I have an 18k gal pool and spa. Last weekend my pool guy installed a new MasterTemp 250 and Sta-Rite 48sqft filter. I'm attempting to heater my pool for a party.
My goal is 84 deg which I set both the heater and Goldline control box to.
Beginning at 74deg, I turned on the heater at about 10PM last nite. 4 1/2 hours later the temp's at 76. Normal?
The heater kicks on for about 5 seconds at a time then kicks off for about 20 sec. On and off on and off. Is this normal? Shouldn't it just do this when maintaining temp?
How long should it take for my pool to get to 82-84 deg? At 2:AM the air temp was 60 deg if it matters.
Update: 6:AM temp hasn't budged past 76.
Thanks for any help.
