Frequently Asked Questions

What size chiller do I need for my cold plunge tub?

Chiller sizing depends on tub capacity and ambient temperature. For 100-gallon tubs, a 1/3 to 1/2 HP chiller is usually adequate for most climates. Larger tubs (120+ gallons) or hot climates may require 3/4 HP or larger. Consider that undersized chillers work harder and consume more energy long-term.

How long does it take to cool a cold plunge tub from ambient temperature?

Cooling time varies by chiller power, tub size, and starting temperature. Typical times: 1/3 HP chiller takes 6-8 hours, 1/2 HP takes 4-6 hours, 3/4 HP takes 2-4 hours. Initial cooling takes longest; maintenance cooling is much faster once target temperature is reached.

Can I add a chiller to an existing cold plunge tub?

Yes, most existing tubs can be retrofitted with chiller systems. You'll need to add circulation plumbing, electrical supply, and proper connections. DIY retrofit is possible for handy individuals, but professional installation ensures optimal performance and maintains warranties.

What's the difference between air-cooled and water-cooled chillers?

Air-cooled chillers are most common for residential use - they use fans to dissipate heat and require good ventilation. Water-cooled chillers use water to remove heat and are more efficient but require a water source and drain. For cold plunge applications, air-cooled is typically preferred for simplicity.

How much does it cost to run a cold plunge chiller?

Operating costs vary by chiller size, local electricity rates, usage patterns, and insulation quality. Expect $30-120 per month for typical residential systems. Well-insulated systems with efficient chillers and smart controls can minimize costs, while oversized or poorly maintained systems cost significantly more.
