If you are not planning on using your spa for at least two weeks, it’s a good idea to lower the temperature to the lowest setting (80F or 26°C) or set to low range heat mode in order to reduce your operation costs. Keep in mind, however, that you will need to adjust the temperature settings 4 hours before in order to return the water temperature to 100 F (38°C).
It’s also important for all non-use periods to visually check that the spa is functioning correctly and to maintain the water chemistry. This will prevent corrosion, staining and/or scaling. If you are not able to check and maintain your spa on a weekly basis, you may want to consider winterizing your spa.
