The unit was installed around 2005 with the other owner of the house. The system has failed time and time again, while replacing parts and overhauling numerous times! Does anyone have a suggestion of another company/unit that has a similar hookup (using propane) that is less expensive? Thanks…

"Installation is key"

We are professional, licensed contractors in Upstate New York. We've installed several of NY Thermal's Trinity boilers as well as other manufacturer's boilers. Our oldest install of a Trinity is over 12 years old. Our experience is that the Trinity boilers or no worse or better than most other manufacturer's mod/con boilers. Overwhelmingly, the problems we have found with all brands of mod/con boilers is installation. And it's not any one single thing. Units with undersized gas piping, not using primary/secondary piping, not understanding how primary/secondary piping works, outdoor sensor not connected or sometimes not even installed, undersized circulator pumps, etc. You name it, we've seen it. I notice several complaints about the cost of parts. That isn't unique to NY Thermal. Most mod/con boilers have primarily OEM specific parts. They are expensive and sometimes expensive to install. In short, make sure your contractor knows how to install a mod/con if you decide that's what you want. Ask them for pictures of previous installs and referrals from previous customers they've installed mod/cons for. Ask what classes they've attended or training they've had specific to mod/con boilers. For every problem we see that is a fault of the boiler, we see a minimum of 10 that are install related.

If you want to overspend, Viessmann is the best made boiler on the market. NTI, however, is probably your best buy. There was some learning to be done on the original T series, but since then the boilers are a solid investment. The Ti series is mostly trouble free. We may replace an ignitor after five years, iron a probe or sensor, but otherwise they have been very reliable. The new Tx series, the oil boilers, have all been great. But, if not installed and maintained correctly, any condensing boiler will give you trouble. Our business as it pertains to NTI is installing and maintaining, and correcting issues created by installers who can't or won't read installation manuals. It's really not too difficult. I have one in my house and one in my shop.

I had my NTI Trinity 100 installed Feb 2010 and it has underperformed every winter. During cold days it is unable to keep the house warm at 72 and starts to drop down as low as 65. I relied on the salesperson to recommend the right model. I was finally told by the repairman now, 5 years later, it is undersized. When it was installed I had the repairman out at least 4 times as it was not performing. His answer was to disconnect the outside sensor. It did perform a bit better after that was done but still poorly. I had the main circuit board go last spring ($800) and a week ago the water pressure sensor ($525) went. The repairman said all of these boilers were failing and the newer models had some of the issues fixed. My problem is I am stuck with a very expensive piece of garbage. If you are considering buying…don't.

"Excellent boiler, highly recommended."

We have a three-zone radiated heating system, and were having problems with our previous boiler failing to heat the house. With some guidance from our heating guy, we decided to replace the old boiler with the NYT Trinity Ti100 about 2-1/2 years ago. We have not regretted it. The new boiler is about a third the size of our old boiler and far more efficient and cost effective. We saw an immediate impact on the natural gas portion of our utility bill in spite of a colder than normal winter that year. As a side benefit, a recurring problem with loudly banging pipes vanished; we haven't had to bleed our radiator pipes since it was installed. The only drawback is that it is not even more efficient, but that is an issue of our budget constraints and definitely not a problem with the boiler. For the money, the value is definitely there. I would recommend this boiler to a friend without hesitation.
