"Great Boiler!"
I've had this boiler for over 16 years, and it's still going strong. It was installed correctly and I am very happy that I have it. I have never had any trouble with it, or had any maintenance on it or needed any.

"Its a keeper"
I installed this thing two years ago and couldn't be happier. My plumber talked me into this vs the high efficiency models. Trade off is about 5 to 10 points less efficient but a lot less headaches. As he said 10 things have to go right for those high efficiency models to even ignite and you need a $300 service call every year. This replaced another cast iron boiler that was probably 40 years old. The efficiency gains were more than noticeable. Only problem I had was the electric damper closing device. Had to replace it after a year but it was simple and free. I love this boiler and sleep well at night. It was very reasonable, professionally installed in under a day and at least 33% more efficient than what I had. I can see it in my gas bill.

"GAS VALVE NIGHTMARE"
In five years I have had to replace the Gas Valve Mechanical as of today five times. The system was installed the end of 2006. They sent me one new pump, but that went bad in one year. I sent it back to Utica today, with my feelings in writing. I hold "0" hope for their forwarding $375.00 to repair my gas fired boiler. This furnace has four igniters replaced, also.

"replacing a 20 year old Utica boiler"
I'm in the process of replacing a Utica boiler I had installed in our home 20 years ago. The current unit is working fine, but this is our retirement home and I plan on living in it for another 10 to 20 years and don't want to deal with a boiler that fails on its schedule instead of mine. We will replace it when it's nice and warm out and not during the winter in an emergency situation. A friend of mine who is a plumber tells me most boiler failures are due to faulty installation, and properly installed, hot water boilers are pretty free of trouble. That has been the case with our Utica boiler.

"Reliable"
The manufacturer date on my mgb1502h Utica Gas Boiler is dated 1987. I brought my home three years ago and have had no problems with this boiler. The last significant notes written on the boiler is dated 2/1994 regarding cleaning of pilot. All other notes refers to purging the system. Just before winter last year I took out the burners and clear them. I am thinking that due to age I may have to replace it with a high efficient model and I am looking to another Utica Boilers.
Other MGB Reviews
Homeowners and contractors around the web don’t seem very happy with the Utica MGB. In response to consumers’ troubleshooting problems, contractors on heatinghelp.com note several issues with the construction of the unit.
Certain elements of the MGB, such as lack of insulation around the boiler, frequent burn out from damper motor, counterintuitive system operation, and a difficult-to-repair heat exchanger, make this model a less than favorable choice, according to these contractors. Because of these issues, the professionals on heatinghelp.com recommend a different unit to homeowners shopping for a home heating solution.
In addition, consumers on heatinghelp.com note the lack of support from Utica. Several indicate they could not get the answers to seemingly simple questions—such as whether or not the unit has a dampener or the minimum and maximum flow rates of the unit—from the company.
