So today I was doing my usual dog poo detail and thought I noticed the sound of the spa heater going. I was next to the spa but the heater is on the other side of the yard so I dipped my toe into the spa to make sure I hadn't left it on the night before. It was fairly cold so I didn't think anything of it and figured the noise I heard was just the filter pump running. I finished picking up the poo and the decided to check my pH and chlorine. I sat down next to the pool and reached in to fill my tester bottle and the pool was HOT! Not warm, but very hot. I checked the temp and the pool was 100 degrees. I now have the heater set to auto shut off after 1 hour. I had it set up like this before and had changed it since we are running it with the remote now, but last night I ran it all manually so it didn't shut off. It was an expensive lesson, but at least we got to swim and enjoy it for the first time since we built the pool. It had been running about 17 hours and raised 30 degrees. Hopefully with the solar cover we can keep the heat in long enough to swim a few more days.
So what kinds of oops stories do you guys have?
