Emerson 1f85-0422 Blue 4" Thermostat, Universal Staging/heat Pump, Programmable Review Dec 13, 2016

I have a hydronic heat system with 3 wire Automag controls and this is the first unit that I found to work with my system. Highly recommend!

Easy Installation Aug 10, 2016

I'm very pleased with how easy the installation was and the domestic hot water is fast and plentiful. I am amazed as to how quick the boiler heats and circulates the water through the system, I am curious to see how efficient it will be come winter.

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.
