for the tip. We've got a Dunkirk on order, our first steam job using that brand. I'll be sure the installers use both sides!

Dunkirk boilers

Dunkirk has been around for 75 years and is now part of the ECR International group of companies. The traditionally marketed their products as an OEM for companies like sears, Carrier and Lennox. So if you've heard of them they're Dunkirk boilers. You can find em at www.ECRinternational.com. Hope this helps.

Have some Dunkirk steamers in place.....

and they are working well. They are a boiler with fairly large side tappings, so when installed with a good piping layout, allow exceptional access to the inside of the boiler for cleaning and inspection at both ends of the top and bottom. The chief disadvantages I see are again the side tappings, they put the water in the boiler very close to the outlet so water can be easily drawn out and the push nipple openings between the sections are small, so I would think steam does not move through the boiler easily, something very different from the big old boilers that work so well with steam.

Proper piping is the key, as with any brand of boiler. Out of the 20 or so newer steamers (under 30 years old) I've seen in the past few years in my area (steam is not common here in Illinois, outside Chicago), about 19 were not piped properly. When using the 187.5 mbh size Plymouth and up I would definitely use both tappings for best performance, even though Dunkirk doesn't require it.

we only use dunkirks

they have 4'' tappings on their commercial sizes that allows for large low velocity piping,,always use both tappings,,keeps the exit speed down..we have not had any problems with dunkirks, either the residential or commercial ones. we like them alot..
