Hardware is about 84% of this estimate. The rest is electrical work, water care, and power.

Best fit if

You want cold water ready every day, one warranty, and no separate plumbing project.

Think twice if

Your budget is under $3,000 or you would rather choose and replace the chiller yourself.

Setup-specific electricity baseline: 35 to 110 kWh per month before climate, placement, target-temperature, and usage adjustments. Replace it with the exact model's rated input or measured energy use when available.

Estimate, not a quote. Real costs depend on the exact equipment, your electricity rate, installation, and climate. Read the chiller guide before comparing cooling equipment.

Assumptions and sources

These are editorial comparison ranges, not quotes or equipment specifications. Electricity uses setup-specific baselines of 35 to 110 kWh per month for a powered plunge, 55 to 160 for a tub plus chiller, 45 to 140 for a stock tank plus chiller, and 20 to 70 for a chest-freezer conversion before climate, placement, target-temperature, and use adjustments. The rate range is $0.14 to $0.22 per kWh, and water care uses $6 to $16 per month. Electricity is not derived from an HP label. Any HP class shown is only a starting point for comparing chillers you may buy separately. Confirm the exact model's rated input, measured energy use, and BTU/h at your tub volume, target water temperature, and ambient conditions.
