Corporate History

NTI was formed in 1968. It was originally known as the New Yorker Boiler Co., then NY Thermal Inc., and is now known as NTI. NTI boilers are manufactured using computer-assisted design techniques at the company’s 72,000 square foot waterfront facility which also includes a laboratory and training facility.

Product Lines

NTI’s line of 5 Energy Star qualified gas boilers includes the 95% AFUE Vmax and 4 Trinity units – the Tft, Tx, Ti, and Lx. These high-efficiency boilers are designed to meet nearly every need. Options for the various products include wall-mounting, use of natural gas or propane, quiet operation, versatile venting and availability in combi versions.

In addition, NTI offers oil-fired boilers, including the cast iron Odyssey, high-efficiency Caprice and hot water Triton. Also available is the WF series wood-fired boiler, which is designed to run with an existing oil burner.


NTI offers a basic 5-year warranty on all parts and components, including the pressure vessel, on boilers and water heaters. The cost of labor is not included.

As most others have already said…Most unreliable system ever. Don't waste your time or money on NTI. Very expensive to fix and trust me it will break down! I would never buy this brand again and will discourage anyone else from doing the same. It really is too bad since the company is Canadian…



"Nti boiler"

Very Unsatisfied

Our NTI boiler was fired up December 8, 2016 and we lost domestic got water on Sat (May 13/27). Getting parts are a nightmare might be here Friday. And we are not guaranteed it will even be covered under warranty. Like in on a farm in SK with no hot with a family of 4 is maddening. I hope it's resolved quickly. Angry farm wife.

"It's obviously the installers not knowing how to install the boiler."

5.0 rating
Very Satisfied

I am a professional hydronic installer. I have installed over 400 of these boilers in large and small houses. None of them have ever had a problem. When installing boilers, proper knowledge of primary and secondary piping, zoning, buffer tanks and mixing valves is a must. If your installer advertises that he installs furnaces as well, run. Boilers are the Lamborghini of heating you wouldn't have a Ford dealer work on a Lamborghini. So why have a furnace guy install your boiler? You're asking for trouble.



"Terrible product, worse customer service."

1.0 rating
Very Unsatisfied

Words cannot begin to express my loathing for this product. I know full well that many of the problems we've experienced were because of poor installation. However, major parts routinely failed despite servicing twice a year and good luck getting parts in a timely manner. The absolute worst customer service I've ever encountered. Over five years, we have doubled up the original price with repair costs. We are now completely replacing having decided to finally stop digging. Please, please don't buy this boiler.
