Under the Palms

Thanks, you're making my day, it's a Gulf Coast, Bocca Grande, been flawless for 5 years. I'm going to refill it tomorrow after work.

Sent my son up and told him to drain the water and shut the breaker on our tub, he drained the water, but never hit the breaker, I went out to it about 10 hours later and it was running. The heat was turned down to 55, which was about the out side temp So what damage did I do?
