The Hot Surface Igniter on Your Bosch Boiler

The hot surface igniter (HSI) is a silicon-nitride or silicon-carbide element that heats until it glows, igniting the gas at the burner. HSIs are fragile and degrade with each cycle; a cracked igniter is a very common no-heat cause.

On Bosch systems — including models such as Greenstar, Greentherm, Tronic — a failing hot surface igniter often shows up as ea no flame or related symptoms. We diagnose it precisely and install the correct genuine Bosch part.
