If you happen to own a hot tub, there are things you can do to make it more energy efficient.
Thermostat – First, take a look at where the thermostat is set. It should be around 102F. If you go on vacation, turn the thermostat down while you’re away from home.
Windbreaks – Create windbreaks around your hot tub. Privacy panels, landscaping or fencing are all effective at cutting wind exposure.
Blanket – Adding an energy efficient floating blanket serves two purposes. It helps to retain heat and reduces the amount of moisture build-up on the inside of your hard cover which will help it last longer.
Cover – Take a look at your cover. Is it hard (foam) with good insulation? Does it fill snugly against the top of the tub? A cover in good shape will decrease energy consumption from heat loss.
Energy Star - Finally, if you’re in the market for a new hot tub, look for an Energy Star model. An average-size energy efficient hot tub uses 5-7 KWh per day. A poorly insulated, inefficient hot tub can use 12-18 KWh per day; almost four times as much energy.
