Is anyone familiar with Paloma instant water heaters. I found one with a frozen water coil. The OD temp was about 3 degrees. According to the Users Manual the freeze protection on the unit was only good to 4 degrees, Lower than that you are supposed to drain the unit. Thats a little rediculous if you ask me. Sorry its 2 degrees outside today, you can't take a shower. But anyways I wanted to check the electric heater, and the freeze protection t-stat on the unit, but I don't know where they are in the unit. There is a thin sheet of plastic in front of the coil that looks like it might be the electric heater, but im not possitive. Has anyone ran into this problem before? Thanks for any help.
