How fast does your hot tub heat up?

Someone on this forum told me -Your spa, wired at 240v on the heater, should heat 8-10 degrees per hour. Ours heats up 2-3 degrees an hour. I figured nothing could be done, that it is what it is. The salesman told us it should take 8 hours. I later thought he said that because he didn't know or he just wanted the sale.

from 50 degrees or 80 degrees or 95 degrees? Colder water will heat slower and it should pick up a bit of speed as it gets hotter. 8-10 hours is not unusual depending on what temp you start at and how big the body of water is. Like @RDspaguyasked post pics of board and the schematic on the inside cover and we can tell you if it is wired correctly and the dip switches are in the proper position...this can make a difference in performance.
