One of the most common questions prospective outdoor hot tub owners ask is about electricity consumption. The good news is that with the right setup and a few simple habits, you can significantly lower your energy bills without sacrificing your home spa experience.
Here are 6 proven ways to make your MSpa hot tub as energy-efficient as possible:
1. Use an Insulating Ground Mat Under the Hot Tub
The greatest heat loss in portable hot tubs comes from direct contact with cold surfaces such as tiles, concrete, or decking. Placing a dedicated EVA foam thermal insulation mat underneath the base creates an effective barrier against the cold ground. This slows down heat loss considerably, meaning the heater runs much less frequently.
2. Always Put on the Thermal Cover When Not in Use
Heat rises, which means an uncovered water surface loses warmth rapidly, especially in the evening or on breezy days. Always cover your hot tub with the original buckled cover as soon as you step out. For even better insulation, place an inflatable thermal bladder underneath the main cover—it sits snugly over the water, prevents evaporation, and traps heat inside.
3. Choose a Sheltered and Sunny Location
When deciding where to place your hot tub in the garden or on the patio, look for a spot sheltered from the wind, such as next to a house wall, fence, or hedge. Wind cools the outer walls of the spa very quickly. If the spot also gets plenty of sunlight during the day, the sun's rays will help maintain the water temperature completely free of charge.
4. Use the Air Bubble Function (BUBBLE) Wisely
Massage bubbles are one of the most popular features, but they draw cooler outside air into the water, which gradually lowers its temperature. Run the bubble function only while you are inside enjoying the massage, rather than using it to circulate the water when the hot tub is empty.
5. Maintain a Steady Temperature Instead of Turning It Off Completely
Many owners switch off the heater completely after each session, but reheating hundreds of liters of cold water from scratch consumes far more electricity. If you use your hot tub regularly (for example, 2–3 times a week), it is much more economical to let the heater maintain a moderate constant temperature (around 33–35°C) and raise it to 38°C an hour or two before getting in. Use the built-in delayed start timer on your MSpa control panel to schedule heating right for when you return home from work.
6. Clean the Filter Cartridge Regularly
A clogged filter restricts water circulation. When water flow is weak, the pump and heater have to work longer and harder to reach your target temperature. Rinse the filter cartridge once a week and replace it on schedule—this saves both electricity and water treatment chemicals.
