You CAN save money by lowering your spa's temperature IF you keep it low enough long enough vs the time the heater runs to bring the spa temperature back up.The trick is figuring out if it saves you any money based on your specific usage pattern.The more often you have to bump up the temperature, the less you'll save.It a matter of how much time the heater runs during a given period.The less often (in accumulated minutes/hours) the heater comes on the less you'll spend on power. For my particular use pattern, it wouldn't save enough to bother with.YMWV.
why haven't any spa manufacturers equipped their spas with programmable thermostats.
I have one that controls my HVAC system for my home. It's one of those 5 star energy savers. I have it set to a temp 4 degrees cooler when I'm at work and also set to a temp 3 degrees cooler when I'm sleeping. I've had this PT for a couple years now and I've definetly seen a significant drop in my heating and cooling bills. So my question is this, I have always been under the impression since I've joined this site that one should just set their spa's temp and forget it. Because maintaining a tub at 102 versus turning it down 3 or 4 degrees and then turning it back up right before usage would be a wash. Although I haven't seen any documentation on this it seems to be the consensus here. So, I obviously beleive them as some of your guys knowledge with spas is just remarkable, but seriously though why do we save money in a home but not in a spa with a programmable thermostat. :-/Thanks,Chad
Never mind turning it down, turn it up when you're home!My house is at at least 71º when we are home and 65º when we sleep. I have it turn down to 60º whe we go to work.Heck, Icicles must come out of your shower!!! To keep it tub related - does your tub have an economy mode?
I'm afraid to go any lower than 62.
