"Oh Boy What a mistake"
We installed a 90% efficient boiler in 2005. We have had nothing but trouble since. The furnace has not worked one full year yet without problems. Right off the bat the pressure swithes needed to be reofitted by the manufacturer and placed higher in the boiler case. Replaced three igniters, two pressure switches. The boiler water sensor keeps clogging causing the boiler to shut down. We have had repeated survice calls, the company that installed our boiler strung us along and now refuses to replace this lemon. Furnace unit is incredibly noisy when it works...Never buy a Dunkirk Boiler, Very unhappy!

We installed about 40 Dunkirk Aluminum hex boilers with about 30 hex failures. You get a new heater exchanger, have to send the failed on back on your nickel, a day of labor to install new heat exchanger with no labor reimbursement. What a nightmare and expensive! Buy stainless steel. Oh by the way, aluminum oxide plugs up air vents, flow meters, piping, pumps. Amazing they have been in business for 75 years and make a horrible excuse for a boiler.

"Reliable when properly maintained AND installed."
All of the problems I have had with my Dunkirk oil fired burner were due to installation issues, mainly poor solder joints, poor compression fittings to oil tank, etc. Then, add clueless technicians over the years and inevitably their incompetence will cause issues later on. So, the boiler is fine. Make damn sure you get a quality install and find competent technicians who will fix the problems they find! 14 years old, reliable as hell if the annual tune up is done properly. One board and one sticky 79 cent electromagnetic switch. Use a boiler mate. Hot water forever and no leaks!

"You get what you pay for"
Our Dunkirk 3ew is less than 10 years old and developed a leak between the tankless flange and the casting. Our oil burner man (who is not the person who installed the boiler) never liked the boiler and said that it was risky to try to repair the unit and we might as well get a new boiler.

"Well dunkirk boilers falled to start again turn off breaker let sit one minute it starts i hope pipes are not frozen tec repla"
Tech says it's a good boiler. I think that is bs. I wish I have gotten a forced air because it failed to start again. I hope pipes did not freeze . This is the third time.

"This is important"
Replaced an old and reliable boiler for a small apartment building with a Dunkirk 90 200,000 btu boiler. I have had to replace 2 circuit boards within approximately 1 year of each other, the draft inducer and the ignitor twice. Something is terribly wrong with this picture. I am interested in other owners problems.

"Done with my Dunkirk Q90-100"
Bought my second home in 2007. q90-100 was installed in 2001 by previous owner. Have had 4 service calls when boiler was not working in cold weather. Spent over $1,000 plus repairmen gave me freebie hours trying to figure problems. Replaced circulator, purged system, etc. In January 2010, boiler gasket blew and water-antifreeze leaked through condensate tube. This boiler is scary because you never know if it will work. No pipe freezing . . . yet. Decided to skip the warranty claim and go with another brand. Wish me luck!!

Problems from day one, blower noisy, vacuum lines left open from factory, condensate line clogged from metal shavings, metal shavings on burner caused bad ignition by shorting spark from ignitor. Bad fitting on return which leaked. Tappings plugged from factory are starting to leak, main electronic board going bad keeps shutting off with 05 error code. And this is all within 4 months. Haven't seen any savings. The 95% is rated for radiant heat and temps of 120. When you have baseboard heat, you need 190 then the ratings drop into the 80'S. Any savings you do get will most likely be lost in repair bills. Customer service from sales rep was bad, supply house didn't have parts. Stay with a basic boiler.
