".... 4 fois plus de volumen traite'.."

------------------------------------------------------Reading the hunderts of different heating methods patents/-applications we will have to find for ourself an own measure leveling, cause there is not a real comparison standart.Example : Gricourt 1500 W ~ 75x5W in ~ Leo Peron 1500 W~ 375 W in ~ Frank Sibert 3000 W ~ 660 W in orWilliam Kling 11000 BTU=3100W ~ 610 W in
We have to calculate, in virtual manner the building r-value and the local climate zone and standerizise the patents/ utility models given examples:Richard Cooper infrared heatpanel, example Florida, 280 W electric for 14 sqm floor space with some interior walls heated~ the upper bulb heater ( Gricourt, Peron,...)electric power consume +/- 400 Wh/ 20 sqm.
Gerhard Beier heater : 80 W (controler regulated) infrared graphite panel for 20sqm floor, normal insulated house from the seventhies. - Charles Souders: 600 W(6x100 W bulbs) for the total US-location house, sqft ? Location ?

Between wet and dry air there is the potential from enthalpie gains,dehumidifier effect.And there is probably also a thermo- dynamic heat content and power need difference between 5°C-20°C and
0°C-20°C, as written in the FUJITSU heat pump webpage explication: 5 degrees difference but 100% more power need to heat to the same 20°C warm sphere.
Physics, physiolgy and psychology are here important, beginning with standing/moving  and wet/dry air related to open/enclosed human joung/old body ! Sense

To show the written difference given per sqm heat floor :Lefevre (Gricourt citing documents) 60 W electric power per sqm Beier                                                          4 W electric power per sqm

Another question - comfort - related :for a f.e. 20sqm room is it better/worser to use a 1500 W or a 375W heater when outside there is 0°C and I wish to get the room - fast- 21°C warm ! THERMOSTATE,on/off heat regulation or automatic 500W/1000W/1500W

Hi all, have been testing the heater.
Last night it was 32 F. outside and the room temperature was 71 F.
The space heater was able to raise the temperature to 74 F.

The heater draws around 300 watts.
I measured the room size, it is 300 square feet in area and again, this room has high thermal losses.
It has 3 large skylights, 3 larger windows, 3 smaller windows, window air conditioner in place still, 1 lossy door with large glass panel and a vaulted celing.
So to me, this heater seems quite effective and efficient.
Positive, Helpful questions or comments preferred.

Here's a picture of the 32 - 100 watt bulb panel.https://ibb.co/bW35DV

Congratulations, you are doing real experiments. I hope you have time to alternate 24 hours with your new heater and 24 hours with an old fashioned type.

Hi iflewmyown, thanks for the positive reply.
I don't have an old fashioned heater or store bought heater that uses only 300 watts, I have one that goes down to 600 watts, oil filled type.

What would you suggest i use to compare results with this french heater device.

I think that I would use any power line heater that has a thermostat. I would attach a clock that is run by the power line parallel to the element so that it would record the hours and minutes that the element runs. With a little fiddling you should be able to determine what setting will keep the room the same temp. and then multiply watts times hours. This will give you a crude comparison to start with. Or use 3 100 watt bulbs buried upside down in a bucket of sand to hide the light. Good luck.
