I just bought a house that has a Hayward pool heater. I have never owned a pool with a heater so I have some basic questions I am hoping someone can answer for me:
1- The pool heater is Hayward but I am unsure of the specific model. Does anyone know where I can find a model number or tag? I do not see one externally so is it inside?
2- My pool is at about 70 degrees and initially I set the pool heater to 85 and let it run for a few hours. When I reached into the pool and felt the return lines the water felt warmer, but not as hot as I would expect. Is this normal?
3- How often does the heater need to be run/should be run?
4- How expensive (natural gas) is to heat the pool now to around 84 when it still is getting into the 50s sometimes at night (Atlanta, GA)?
5- The down temperature arrow on my heater does not respond. I tried pressing the up arrow hoping it would hit 104 which is the max temp and then cycle back down, but it did not and is now stuck at 104. Is it safe to run the heater set to 104? I only want the water in the low 80s so I figured I could just turn the heater off when that temperature is reached, correct?
6- I also saw another forum where someone had a similar issue with the arrow not working and it was suggested to get a replacement keypad (FDXLBKP1930). Does anyone have experience with this and is it what I need to do? Is it hard to install?
Thanks for any info!
