The French made Noirot is nice looking and has a life time warranty. Plus I understand it has a thick heating element which has a lower temperature so won't cause burnt smell.

But how does it save power cost when compares to other similar type of heaters? Say a Goldnair panel model. The sales people told me Noirot will cost me 27c per hour while others cost me more than 54c. She showed me a booklet to back up that point.

If it is that efficient then I think the 4X price is worthy. But how panel heaters have different efficiency?

Basic heaters (as opposed to heat pumps) are all 100% efficient. The only way it uses less power than another heater is by producing less heat.

The salesperson is full of it. Don't believe a word they say, they're either stupid, lying, or trying to trick you.

27c vs 54c means one is 1kW and the other is 2kW. Guess which one produces precisely twice as much heat (for precisely double the cost per hour).

It's not more efficient, it's just a lower power heater. It's like comparing a one bar heater with a 2 bar heater - of course one will cost more to run, it puts out more energy.

The only electric powered heaters that are more efficient is a heat pump - by approx a factor of 3.

It may be better engineered for some purposes and that may well make it more efficient for some purposes. That would not be hard compared to Goldaire.

I zoomed in on the picture but the text is unreadable. Is there a link for the product?

I made the image in the OP a link to the original so you can read now.

Nope. Plus now I have you in the same basket as that salesman... ;)

Would anyone like to buy a $3000 vacuum cleaner? Cleans hundreds of times better than some crappy Warehouse vac.

I understand where you are coming from, but you're wrong on this occasion.

Your formulation is based purely on electrical efficiency. In your formulation, a 2kw fan heater is exactly the same as a 2kw bar heater. For some purposes, heating of air in a large space quickly, the fan heater is more efficient at doing that. Then there are differences between fan heaters and volume capacity and volume to be heated etc.

As for the salesperson presenting kw consumption as relevant metric to compare efficiency of two heaters completely with you on that one. That sounds entirely deceptive. This is the kind of thing put in product selling guides in some markets.

I like to think of it as:

Efficiency - how good it as at converting electricity into heat

Effectiveness - how good it is at making you feel warm/warming your room

2.4 kW = 2.4 kW

$729 = ridiculous

Like Nick says, a fan or other technology can make a heater more effective for a given area, but doesn't increase the electrical efficiency. This one doesn't have a fan. It's just a convection heater.

The poster above says what makes it efficient is a thermostat. Just like the $20 oil heater that I bought from the warehouse 5 years ago has.

The accuracy of the thermostat could mean that if someone chooses 20 degrees, that accurate thermostat may perform as it should by heating the room.

Then, once the temp reaches 20 degrees, it turns off.

An inaccurate thermostat could mean that the room may be heated to 25 degrees prior to it turning off - meaning it is wasting electricity by heating the room for longer and to a higher temperature.

If the thermostat turns the unit off at 16 degrees, then that's an ineffective heater.

Yes the electrical efficiency does not change. That is my point also. All the same, you can have two different convection heaters and one is definitely better than the other.

The difference claimed by the salesperson, that's another story. It's almost certainly deceptive.

It may well be a good product. Like anything the amount you spend will depend on priorities. If it was that simple, everyone would have a $20 warehouse heater and be supremely happy with it.
