I was given a Hot Spring Classic Model F (Ser #: F-401049) and it has some heater issues. The previous owner said he had to reset the heater every 30 minutes. It looks like one or more parts have been retrofitted or replaced, but I can't tell. I was thinking of upgrading to a 220V system since I already have the 220V electrical box on the outside of the house. I have no idea what year the tub was manufactured and want to make sure upgrading to a 220V spa pack is the way to go. If it is, what brand or model spa pack should I look at? Any help would be greatly appreciated.
