Glacier Pool Coolers

Start with pool volume. The GPC-25 covers pools up to 20,000 gallons, the GPC-210 up to 30,000, and the GPC-215 up to 45,000. But your run schedule matters just as much as pool size. If you plan to run the cooler all day, the GPC-25 handles up to 15,000 gallons comfortably. If you want to run only at night, say midnight to 6 AM, you need more BTU capacity: a 15,000-gallon pool in a 6-hour window needs the GPC-210 to get a meaningful drop (roughly 7 degrees vs. 3.5 degrees with the GPC-25 in the same window). Not sure? Call us at 800-809-3741 and we will size it in five minutes.

Yes. Evaporative cooling works by evaporating water into passing air, and high humidity slows that process somewhat. In dry climates like Las Vegas, where overnight wet bulb temperatures fall below 65°F in summer, a Glacier cooler meaningfully exceeds its rated output. In humid cities like Miami or Myrtle Beach, where overnight wet bulb stays around 76 to 78°F, you will get performance close to the spec-sheet numbers. The units were developed in Houston, so they are designed to work in high-humidity conditions.

Yes. All three models plug into a standard 115V outlet. Any Wi-Fi smart plug (Kasa, Amazon Smart Plug, Wemo, and similar) or mechanical outlet timer will let you schedule the cooler to run during specific hours, turn it on or off from your phone, or integrate it with Alexa, Google Home, Apple HomeKit, and SmartThings. Glacier does not sell a proprietary app, but because the unit is a simple plug-in load, any outlet-level smart home device works with it.

All three models require a dedicated 20-amp, 115V single-phase circuit. The GPC-25 draws only 2.66 amps at run load, making it very inexpensive to operate. The GPC-210 draws 8.5 amps and the GPC-215 draws 12.5 amps. All three are within the safe capacity of a standard 20-amp residential circuit. If you do not have an outdoor 115V outlet near your pool equipment pad, a licensed electrician can add one for roughly $150 to $300 depending on distance from the panel.

In most cases, yes. The cooler connects to your return line so warm pool water passes through the unit before returning to the pool. The GPC-25 uses 1.5-inch fittings; the GPC-210 and GPC-215 use 2-inch fittings. Compatible with both above-ground and inground pools. The unit requires adequate pump head: 5 feet for the GPC-25 and GPC-210, and 5.3 feet for the GPC-215. Most standard pool pumps handle this easily. If you are unsure, contact us before ordering.

Both models flow water at 30 gpm, which is why they are often confused. The difference is air volume: the GPC-210 moves 3,531 cfm versus 2,118 cfm for the GPC-25, a 67% increase, which doubles the BTU output (150,000 vs. 75,000 BTU/hr). More air through the same water volume means more evaporation and more heat removed per hour. For a 15,000-gallon pool in a 6-hour overnight window, the GPC-210 delivers roughly twice the temperature drop of the GPC-25. The deciding factor is almost always how many hours per day you plan to run the cooler.

Evaporation loss is 0.93% of the water flow rate across all three models. At 30 gpm, that is roughly 17 gallons per hour. Over an 8-hour overnight run, expect to add about 135 gallons to the pool. The GPC-215 at 45 gpm loses about 25 gallons per hour, or roughly 200 gallons over 8 hours. All three models include a 0.5-inch auto-fill inlet so you can connect a float valve to maintain pool level automatically.
