We have a spa, which is a Campeche model by system pools (about 5 years old).
It seems to be heating fairly slowly at present - any ideas on what could cause that?
It seems to take around 5 hours to only movefrom 24oC to 30oC. The standby mode heats the water once a day or as necessary in the program functions. When you turn on one of the pumps, bubbles, light, or CD, it is supposed to be in On mode and the heater functions ad hoc but it doesn't seem to heat any quicker than standby mode.
Edit: Currently takes about 10 hours to heat it up from 22 to 38 whether in On / normal heating mode.
