Spas
Spas can be major energy users, so it's important to make sure you take steps to gain control over spa energy use.
The cost of operating a spa will vary, based on your habits. A study performed by one manufacturer shows that a spa in Florida can be operated for as little as $11 a month. Left unmonitored, however, spa cost can be three to four times higher.
That's why FPL offers these easy and effective tips to help you enjoy your spa while keeping energy costs down.
Spas use energy in two ways:
Spa heating
Heating is usually the largest part of spa energy cost. But there are simple steps you can take to keep the cost of spa heating down. When deciding how warm to keep your spa, remember that the warmer the spa, the higher the cost of heating. Select a safe and comfortable temperature based on who is using the spa:
- The National Spa and Pool Institute considers 104° F to be the maximum safe water temperature for adults, for up to 15 minutes.
- Children are more sensitive to heat, so limit water temperatures to 95° F and spa time to 10 minutes or less.
- Pregnant women and persons with heart disease, diabetes, high or low blood pressure should discuss spa use with their doctor first.
Tips
Step
| Action
|
| 1 |
Heat your spa only when you plan to use it. |
| 2 |
Keep your spa heater's thermostat at the coolest comfortable temperature, and no higher than 104°. A spa thermometer will help you find the temperature that is perfect for you. |
| 3 |
Use a spa cover to put a lid on heating costs. Covering your spa when it's not in use can cut heating costs in half. If your spa doesn't have a cover, use a floating spa blanket. |
Spa pumps
Spas use one or more pumps to
- provide bubble jets and
- filter and circulate water.
Control pump energy use by following these tips.
Step
| Action
|
| 1 |
Bubble jets inject cool air into your spa's water, causing heaters to work harder, so turn off bubble jets when your spa is not in use. |
| 2 |
Recommended pump run times vary based on the type of pump used. Some spas use an efficient low-speed continuous circulation pump, while others use larger pumps for a short time daily. Run filter pumps according to installer's minimum recommended daily time. |
Shopping tips
- Look for spas that are well insulated. A spa with full foam wall insulation and a tight-fitting insulated cover will cost less to heat.
- Spas equipped with low-speed continuous circulation systems can save energy.
