Product Testimonials

  • Yes, straight forward installation, explicit manual and installation directions, very good commissioning programming and especially great technical help.

    Tom Lowrie
    West Abington Twp., PA
  • Very convenient.

    Mark Yetto
    Amherst, NY
  • I found this unit very quiet hot water is plenty And the heat time will tell. As we enter the heating season the test did supply hot water to the baseboards the longer duration and propane use will be the judge. I have all the confidence it will.

    Charles Eckelmann
    Otego, NY

  • I have dealt with Dunkirk for a few years now and overall I believe they have quality products.

    The installation Manual for the DCC-150 is not laid out very well and can be hard to follow/understand at times.

    Brady Lindblom
    Coldwater, MI
  • Highly efficient. Very affordable! By all appearances, great quality!

    Coryville Church of Faith

  • Coaxial vent piping became a problem when we needed to offset based on customer expectations. We needed 3- 90's, and supplier only stocked 2. Then, the piping we receiving had some dents and dings. The inner support has broken in shipping, and the ends were crushed a little. We were able to straighten out with channel locks, but this should not be required.

    Gretchen Donnelly
    Pittsburg, PA
  • I install many boilers and always recommend DUNKIRK.

    JCCM Heating & Plumbing
    Auburn, NY
  • Customer service was excellent, boiler is very efficient and I love the way I can set the boiler to different btu parameters. Installation instructions are vague in regards to initial setup. If the zones are small, it knocks the boiler out on high temp.

    Kieran
    Yonkers, NY
  • The price was great for all the features and quality.

    Greg
    Northhampton, PA
  • I think it is a good product. The heat manifold and the domestic water manifold need to be offset.
