Estimated monthly electricity cost
$19/mo
About 120 kWh/month under the selected assumptions.
A monthly-mean calculator cannot reproduce weather variability. City pages use monthly low/high climate profiles and are better for annual comparisons.
The formula
ArcticSoak estimates daily energy as baseline circulation plus an explicit usage/exposure allowance plus conductive cooling load divided by chiller efficiency:
daily kWh = baseline + allowance + [UA × max(ambient − target, 0) × 24 ÷ 3,412 ÷ COP]
UA is effective thermal conductance in BTU/hour/°F. COP is the coefficient of performance. The scenarios are sensitivity tests, not manufacturer ratings or statistical confidence bounds.
Worked example: At 80°F ambient, 50°F water and $0.16/kWh, the reference inputs (UA 18, baseline 1.6 kWh/day, allowance 0.55 kWh/day and heat-adjusted COP) model about 120 kWh and $19 for a 30.4-day month.
