System Reliability Jul 24, 2016

Two days after installation, the 12k unit quit working with a fan malfunction code. Efforts to contact Gree have been unsuccessful. The 9k unit continues to operate normally. Warranty/repair is a real issue.

I replaced a Dunkirk XEB-3 (20 yrs. old) with the Dunkirk boiler above. The new one is all most identical to the old one, that is the pipes were located same as the old, so gas and water lines were easily plumbed. The old electrical wires could be used although lengthened to connect to the digital controls. The circulators location has changed, it's still provided with its wiring provided. Venting is the same as the old one. I was happy to get another Dunkirk that installed easily.
