Yes, this is from Electrorad - part of their website which does indeed show their testing method -quotes the test conditions and also states that it was conducted by an independant UKAS acccredited testing laboratory.

So what? There is NO CONTROL. All the results shows is the heat loss from the room is very low.

It's easy because it's true.

You have many years of experience, yet you are telling us that thermodynamics is correct in theory, but when applied in practice to these radiators goes out the window??

Wouldn't a manufacturer of these radiators have gone to ground many years ago if it was just a [TEXT DELETED BY FORUM TEAM]? Some of these have been around for 50 years now. I'm sure some of them are dubious in some respects, but the same could be said for most companies.

Oh please, if you seriously believe that you are a complete fool.

Moneysaverbloke, you are arguing that 2+2=5. Don't you realise that (obviously not)? Companies like the one discussed who make claims which go against physics are kept afloat due to people like you who - and I don't mean this disrespectufully but just as a matter of fact - don't appear to have had even the most basic of scientific education - that's why they have lasted 50 years.

Anyhow - no one is trying to stop you buying them - go buy a houseful if you think they can heat your house cheaper than a couple of lightbulbs which would supply exactly the same amount of heat as the test, and let us know if the heat is better 'quality', or more 'even' or better in some other way, and what your bills are like during the winter.

Anyhow, I've got this fantastic device which quadruples the mpg of a car, pp me and I'll tell you all about it.

There are far too many variables involved. There are good heaters, and there are poor ones - both may use SIMILAR amounts of power, but they don't both produce the same results. There are also different electric heating methods. Some work in particular environments, others don't.

Well you at least are consistent in the rubbish you spout!

I assume you work for the firm as a salesman? The nonsense you post indicates you have no technical knowledge.

Let me state unequivocally that if any heater ‘uses the same amount of power’ then it produces the same amount of heat. You can measure that heat in British Thermal Units(BTu), Calories or Joules and it doesn’t matter as the figure will be exactly the same.

If anyone wants that heat released really quickly, then a £10 fan heater will be fine.

If anyone wants slow release, with some residual heat, then a £20 oil filled radiator will do the job.

If anyone wants to have a fancy control system with timers and remote control, then buy some sockets for a few pounds – the heaters have thermostats fitted.

If anyone really wants to pay £hundreds or £thousands for electrical heating systems with extravagant and misleading claims that imply their heaters produce more heat because they are filled with some magic ingredient, or coated with some special substance, then there are loads of firms who will take your money!

Who do you work for again?

P.S.
Trying to promote firms with boguis claims on MSE will backfire because a Google will produce threads like this. MSE is about Money Saving not money making for firms like yours.

I understood from these quotes in your posts you were a heating engineer:

As an ex heating engineer i fitted lots of systems which gave very diferent results

I can say this as somebody who has installed various types of electric heating systems over many years.

These were some other ‘gems’ you posted:

All electrical heating does not cost the same to run though. A bar heater, convector heater, or other cheap panel or bulb heater may often consume it's full output capacity all of the time that it's used, other more sophisticated electric radiators can maintain the same level of heat but only use about a third of the electricity.

I would would not EVER go and buy a £20 convector heater because I know for a fact that it will not give any decent quality warmth, in fact, it will literally burn the air around it, and not put any warmth further than a couple of meters. It will also cost a fortune to use while not performing.

Would you care to elaborate how 'sophisticated electrical radiators' can maintain the same level of heat consuming a third of the electricity of less sophisticated electrical heaters?
Use, BTu, calories or Joules for the heat output if you wish.
P.S.
As you asked, I am a Chartered Electrical Engineer. However the facts about heating some of have expressed in this thread would be known by every physics GCE O level student.

I've looked. I don't see it. When I say methodology, I mean a detailed description of the testing environment and equipment used. Like you would find in a scientific study published in a journal. Feel free to point me in the exact direction of the methodology you are referring to.

Here's some free advice from a physicist.

If this "study" really has shown the things you/electrorad claim it does, the "scientists" who did the study should write it up properly and publish in a peer-reviewed journal. You/they will make a fortune, and the paper will be feted for ever.

Any particular reason that hasn't already been done?

Wouldn't a radiator be more efficient than a fan heater due to the fact that some of the power used in a fan heater is consumed to rotate the fan, which generates no heat, whereas a radiator (or other heater with no moving parts) converts 100% of the power for heating?

No - they both give the same heat for the same electricity.

The fan heater uses some of the energy to move the air, but when the air slows, the energy which moved it is given up as heat too.

You could argue that heaters are pretty poor users of energy in that you always have the option of doing something useful with the energy before it ends up as heat. For example, if you want 300w of heating, instead of tuning on a 300w heater you could instead turn on the 300w xbox360 and play games - you'd still get the 300w of heating plus you play for free.

This is also the reason why using energy efficient light bulbs doesn't save the costs usually quoted. If you have a 100w bulb, and thermostatically controlled central heating, then you'll use 100w less on your heating. If you use a 7w energy efficient bulb, then you'll use 93w more power to heat your house than if you had a 100w bulb. (I'm not saying energy efficient bulbs shouldn't be used, just tht the saings are not as much as generally thought - the heat they produce has to be offset from the savings).

In this forum we obey the laws of thermodynamics! Next time you use a fan feel the motor, it'll be warm - 100% of the energy used to rotate the fan end up as heat through friction.

My gosh. So, next time I feel chilly, I can just switch on my 2400w steam iron. My lounge will be heated just as affectively as when I use my 2400w radiator (measuring about 1400x600)

Wish I had known that in my days as a heating engineer (ex heating engineer as I said) Incidentally, I have posted about the results of test figures from at least two different firms, so if I am here to promote my own business as Cardew seems to think, I'm not very good at it am I?!

Anyway, I'm cold. Must go and switch the toaster on.
