Hot Tub Cost by State

A 4-person 240V hot tub kept hot year-round with a well-insulated cover. Heater cycles on/off; effective draw averages ~25% of peak (higher in winter, lower in summer). Poorly-insulated tubs or those left uncovered can use 2-3x more electricity — a good thermal cover typically pays for itself in one winter of running. Running one costs about $619/year at the U.S. average residential rate (18.83¢/kWh) — but the range across states is significant: from $406/year in North Dakota (12.35¢/kWh) to $1531/year in Hawaii (46.62¢/kWh).
