Dunkirk Heat Exchanger Replacement in Greater Vancouver
Genuine Dunkirk heat exchanger, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Heat Exchanger on Your Dunkirk Boiler
The primary heat exchanger is the heart of your boiler, transferring heat from the burner flame and combustion gases into your heating water. In condensing boilers it is usually stainless steel or aluminium; in cast-iron and conventional boilers it is the boiler block itself. A cracked, blocked, or corroded heat exchanger is one of the most serious boiler faults — it can cause flue-gas leakage, internal leaks, and loss of efficiency.
On Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing heat exchanger often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
