We never heat our pool (even though it has a heater). You can use it May through September with no issues...sometimes more than that.

I remember as teens...we would sit in the hot tub in the dead of winter and then jump into the freezing pool to get the crazy tingles and then jump back in the hot tub.

I think my pool has a heater. It may be broken, but I've never tried to use it. Pool season is long enough down here as it. That said, it takes a while to get the water up to temp, so no real way to turn it on and have your pool hot in just a few hours. You really need to just leave it on al the time, just in case you jump in.

We are on our fourth pool with a heater.

Thoughts:
1. New heaters are vastly more efficient/effective than older heaters.
2. Heating pool water say 10/12 degrees is one thing heating water 30/40 degrees is another taking the best part of a day and costing $35/50 bucks.
3. Heating pool water in moderate to high winds is a huge mistake. Using a cover when heating in high winds is the only way to go.
4. 90% of the time we run the heater we simply heat the spa.

....and again, if you convert to salt-water pool ... water will heat faster thanks water molecules moving faster due to salt content. And think of the money you'll save not having to buy a bunch of chemicals. So with better / more efficient heaters and faster-heating water molecules...you'll come out ahead. Food for thought.

My kids have already been in the pool a few weeks ago. I wont go in until about mid-late April.

Is this a continuing April Fools joke?

Our swimming pool has a black finish , and I still heat it up even in the middle of Summer..... I like it at 95 degrees. And even on the very very hottest days in TX, it rarely gets above 92 degrees. Can't imagine why anyone would want to cool their pool.

We heat it all Winter long. In Winter, we heat it up to 98 degrees.....

Molecules moving faster? Nice personal theory there. It's really all about the heat capacity of chlorinated water vs salt water..... Salt water does have a lower heat capacity, but.... how much salt is in a salt water pool?

Well for what's worth and if I recall this correctly from my AP Physics class and from auditing class lectures in Meteorology/Oceanography: Salt water is a better conductor of energy like electricity than fresh water. This is because common salt is composed of Sodium Chloride which is an ionic compound and ionic compounds conduct energy / electricity very well as a solute. Soooo, in physics theory it should conduct heat quicker also, making its rate of temperature gain bigger and faster resulting in a more efficient & economic heating than a fresh water system. But hey, I bailed on being a scientist and got into finance instead, so what the heck do I know?

But my theory really isn't a personal one as you put it.... it is pretty common knowledge in my circle of peers.
