If you use your Lay‑Z‑Spa regularly, say 3 or more times per week, it is usually better to leave your pump's heater activated at all times as this is the most cost‑effective way of running your hot tub and will save energy in the long run. We would recommend setting your hot tub at a temperature between 25°C and 35°C, and then increasing to your desired temperature a few hours before use.
Lay‑Z‑Spa's heating system is thermostatically regulated. Once the water reaches your desired temperature, it will stop and will only switch on again when the water temperature drops a couple of degrees. This is much better than letting your hot tub's water rise and fall from hot to cold, as this will require much more energy to bring the water back up to temperature.
If you don't use your Lay‑Z‑Spa regularly, you can either drop the temperature right down or off completely. Don't forget that all our hot tubs include the Power Saver Timer which lets you control your heating up to 72 hours in advance.
Regardless of leaving the heat on or not, we recommend that your filter is running for at least 8 hours a day.
