Hi Elephant!
All my excuses!
I forgot to mention that it is for the new electronic counter and that for the old ones it still works, as it will replace them all if it is not already done, I have not mentioned it!
Mine is a new type and my consumption has increased by 20% since the replacement !!!
Besides, a manufacturer had released an electronic thermostat which clipped the pulse which allowed to distort the old meters but Hydro-Quebec quickly realized it!
Reduce the power of a heating resistor of 3KW-220v
Resistance picture

just unplug 1 or 2.
Dirk pitt out of curiosity I opened the box and:
Exterior view:
Interior view:
Well two wires for the resistance and two wires for the probe

An example of a stp diode

Another solution is a diode in series to reduce the power by half.
Be careful, you need strong: 400 V, 15 amps. and a suitable radiator.
Hello Elephant
Would this type of diode be OK?

On the other hand to fix a radiator above
And if I understood your reasoning correctly, I put it in series with the phase or the neutral of the resistance?

Well, apparently, no radiator, I was thinking of another type, designed to be mounted on a radiator, but it will be fine.
you go up in series, as if it were a switch.
No need to worry about the polarity: we are in AC: we "cut" half a sinusoid out of two.

Does that divide the power by two?

Do you have any idea about the remaining power?

theoretically half: 1500W
By cons not sure that a small diode of this kind will last a long time. it's still not far from 15W to dissipate, it will heat well in any case!

How is this branch?

Thank you Forhorse
By cons to put it in series I weld as below?
PS: Sorry but I am not fortunate in electronics

With the diode, you will inject direct current into the network ...
In addition the peak current will not change: it will always be 18A, I do not know if the circuit breaker will let through if other devices are connected at the same time ...
The best solution would still be to have a lower power resistance ...
Note that for the diode of which you give the picture, one of the wires is fixed with a terminal with holes on the part "bolt" of the diode; the heat sink is therefore at the potential of the sector, beware of your fingers!

+1 I have one of 3000W that I only wired in 1500W ... after I do not know if in the long term it is really interesting for energy savings?
If not possible, as said above make a voltage divider bridge or lower the voltage with an electromagnetic rheostat (I have no confidence in the electronic assembly presented above)
