Pools are a staple of living in the south. Yet just as with so many other things that people think they are familiar with, there’s a lot of misinformation out there. Here are a few common
pool myths paired with some facts from the U.S. Department of Energy that just might surprise you.
Myth: It takes more energy to heat up a pool than it does to leave it at a constant temperature.
Busted! If you will not be using your pool for several days, your heater will waste more energy keeping the water a constant temperature than it requires to reheat the water when you actually will use it.
Myth: It doesn’t cost much more to warm your pool an extra few degrees in warm climates like Charlotte.
Busted! It actually costs more – proportionately speaking – to heat your pool a few extra degrees in climates like ours. That’s due to the relatively low cost of keeping a pool at 78 degrees when your air temperature is warm. Every extra degree you heat the water adds 10% to 30% more in energy costs.
Myth: You need to run your pool pump continuously to keep your pool chemicals mixed.
Busted! As long as the water is circulating when you initially add the chemicals, they will remain mixed.
Myth: If I don’t keep my pool pump running, I’ll get algae in my pool.
Busted! Longer pump circulation times actually don’t impact the growth of algae. Scrubbing the pool walls and using chemicals are actually better methods of algae prevention.
Myth: Pool covers don’t make a difference when it comes to heating your pool.
Busted! Evaporation is actually the largest source of energy loss at 70%. Why? It takes 1 Btu (British thermal unit) to raise 1 pound of water 1 degree, but each pound of 80ºF water that evaporates from your pool takes a whopping 1,048 Btus of heat out of your pool, according to the DOE. By keeping your pool covered when it’s not in use, you can drastically cut evaporation loss (and the cost of replacing and reheating that water) by 30% to 50%.
