If you are wondering what is the best temperature for a hot tub in the winter so they won’t freeze when they are not in use, you’re probably also wondering if you may be able to save some money on energy costs or if adjusting the settings can extend the life of your spa.
It’s pretty simple really. It is best to keep your hot tub at the same temperature all the time, that is, if you’re going to use it regularly. By regularly we’re talking at least several times per month.
Unlike some other brands, Royal Spa hot tubs are extremely energy efficient and retain heat very well. This means they don’t cost much to run in the first place, and you can feel comfortable setting your spa at your normal soaking temperature and leaving it.
Most people prefer temperatures between 102-104°F. If you’re a 102°F (39°C) kind of person, set it to 102°F. If you like 104°F (40°C), set it to 104°F. And if your name is Goldilocks, well you might prefer 103°F (39.5°C).
