Leaking HX on Vitodens 200
This HX from a Vitodens 200 was installed 7 or 8 years ago (by others) and poorly maintained. When we were called in to service it, it was loaded with debris and faulting the computer. The vent collar connection for the co-pipe was melted through the inner liner at the top of the boiler. After cleaning the appliance, we found the HX had a leak within the helical SS coil. The replacement HX took 7 days to get to Seattle, but that's another story. Never seen a leaking HX on a Vitodens before.
