Tankless Water Heater not Working - Need Help
Hi! So... Central California had a hard freeze the night before last. I left my cold water dripping to keep pipes from freezing and it seemed to work... woke up in the morning, turned on cold water ...

Looking at the diagram, it appears that he probably froze the water inside the water heater. Running a slow drip on hot may help, but you have to remember you have a lot of surface area in contact with very little water, so the cold will more easily freeze a tankless unit. I was hoping to see a "Winter" or "Frost" mode for an RV tankless like I have for my home tankless water heater. Unfortunately it looks like it doesn't. My vote is that he simply just froze up.
