NTI was founded by Malcolm Dennison as NY Thermal Inc. in Quebec, Canada, originally manufacturing steel fireplaces. Over time, the company shifted its focus to hydronic heating equipment, eventually becoming one of Canada's most respected manufacturers of high-efficiency boilers and water heaters. The NTI name has become synonymous with quality craftsmanship and innovation in the residential and commercial heating industry across North America.
NTI's engineers strive to set new standards for high-efficiency gas boilers, water heaters, and combi furnaces. Acknowledged as a leader in research and product development, NTI manufactures its top-quality hydronic products in accordance with the most advanced guidelines and industry codes. The company's product lineup includes residential and commercial gas boilers, water heaters, combi furnaces, indirect-fired water heaters, and oil and wood-fired boilers, offering solutions for a wide range of residential and commercial applications.
What has long distinguished NTI from its competitors is a customer-first philosophy. NTI listens to its customers and uses their feedback to guide innovation, while its knowledgeable and accessible staff support every customer to maximize product performance.
In 2016, Ariston Thermo of Milan, Italy, acquired a controlling interest in NTI. Ariston Thermo is a global group with a full range of products, systems, and services sold in over 150 countries, with 20 production sites across 12 countries, offering solutions under brands including Ariston, Elco, Chaffoteaux, and Atag Heating. Despite the change in ownership, NTI has continued to operate under its own brand and maintain its manufacturing presence in Saint John, New Brunswick, preserving its identity as a proudly Canadian-made product.
