Product Testimonials

  • Yes , the boiler is pretty compact for an oil fired boiler. It also seems to be very efficient in overall fuel consumption. Even though we had an issue with the riello burner not firing right out of the box, the vendor provided us with another burner right away which worked flawlessly.

    The one thing I found a little trouble some is the fact that the supply, return , and flue are all out the rear and in a row or “stacked”. This forced us to offset the flue pipe and the return riser .

  • So very pleased with the boiler. Very impressed with the size and efficiency compared with the 70 year old boiler I just replaced. I hope your product lasts just as long! :)

    Steven Walsh
    Farmington, CT

  • Yes. Furnace not huge, so takes up less space than old one; great deal more efficient than old one; price did not "break the bank".

    Laurel Hankins
    Newville, PA

  • They are quality and dependable products.

    Richard Snell
    Camden, NY

  • very small compared to original.  Looks well built.

    Mike Palermo
    Wallingford, CT

  • Nice clean unit.  

    Mike O'Sullivan
    New Hartford, CT

  • Absolutely recommended.  We have been installing Uitca Boilers for nearly 25 yeas with great success.  I wish the SSC model could be produced as a combi.  Even an add-on would be nice.  The heat exchanger in the SSC is typically trouble free.  I still swear by cast iron oil products.

    Edward Keenan
    Gansevoort, NY

  • Very well built and easy to install.

    Russell Wiediger
    Sauquoit, NY

  • Yes I would reomment your prodcut.  I have heard from the Oil Service Company that they have had very good luck, with almost no failures in the equipment that they have installed in over 15 years. That is what you want from a boiler. Just run when I need you.

    Chris Granatini
    Marlborough, CT

  • Great product straight forward installation.

    Michael
    Folsom, PA

  • TRB and H2O Indirect - It's a great combination of equipment. The feature and options surpass my expectations.

    Philip

  • The utica trifire is the best oil boiler ever designed, top of the line product

    Hoffman & Miller
    Amsterdam, NY

  • Easy install, fairly quiet, and good service center.

    Mike
    Broadalbin, NY

  • "Yes, I would recommend Utica Boilers to a friend because of the quality of the product at the price point. I was considering a High Efficiency Peerless or a Burnham Boiler. My contractor strongly recommended Utica Boiler brand. I am glad that I followed his advice!"

    Bob
    Wappingers Falls, NY

  • YES ! I've installed Utica boilers over 30 years & have never had an issue. We removed an old boiler from 1948 that took almost 2 hrs to heat up from a cold start. We installed the new TRB5100 & in 4 min, from a cold start was returning warm. Can't wait for this customer to report back next year with how much oil he saved!

    Carroll E Harris Heating & Cooling Inc

  • YES I WOULD. I SAY THIS BECAUSE ITS WHAT THE NORTH AMERICAN MARKET NEEDS.THE TRB IS A LOW MASS ,WELL INSULATED ,THREE PASS BOILER. I COMBINE IT W/ AN OUT DOOR AIR INTAKE AND A VARIABLE SPEED CIRCULATOR AND IT MAKES FOR A VERY EFFICIENT PACKAGE.
