Winter has returned to Colorado, along with some strong winds. Not securing the hot tub's lid down correctly, or removing it completely, can result in situations like this. In this case, a guest stayed at a property and did not understand the correct lid lifter operation. They left the lid off overnight and then left the next morning without covering it. This was the scene when we arrived to service the tub.
Typically, a hot tub will shut down if the water level gets too low, and it senses less water flowing through the heater. This is what will truly kill a hot tub by freezing and busting pipes, pumps, and heaters. Thankfully, this hot tub was brand new, and continued to try to run and heat without shutting off. That is really what saved this hot tub. Luckily, the owner also had an on-demand hot water system, and we were able to fill the tub with warm water. Of course we had to remove 90% of the ice first.
An open lid with cold weather and strong winds greatly speeds up the evaporation rate of the water in the hot tub. As the water levels gets lower the pumps will start spraying the water from the jets out of the hot tub itself. We recommend, and can install, wind straps to help save your tubs from situations like this. Again, they only work if they are used, and used correctly.
