Due to the unfortunate increase in electricity bills, I have chosen to half-wave rectify our boiler heater to a degree, where our meter won't even notice "free-energy" is being consumed.

The former being put to one side, the latter will be, what are the mitigation factors that will compensate significant harmonic effects that can damage internal domestic electrical equipment?

 

I don't understand how half-wave rectification will give you free energy. Your meter will still respond to the real power consumption.

I was hoping that, if I transposed the boilers load into third harmonics or possibly even higher, the boiler could go unoticed by the meter, and the after effects could be attenuated through the lighting circuits.

Now due to an obvious reason, I have not thought this through properly.
