NTI Secondary Heat Exchanger Replacement in Greater Vancouver

Genuine NTI secondary heat exchanger, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.

The Secondary Heat Exchanger on Your NTI Boiler

The secondary (or condensing) heat exchanger sits in the flue path of high-efficiency boilers and extracts additional heat from the exhaust gases before they leave the appliance. It is where flue-gas condensation forms, so it operates in a wet, mildly acidic environment and is prone to blockage and corrosion over time.

On NTI systems — including models such as Trinity Tft, Trinity Lx, TX Series — a failing secondary heat exchanger often shows up as ignition failure or related symptoms. We diagnose it precisely and install the correct genuine NTI part.
