Unit arrived as stated and well packaged. Instructions were easy to follow and correct. Did the installation myself with only some help to mount unit. Well pleased with results.

Emergency Replacement Jul 27, 2016

Away from home for the winter. Family checking our home found the problem, needed a new boiler. I was in another state, went online (this boiler was recommended by the professional), able to work well on your web site. Called a few times with questions, very helpful. Shipped out immediately. Boiler installed without any problems. I returned home a few weeks later to a warm home new boiler, and every thing working well.

My suggestion is to have a very experienced high efficiency furnace plumber install the unit. From what I now know all aspects of the system need to be in balance to work properly. My unit is exceptional and my wife likes the colored pictures designating the various modes of operation.

Great Product! Dec 15, 2016

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.
