Perfect boiler for my home with easy installation! My plumber suggested Dunkirk boilers for all of my properties and I could not be more satisfied. Installed last year, my plumber told me they were the easiest boilers he has ever installed. I have houses with multiple unit installations and the work was beautiful

Gas fired, cast iron steam boiler, has run with zero problems for 31 years. I am now concerned with age of unit and various controls, mostly Honeywell. Based on my experience I would purchase a new
Similar Dunkirk PSB-5D.

I do not recommend a Dunkirk. I have a Dunkirk boiler for 7 years now and all I have is problems. I have woken up so many morning with no heat it is not funny. The unit is constantly breaking down. I am on my 3rd mother board for the boiler. Fuses in the boiler blow. It is suppose to provide error codes so you know what the problem is and it does not even do that. I suggest looking at other manufactures for a new boiler since this one is not reliable boiler at all.

First boiler installed on November 9, 2012. It quit working several times. Pilot had to be re-lit numerous times. Pilot won't stay lit. January 19, 2015 Dunkirk service rep inspected boiler. Had to be replaced even though it was out of it's 1 year warranty. January 19, 2015 new boiler installed. Same problem within 6 months of new installation. Continuing to happen every few months. On November 11, 2017 stopped working and can't get pilot to stay lit. This is in a 4 unit apartment building, inconveniencing all tenants. I had to buy space heaters for all tenants. Problem after problem. Dunkirk doesn't want to help. Don't buy a Dunkirk!

First one rotted, it was falling apart when they removed it. The replacement died almost immediately and is now cracked. Junk junk junk
