Thanks for all the reply. I will try and keep the tub at 102 for a few weeks and see if that helps with the power usage. $80 a month just seams really high to me for only using it a 2 days a week (if that).

Ok, thanks. I will try that. Just figured since it had been getting down to the 30-40's here it would work harder to maintain that high temp. I still think there is something going on with the spa though. I bumped it down to 84 Sunday night. I checked it this morning because I thought I heard it on.....and it was. It was running with the heat icon flashing and the water was at 91. I had it set to 84 so I would think it shouldn't be heating the water and the filter cycle wasn't set for that time either. What would cause it to come on when it isn't scheduled and it isn't trying to maintain at set temp?

Roughly how much should a spa cost to run (monthly)? My electric bill is between $70-80 more each month now since getting the spa. Everyone I talked to said it should be between $20-30. I have noticed the spa comes on more than twice a day. Is there something I can check or change to minimize that? It is a 2019 Caldera spa (2 pumps) and both filters are set to 30 mins each (daily). I'm in AZ so it doesn't get very cold. I set it to 102 on the weekends and back to 84 during the week.
