Why Pool Water Evaporation is a Problem in New Zealand Summers
New Zealand summers can be hot and dry, causing pool water levels to drop quickly due to evaporation. This not only means constantly refilling your pool but also leads to higher water bills, wasted pool chemicals, and increased energy use if you have a heated pool. Luckily, there are effective ways to reduce evaporation and keep your pool topped up for longer.
Use a Pool Cover
One of the most effective ways to reduce evaporation is by using a pool cover. Pool covers can cut water loss by up to 95%, making them a must-have for any NZ pool owner.
- Bubble Covers (Solar Covers) – These are affordable and help trap heat while reducing evaporation. You can find them at local retailers like Para Rubber and The Warehouse.
- Automatic Pool Covers – These provide full coverage with the press of a button and are available from NZ suppliers such as Pool Covers NZ.
- Liquid Pool Covers – A liquid pool cover forms a thin, invisible barrier on the pool surface to reduce evaporation. These are available at Bunnings NZ and other local pool supply stores.
Install Windbreaks
Wind significantly increases evaporation by blowing water droplets into the air. Installing barriers such as fences, hedges, or glass panels around your pool can help reduce water loss.
- Consider planting evergreen hedges or installing a louvre fence to block strong summer winds. Check out PlaceMakers for fencing options.
- Glass pool fencing not only reduces wind but also enhances the look of your pool area. Companies like Euroglass have great options.
Maintain Proper Water Levels
Keeping your water level slightly lower than usual can help reduce surface area exposure to wind and sun. Avoid overfilling your pool, especially before a stretch of hot weather.
Reduce Water Temperature
Warmer water evaporates faster, so keeping your pool at a moderate temperature will help slow evaporation. If you use a pool heater, try:
- Lowering the temperature slightly instead of heating it to maximum levels.
- Running your pool heater during the evening or night rather than daytime to minimize the effects of the sun.
Limit Water Features
While water fountains and waterfalls look great, they also increase evaporation by exposing more water to air circulation. If possible, consider turning off these features during peak summer or using them sparingly.
Check for Leaks
Some water loss might not be evaporation at all! Undetected leaks can make it seem like your pool is evaporating faster than normal.
- A “bucket test” can help determine if you have a leak. Simply fill a bucket with pool water, place it on a pool step, and mark the water level. Check after 24 hours—if the pool level drops more than the bucket’s water level, you may have a leak.
- Contact a professional such as Leak Detection NZ if you’re unsure.
Best Times to Use Your Pool
Whenever possible, use your pool in the early morning or late afternoon rather than midday, when the sun is at its strongest. This simple habit can help minimize evaporation throughout the day.
Final Thoughts
By taking a few simple steps like using a pool cover, installing windbreaks, and maintaining optimal water levels, you can significantly reduce water evaporation in your NZ pool. Not only will this help lower your water bills, but it will also make pool maintenance easier throughout the summer months.
