    Re: Chlorine neutralizer??

    The room was at 61 degrees before I turned the pool heater on. The difference between 61 and 68 is huge though. Humidity didn't really seem to change in the room.

    I was shooting for water temp of 80 degrees so I'm right where I wanted to be, but I need to get the wife in there tonight or soon because she's the one who gets cold the easiest.

    Re: Chlorine neutralizer??

    Well we all went in pool tonight, the wife said it was cold until she got in, then said it was fine. Humidity definitely went up during the half hour we were in which warmed air temp by 2 degrees. 42 degrees currently outside so I will have to see if outside temps affect the room much. We did notice for sure that leaving an inside door open created draft immediately coming back in through the exhaust vent for pool room. Makes sense because normally air pressure would be equalized therefore not drawing from outside until a door was opened but I will talk to HVAC guy about that also.

    80, eh?! I'm personally good down to about 86. I prefer 89-90. Below 88, my guests complain or don't stay in for long. My exhaust vent has a damper, but I keep the vent going the entire time the cover is off anyway, so no doubt that drafts play a role.

    Did you cross-check your thermometer with another? I'm surprised that your wife was ok with water that cool.

    I re-calculated the size of my pool and I think it's about 18,500 gallons so I don't think mine is way bigger than yours and we have the same BTU heater so I'm curious since we have the same sort of setup, how many hours a day do you need your heater running to maintain 90? I have a calibrated thermometer here at work I'm going to take home and cross-check with the one in the pool.

    Re: Chlorine neutralizer??

    I wish I could tell you, but I have too many moving targets. It depends on if I use it or leave it covered, ambient temps, how long the pool has been warm, RPM on my pump and the health of my heater.

    A year ago I had a single-speed 1.5 hp 3450 RPM pump. The water would heat about 1 per hour. The heater and the pump shared a timer. I ran the pump twice per day for 2 hours plus during any swim time. The temp was maintained with routine, but I don't know how much of that time the heater was firing.

    In February I installed a VS pump. I also learned with the help of TFP guidance that my pool needs much less circulation that I originally thought to stay clean. I slowed pump speeds and reduced runtime. The other issue is that the VS has it's own timer, so now my heater can kick on independently of the pump. The heater appears to be dying, but I don't want to kill it!

    Even with COLD water at high speed, my heater t-stat cycles on and off. The colder the water the less time it's off, but I was disappointed this week to watch it cycle while ingesting water at 63. I seem to be getting around one half degree /hour now. Pump speed doesn't seem to play a large role in this situation, but I'm still experimenting with that and hope to replace the circa '92 heater with a slightly larger one this winter. (I'd like to go as large as my flu can accommodate)

    I use an infrared gun to monitor temp. I have two, and they disagree by 2, so I go with the one that agrees with the rubber ducky floater. That's to say I could be 2 or more degrees off.

    Re: Chlorine neutralizer??

    Been keeping it at 85 which seems just about right. Finally got the thermostat labeled for the temperature (it's just a analog dial thermostat). I also run my pump twice a day for 2 hours each haha. Not during swimming though. I'm not sure what you mean by the heater coming on independently of the pump, how would the heater come on if the pump wasn't on?

    My heater also pushes the temp by about 1 degree per hour. We put a 6" liner in my chimney flue for this heater even though Hayward calls for a 7". No problems so far and it was my HVAC guy that said he was ok with it.

    Re: Chlorine neutralizer??

    If you're good with 85, I may have to give 86 another shot! Are you really active in the pool? My favorite pool activity is almost no activity. lol that might have something to do with it.

    My pump and heater are below the bottom of the pool. The pressure switch on heaters can adjusted for that, but mine doesn't work - it allows the unit to fire without flow. I'm shopping for heaters now, and I'm looking forward to having that protection.

    Re: Chlorine neutralizer??

    Gotcha, yeah mine fired one time with no flow and I thought the pipes were going to blow up it was so loud. It turns the residual water immediately into steam and starts a loud banging noise and makes the pipes super hot. Thank goodness I was in the basement to turn it off when it happened or I might have a swimming pool for a basement. Needless to say, I replaced the pressure switch at the same time as I put a new heat exchanger in it and no problems since. I have a 5 year old so I'm a bit active in the pool playing with her, when she's not there I'm not that active but usually adult beverages are involved which eases any coldness haha.

    wow! In your shoes, I think my "flight" instinct might've overtaken "fight"! Potential steam burn. ouch.

    I don't have kids, but I've posted a pic in the gallery of a margarita floating on a kickboard...

    Longshot, is your skimmer the old style that the main drain ties into with a 'spaceship' disc in there? I doubt this since you have a 3 way valve by your pump but look anyway

    I'm not sure what I should look for, where would this spaceship disc be?
