One of the quickest and most energy‑efficient ways to heat up an inflatable hot tub quickly is to use water from the hot tap. It is important that the water is no hotter than 40°C and that you add some cold into your hot tub first. Our recommendation is to fill your inflatable hot tub up to the bottom of the filter housing with cold water, then all the rest with water from the hot tap.
Every inflatable hot tub includes a lid and it is there for a reason – to prevent heat loss. Making sure that the lid is firmly in place when heating up your inflatable hot tub this will guarantee to have a positive effect on your heating‑up time.
Heating up during the hottest or warmest part of the day, especially in the summer, can help speed up the process. Temperatures always drop at night time so heating a inflatable hot tub during this period will be considerably slower and consume more energy.
The less exposure to wind chill, the less heat loss your inflatable hot tub will experience and the quicker it will heat up. A sheltered location can be as simple as in a corner space next to your house, alongside a tall wall, or if you can, in a purpose‑built shelter.
