Uncovered Outdoor Spa Word on the street is that, supposedly, maintaining a constant spa temperature saves more energy than lowering the temperature or turning the heater off. Word on the street is wrong, at least on that street (it's still hip to wear pants). Heating a spa can consume a whole lot of energy—spa and pool heaters top the list of the 25 most energy-consuming home appliances. Raising spa temperature one degree can tack on 10 to 30 percent more in energy costs, depending on your location (so says the Department of Energy). The average spa temperature range is between 90 and 105 degrees, so you can save money by keeping your spa temperature set to 90. You can also turn the spa heater off when you aren't using it.
