Welcome to our forum.
Hard to say what would cause the increase. Cover for sure but after that to many variables. As far as the filter cycle on F1 yes it should run pump 1 on low for 30 min twice a day if I remember right. If it calls for heat the heater comes on. You might try shutting the power off for 20 min reset the filter cycle and see if it changes anything. Are you saying that pump 1 runs for 3 or 4 hours on low in the F1 setting?
One thing you omit to mention is how the ambient air temps differ from one year to the next.
Not sure what your goal is? A spa does what it does. Pumps draw so many amps and so does the heater. Being your spa is 8 years old and out of warranty. About the only thing I can see doing is changing the circuit board which will be in the 4 or 500 dollar range, an updated eprom chip may change it. If that doesn't fix it then it's hit and miss with replacing pumps and heater which again is parts and labor with the end result being the same most likely. Not sure why it's spiking your electric use but also not sure what else it can be.

I had hoped my problem might be a known situation and someone would be able to say "Ah, yes, that sounds like.....". I will call a tech out. Even if it costs $500, I will get that back in a little over a year if usage can be reduced to what it was previously.

If you do find out what the problem is, please post back on this forum and let us know. I also have a Jacuzzi J-345, although mine is only one year old. Would still like to know what the issue is though. Thanks.
Where did you get the cover and what specs does it have?
