Yes, cool and cold weather were made for hot tubbing! Cedar is a good natural insulator — and our tubs have many years of service everywhere from Alaska to Maine. It is crucial to have a good thermal cover, which is why we provide premium hot tub covers with an insulation rating (R-value) of up to 22. Our heater systems are thermostatically controlled and therefore automatically keep your water temperature above freezing. Our systems have freeze protection programming that will run the pump constantly if something goes wrong with your heater (e.g. you run out of propane). You will want to consider power outages if you are away from your tub for prolonged periods of time. The WiFi option is helpful in this situation as it will help you monitor at least for power/WiFi outages, or typically the temperature of your hot tub. If you expect to be away or don’t intend to use your tub during freezing temperatures the tub can be drained and shut off. Refer to your owner’s manual for details on how to drain and winterize your tub.
