Convection heaters send hot air upwards. Their grills / fins might change that slightly, but I'd be very surprised if it did much.

Charlatans preying on the ignorant. No doubt about it.

"Energy Effiecnt <sp>

Even after years of functioning it maintains your desired temperature within 0.1 degree Celsius".

Whereabouts is that measured? What about hysteresis?

What a load of old cobblers

If you want something similar I would look at the Dimplex ones, made in Norway but far cheaper

We got this one last year for our bedroom. Paid $285 as Briscoes were having a sale (shock horror)!

Throws out heat like nobody's business, so you generally don't need to have it on for very long. Takes up far less space wall mounted.

I wanted a 2KW one and this was one of the nicest looking ones I could find. Also has a fan that can be optionally turned on, but we never use it as it heats the bedroom so quickly without it (plus the fan is a little noisy - but probably no more than any other fan heater).

Note: The actual unit doesn't have the giant "Slim Style" writing on the side that is shown in the picture.

EDIT: Specs say it is 5mm slimmer than the Noirot too.

Paul, it says it has "HI-FI TECHNOLOGY". Does that mean it sounds good??

I'm pretty sure that's useless marketing people trying to come with a cool sounding way to say "it also has a fan".

Ironically, no fan is ever going to make a convection heater sound good. Fan off - essentially inaudible, fan on - whirring fan noise.

Stupid marketing aside, it is a good heater.

I reckon they're hoping to make the panel heater replace the oil column heaters as the new fabled "more efficient than the others" heater.

I have helped a few people diagnose bill shock (where in the first month of winter their power bills trebled) and the reaction is always "but oil column heaters are more efficient". The are ineffective, which means it is easy to forget they're running and also users are disinclined to turn them off when they go out, which means more power used.

Prudent flatmates don't let flatmates use oil column heaters.

Other bad fables include "it's cheaper to keep a house warm than warm it up".

That's my favourite - applies equally to spa pools

And also applies to hot water cylinders.

As for the heater in the OP, It is probably the one which justifies the BS claim by saying that it stores some heat in a thermal mass, so the element is only on for 1/2 the time. But the heater releases heat continuously.

Of course that doesn't change the fact already mentioned that 1KW in = 1KW out.

Some more dodgy marketing I have seen, was a test comparing an oil column heater to a convention heater. Which was turn the heater on in a cold room, measure time taken and power consumption to warm room to set temp. The expensive convection heater warmed the room quicker for less power usage. But only because it's thermal mass was lower than the thermal mass of the oil column heater. So the BS conclusion of the test is that you should spend heaps on this overpriced convection heater.

Yet if the convection heater had been put up against a $20 fan heater in the same test, the fan heater would have won. As it's thermal mass is virtually 0.

More entertaining marketing for Noirot:

Otago Daily Times: The heater is ideally suited to smaller rooms such as hallways, bedrooms or in a bathroom because of its double insulation design. Mr Feron is impressed that the Noirot heater offers "twice the wattage" of some energy efficient heating competitors.

But wait, there's more..

I think that the EECA should put mandatory energy efficiency star labelling on resistance heaters. Except that they should all be labelled as only 1 star efficient, no matter what brand or type of heater it is. It would immediately put an end to all of this marketing BS around electric heaters. It would cost almost nothing to implement as well, as no efficiency testing would be needed of each heater model.

Although it seems a bit rough that 100% efficiency = 1 star

I chose 100% efficiency + 1 star so that when people compare resistance heaters to heatpumps, It will make it really obvious that a heatpump will put out more heat compared to a resistance heater. for the same electricity usage. Also for some specialised heatpump applications. (Air to hot water heatpump when it is -10deg outside as an example) The heatpump might only have a COP of 1.5 or so. But would still be more efficient that a resistance heater.

So you would want to avoid the situation of a heatpump having a lower star rating than a resistance heater. Unless the heatpump happens to have a COP of less than 1.

Also it would allow for dehumidifiers to have star ratings of slightly more than 1. Due to latent heat of water vapour being condensed into liquid water releasing extra heat. You get 0.6KW/Hr of free heat for every litre of water that your dehumidifier collects. So for situations where you only want a low wattage heater, a dehumidifier if often a far better choice. As you get more heat output for the same power usage, plus the benefits of less dampness.
