How to Keep Heat in a Hot Tub with the LX H30-R2 Ambient temperature and the state of your tub’s equipment contribute to how quick water heats up or how fast it loses it. The same goes not only for hot tubs but in whirlpool baths and spa systems.Where your hot tub is installed and how tepid the water is contributes to its ambient temperature. The higher the temperature of the water and of the environment will mean the water heater will not need to take a longer time to heat water to a comfortable temperature.A comfortable hot tub temperature runs from 38℃ or 100℉ and 102℃ or 102℉. It is recommended that water temperature must not exceed 40℃ or 104℉. As a water heater will take hours heating your hot tub, ensuring equipment such as jets, water pump and the LX H30-R2 flow type water heater are operating in tiptop condition. Placing a cover on the hot tub is a good way to keep heat from escaping when it is not in use.When your hot tub is not keeping heat in, you can check the filter and spa circulation for debris and clean it. The thermostat, heat sensors, and hot tub control panel must function properly.
