Darn it’s taking a long time to heat up my jacuzzi on the 115v  line, the electrician ordered the 40 amp gfi breaker to change it over to 220 v line but it hasn’t come in yet.  At this rate it won’t be heated up until tomorrow evening as it’s only going up 1 degree per hour.  Water temp was 56 degrees when I plugged it in at 4:30 yesterday afternoon and at 7 am this morning its only at 70 degrees.  I’m not going to like my electric bill this month!  Who ever buys a plug and play that doesn’t convert to 220v are crazy!  So all in all it took 68 hrs to heat to 104 degrees.  Forgot to mention and I live in Arizona…….well sadly after it finally heated up something internally went wrong and it kept throwing the gfi off.  I waited 10 months as the 1st one got damaged in transit, now this happens.  But they are very good at communications and I got a refund on my spa.
