Have you stuck your hand in your pool lately? We have, and let it be known….your water is still ice cold!
Water temperature doesn’t play a huge role in chemical balance, unless you’re dealing with hot tubs or winterized pools (water below 40 degrees), but people still ask about it.
So here are a few simple facts about swimming pool water temperature:
- If your swimming pool is screened in, your pool water will always be roughly 10 degrees cooler than open pools.
- A backyard with a southern is exposure is almost always best for pools. This will give your pool the maximum sunlight during the Summer.
- Water is the slowest element to change temperature. Even if it’s a very hot day out, there’s a good chance your water temperature is only creeping up a degree or two at a time.
- Heat pumps are all the rage – for now. Basically, pump and heater manufacturers have merged products, and the result is a pump system that heats water faster, and uses less energy. This could all change in the next few years with the growing demand for multi-speed pumps, but for now, they are a great option.
- If you decide to brave the cold water, and you start shivering, you may be entering hypothermia.
