For those of you who code your own herms/rims systems what frequency do you switch the element at? I have my system at .95 Hz using the 16 bit pwm with a 16MHz crystal and prescale of 256. My concern is how the instantaneous power surge of a random turn on SSR could affect the system. Worst case scenario you could switch on at 340 volts (peak value of 240 RMS) so switching slower would extend the life of the hardware, but how slow is too slow? Switching too slow and you can have the case of fluctuating boil intensity.
