In some regions, swimming pools can heat to uncomfortable temperatures during spring and summer months. Therefore, consumers often ask us at AquaCal about ways to cool their swimming pools. Here are some helpful tips.
You can cool your swimming pool by a few degrees by simply circulating your swimming pool water at night.
- If your swimming pool has any water features (fountains, waterfalls, etc.), you can also run them at night to accelerate the cooling process.
- You can install specialized misting bars on your swimming pool wall returns. Misting bars enhance evaporation and therefore help to cool your swimming pool. Keep in mind, however, that this method results in water loss from evaporation and thus requires you to regularly add water to your swimming pool.
- If your swimming pool has a solar heating system, you can run it at night to further lower your swimming pool temperature. As the swimming pool water passes through the solar panels, heat radiates to the cool night sky and lowers your swimming pool temperature.
Advantages of running your swimming pool pump at night include: simplicity and affordability. Disadvantages include: extended run times of your swimming pool pump, minimal decreases in swimming pool water temperature, and inability to control or maintain swimming pool water temperature, and required regular water additions due to evaporative water loss.
Mechanical evaporative coolers are installed in your swimming pool plumbing system after your pump and filter and before your salt chlorine generator. These coolers use fans to cool swimming pool water as it travels through the evaporative cooler system. By utilizing a cooler at night, you can lower your swimming pool water temperature by up to 10°F (6°C).
Advantages of mechanical evaporative coolers include: significant decreases in swimming pool water temperature and relatively low initial and operating costs. Disadvantages include: extended run times of your swimming pool pump, inability to control or maintain swimming pool water temperature, required regular water additions due to evaporative water loss, and susceptibility to corrosion when exposed to salt-water swimming pool chemicals.
Reverse-cycle heaters are also installed in your swimming pool plumbing system after your pump and filter and before any salt chlorine generators. These heat pumps use a refrigerant to maintain a specified swimming pool water temperature by running either heating or cooling cycles. Some reverse-cycle heat pumps can only switch on and off, while others, like AquaCal Icebreaker can also switch between heating and cooling cycles.
Advantages of reverse-cycle swimming pool heat pumps include: ability to heat and cool your pool on demand, affordability (especially when compared to gas heaters), and resistance to corrosion when exposed to salt-water swimming pool chemicals. Disadvantages include: high initial costs and higher operating costs than mechanical evaporative coolers.
So there are a few tips for cooling your swimming pool. By taking advantage of any of them, you can cool your swimming pool quickly and easily! If you have any thoughts, questions, or suggestions, feel free to leave us a comment below.
