Genuine Bosch secondary heat exchanger, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Secondary Heat Exchanger on Your Bosch 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 Bosch systems — including models such as Greenstar, Greentherm, Tronic — a failing secondary heat exchanger often shows up as ea no flame or related symptoms. We diagnose it precisely and install the correct genuine Bosch part.
