My sundance tub has standard and economy, I use economy most of the time in order to save on $$ on the electric bill.. There is a difference as far has how often the heater works..... it works for us
Thanks appreciate that. I noted in my manual that it will maintain temp to within 20 degrees of set temp. Being new to this, I was concerned that any saving in hydro by going to Econ mode would be offset by having to reheat water back to set temp. That being said, if temp drop is only 4-5 degrees per day, might not take much to bring it back. Do you know if it affects your circulation / filtration?
