About 3 days ago, I woke up freezing cold in the morning and looked at my thermostat and saw that it was way below where it usually is in the morning, usually around 50 degrees as it turns on automatically. I turned the thermostat on and up to 65. Later that day as I was in my room all of the sudden a pipe burst. A family friend and certified plumber came over and fixed the pipe but still no heat. There has been years where all winter this room was not used and the heat wasn't turned on, so I find it hard to believe that the water in the heaters are broken. Does anyone have any ideas on what the potential problem could be?
