NTI: Canadian Boilers Built for Canadian Winters
NTI is a Canadian boiler manufacturer based in Saint John, New Brunswick, producing high-efficiency condensing boilers engineered specifically for cold-climate heating. For Lower Mainland homeowners, that pedigree matters: NTI's stainless-steel fire-tube heat exchangers, deep modulation, and 95–96% AFUE efficiency are designed around exactly the kind of long, damp heating season Greater Vancouver gets from October through April.
The NTI lines we install and service most are the TFTN (Trinity Fire Tube) heating-only series spanning 85,000 to 399,000 BTU/hr from single-family homes up to light-commercial loads, the FTVN fire-tube condensing series, and the TRXcondensing combi line that delivers space heating and domestic hot water from one wall-hung unit. Premium NTI lines carry a limited-lifetime heat-exchanger warranty — among the strongest in the industry.
Our Red Seal–certified gas fitters install, repair, and maintain NTI equipment across the Lower Mainland, verify every repair with a digital combustion analyzer, and carry common NTI components — igniters, flame electrodes, sensors — on the truck so most repairs finish in one visit.
