That doesn't follow.
School is partly there to give people the tools to avoid being scammed. If they don't pay attention, they have themselves to blame. I still think the ads should be shut down.

This is my theory.
They work by converting some of the ceramic into energy . The ceramic is slightly radioactive - similar to that once found in pottery glaze.
The Mass -Energy equivalence principle says that when energy is lost in chemical reactions, nuclear reactions, and other energy transformations, the system will also lose a corresponding amount of mass.
The energy, and mass, can be released to the environment as radiant energy, such as light, or as thermal energy. The principle is fundamental to many fields of physics, including nuclear, particle physics and some forms of ceramic heaters.
Delta E = Delta M*c^2
0.1 micro-gram of ceramic will produce roughly 2.5kW -hr of heat, but you don't want to run it as hard as that in order to avoid thermal runaway.HTH.

Spend it in a brothel
I need some breathable wall paint, and picked up some colour charts yesterday. One of them contains graphene, the toughest substance known.
But hang on a moment, isn't it black?

SSSHHH! 'differently colored' PLEASE.
