How To Drain A Hot Tub For Winter. However, there is no insulation on the heater and as such it will lose its heat energy quickly and could freeze. You will now begin to drain your water.
The absolute best way to do this is to locate the circuit that controls the hot tub on the main circuit breaker board, and turn it off. Keep a good snow shovel close to the door that lead to your hot tub, so you can remove the snow around your hot tub and make a clear path to the spa. Generally, a warm insulated hot tub can keep its temperature for days before it would eventually freeze.
This ensures your hot tub is in working order before.
Also get a soft bristle broom to remove the snow and ice from the top of your cover. You will soon find the chlorine dissipates. First, before it gets too cold outside, completely change the water in your spa. You certainly don’t want your hot tub.
