This is absolute nonsense. The heat transfer rate to air has nothing to do with the overall efficiency.

Hi memoryman, thanks for the reply.
That is not the main principle of the invention, though is an aspect of it.
I suggest reading the english patent  translation that is available in the link I posted, it contains more information than just heat transfer.peace love light :)

It's NOT an invention. Patents mean nothing. It's a misinterpretation of a regular phenomenon.

I agree with that. Any electrical heater has an efficiency of 100%, including a bulb that is prevented from spreading light due to a housing.
The issue of electric heaters for a home is more about how the heat will be distributed (for example large surfaces at lower temperature give a better feeling than very hot point sources).

Hi all, thanks for the replies, even though they are not the most encouraging.

The cost has not been too great, so I figured I would test it out, either way, it will be a useful heater, we shall see how effective it is.

Just need to complete the wiring and cover the rest of the 100 watt bulbs.

".... 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.
peace love light
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.
peace love light :)

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.

Hi SkyWatcher123

Nice setup but inconclusive measurement.
May I suggest you immerse the light bulbs in a given quantity of distilled water in a plastic basin. Even if there is some current leakage in the water, it will not account for much due to the high resistivity of distilled water, but be careful about safety.
By measuring the temperature increase over time while stirring water to equalize the temperature, then you can calculate the minimum thermal energy that will be produced, thanks to the known heat capacity of water, and compare it to the electrical energy that will be consumed. A 5 minutes test should be enough.

J'accuse: by such a kind of measurement the experimentor will loose fairly 50% from the thermodynamic infraredemission effect which is based by radiation reflection.( more : Prof. Dr. Dipl- Ing. Claus Meier and Prof. Dr Dipl.-.Ing. Klaus Matschiner ).
In the U.S. and Canada there were several experiments whith comparison from light bulbs and heatpads which have shown 2/3 energy savings ( more with controler) for the heat pads.(lower surface temperature and greater radiation area )
It is also the kind of radiation( near or far infrared) which let us consumer feel well or freezing.The negative for the light bulbs, now envelopped will be that the 750 hours function validity will get shorten.The bulb and filament itself will heat up cause the transparency for the bulb external radiation is neutralized by the aluminium foil.

Measure inlet and outlet temperatures - Outlet - Inlet = Temperature difference.
If you have an Anemometer your can measure air speed at the outlet.  ( Amazon anemometer $13.00 )
Airspeed in mph x 5280 / 60 = feet per min.
Measure outlet dimensions and calculate sq ft.    Square ft outlet x feet per min = Total CFM.
CFM x 1.08 x Temp diff = BTU   3.41 BTU is the equivalent to 1 watt.
