The Secondary Heat Exchanger on Your Rinnai 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 Rinnai systems — including models such as i-Series i090, i120, M-Series — a failing secondary heat exchanger often shows up as error 11 no ignition or related symptoms. We diagnose it precisely and install the correct genuine Rinnai part.
