The Heat Exchanger on Your Vaillant 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 Vaillant systems — including models such as ecoTEC plus, ecoTEC pro, ecoFIT — a failing heat exchanger often shows up as f22 low water or related symptoms. We diagnose it precisely and install the correct genuine Vaillant part.
