How to spend less running a hot tub
- Cut the hours: A hot tub at 4 h/day runs about $30.60/month — trimming one hour saves roughly $7.65/month.
- Lower the setting: running a hot tub on a lower or eco setting drops the wattage directly.
- Upgrade efficiency: a newer hot tub near 1,000 W uses far less than an old 6,000 W one.
- Kill standby: a smart plug or timer removes the ~100 W it draws even when off.
