Jacuzzi increased electricity usage

The charts I linked to have temperatures for 2014 and 2015, but unfortunately not for 2013 as the electric company did not provide that data. However, the much greater recent electricity usage occurs throughout the winter. The individual dates I chose for 2014 (Jan 18) and 2015 (Jan 1) show the temperature on those days. Jan 1, 2015 was 10 - 12 degrees warmer than Jan 18, 2014, yet electricity usage was significantly higher. On 1/18/14 the 4am 3-hour peak used 13kWh when the temperature was 22F. On 1/1/15 we used 21kWh with a temperature of 33 - 34F.
And 2014 used more electricity than 2013 - only 7kWh in the same 3 hour "peak" (although back then, the peak was all in one hour, which fits better with the fact the pump is supposed to run only for 30 minutes), although I do not have temperatures for comparison purposes.

I lowered the temperature to 80F and switched the filtration/heating mode to F0, which should mean that it operates for just 5 minutes, once a day. Sure enough, I now only had one peak, still at 3AM. However, it still lasted 3 hours and used about 16kWh. Ambient temperature was about 39F.
At least I have a lot of information to report to a service technician.

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.

My goal is to get electricity usage to back what it used to 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.
