How to save energy with your hot tub?
-
Hot Tub Cover - If you cover the tub with an insulated top, it will use less energy to keep the set temperature.
-
Less Pumps - A hot tub with 1 pump will consume less energy but then you’ll compromise on the experience. Naturally, if you go for more enjoyment, you’ll have higher power consumption.
-
Size of the Tub - This is also proportionate with the size of the tub. A larger tub will require more power to heat and to move a larger body of water, and to operate more jets. This will be reflected on your electricity bill.
-
Usage - Using your hot tub 3-4 hours a week could mean an extra 100-120 Kilowatts on average.
-
Economical usage - This means your hot tub is used continually at least 3-4 times a week to ensure steady heating. If we let the system cool down, it will require more energy to heat it up again than keeping it on a constant temperature.
