It's very simple - when you keep resistive heating wire at constant temperature it has also stable resistance - depending on material. Then in resonant tank circuit and with some electronics you can keep the current circulated with a little input. Pure resonance. Of course it's all theoretic because I didn't made a working prototype. But I don't see why it would not work - the main problem with heaters or lights is their filament resistance is variable - if you find a way to make it static you can limit input current.
A solution to your problem I highlighted above is to use a zero or near zero temperature coefficient resistive wire for the heater. See this link as one solution:  https://en.wikipedia.org/wiki/Manganin 
Probably the resistive wire used in hair driers, bread toasters etc also has a low temp coefficient (I do not know for sure), you can check it by measuring the DC resistance just after the moments you unplugged them from the mains (after 1-2 minute run time).

 For an interesting patent application on induction heater for residential buildings, see German application DE202014001838 I mentioned it here a few minutes ago:  https://overunity.com/17861/bifilar-pancake-coil-overunity-experiment/msg526586/#msg526586

Exactly. I would prefer https://en.wikipedia.org/wiki/Constantan but in fact any resistive wire has some range of parameters where its resistance can be keep stable.

Hi all, Been working on designing and building a heater based on this french patent.
It will use 32 - 100 watt incandescent bulbs.
8 bulbs in parallel on each branch and 4 of these parallel branches in series, using 120 volts ac.
It will have an enclosure and a small fan for forced air convection.
Comments welcome.
peace love light

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.

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.

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.
