Review:
"Ownet"
We had our Dunkirk installed when we built our new building. Last year in the middle of January, the heat exchanger started leaking in the back. I called the installer and he said he would do what ever it would take to get it repaired or replaced. Dunkirk was called with this reply, "have the installer pull it out, send it to the distributor and they will send it to Dunkirk for review." They, in their sole judgement will check to see if the pH was correct in the fluid and make a determination if it was a manufacturers defect. If it was, they would replace the unit, send it to the distributor, then to the installer who would put it back in. If it was not defective it was $1700 for the exchanger. Guess what happened. None of the above because going three weeks with out heat would have frozen my bottom. I replaced the boiler with another brand that actually has customer service. Dunkirk is a brand I would avoid at all cost. So much for a ten year warranty. Zero is more like it.

Review:
"DO NOT BUY DUNKIRK"
This unit is not energy or cost efficient. It short cycles constantly because of wind affecting the concentric vent in the Rocky Mountains. The unit has gone through 3 ignitors, two induced draft blowers, which are noisy and vibrate like they are not rotationally balanced, and an air pressure switch. The customer service is awful at Dunkirk and they spend more time defending the product and blaming you for misusing it than trying to solve the problem...and they do not listen to you but rather tell or lecture you on your misdeeds. I was told the air pressure switch has a paper element inside and is subject to condensate or water damaging it and I must have installed the concentric vent improperly. This is pure bs..I disassembled the failed air pressure switch and the diaphragm is made of SILICON RUBBER. I tried to get replacement parts and Dunkirk referred me to their list of dealers and distributors and not a one of the companies I called had ANY parts and they all said they discontinued a relationship with Dunkirk. The rep in Denver gave me the same party line story about the air pressure switch having a paper diaphragm etc etc.....he has obviously never seen the inside of one...he also did not have any parts. Dunkirk refused to sell me the parts and I had to go through one of the authorized 'dealers' who would then only sell it to an hvac contractor. Two hvac contractors came to see the unit and spent most of their time bad mouthing Dunkirk and recommended that I scrap the unit and buy a competing brand. Both refused to work on the unit afterwards. I will not buy another Dunkirk.
