Cool the Hot Tub in a hot summer! We just bought our 6th hot tub and were very happy with it until the Arizona summer oven hit. The temps are regularly above 110 degrees. This summer is setting records. If we leave the insulated cover on the tub it will easily see water temps of 105. Way too warm to sit in, especially if the morning temp is already at 90. We left for a weekend vacation to California and came back to an error code of ” OH ” (which we found out it meant the spa was over heating) What to do??? We tried putting in frozen milk jugs of water, but that only cooled down the water temp a couple of degrees. A chiller was recommended but that would be out of our price range. We also tried putting the tub in economy mode but that didn't work either. I did notice that that swimming pools in our area are not covered and they never get that hot. So why wouldn't that work for our spa in the summer time. But we didn't want to have leaves and debris get into the tub. We wanted to have something that would allow cooling but still keep debris out, so we bought a fiberglass screen that is meant to cover screen doors (Amazon). In the evening we would pull open half of the insulating cover and put the screen over the uncovered part of the spa. We usually sit in our spa in the mornings) Like I said on some evenings it only cools down to 90. But by leaving it half open overnight, the water temp would cool down to a more tolerable 95 to 98 for our morning soak. So with the idea that more is better, we bought some PVC and a fiberglass screen that would cover the whole tub. We put together the PVC to create a frame and laced in the screen and now have that to cover the tub. With the tub open all day long the water temp reads a high of 93. It may go lower than that but we have the heater set at 93. Success, so far!!! Will let you know if we are getting too much dust and other fine particles in the water. A frequent cleaning of the filter will tell us something, I hope. Let's see how this works out. sreno
