Pilot-model ignition failure
Older pilot-ignition Highflow units can lose the pilot in gusty weather, particularly in exposed positions. Newer electronic-ignition models removed the problem entirely.

About the brand
Bosch has supplied instantaneous gas water heaters worldwide for decades, with a strong presence in Australian continuous flow installations.
Warranty, in plain terms
Continuous flow heat exchangers typically carry longer cover than other components; licensed installation and correct gas sizing are required.
Parts we carry
Igniters, water valves, sensors and flue components for common Bosch units.
Typical lifespan
Bosch continuous flow units regularly run 15–20 years when serviced; the electric storage range follows the usual 8–12 year pattern.

Common Bosch faults in Perth homes
Scale on the heat exchanger
Shows as reduced output and fluctuating temperature. How quickly scale builds depends on local water quality and how hard the unit is worked.
Water valve and sensor faults
Unit runs hot then cold, or won't modulate. Usually a stocked sensor or valve rather than a heat exchanger issue.
Flue termination non-compliance
We regularly find older Bosch units with flue terminations too close to a window or under an added deck — corrected at service or replacement.
When replacing beats repairing
A cracked or leaking Bosch heat exchanger out of warranty is the replacement trigger. Ignition, sensor and valve faults are worth repairing on almost any age unit.
Our repair or replace guide sets out the full decision, and the Perth replacement cost guide explains what changes the price. Symptoms are covered in common hot water problems and the hot water FAQ.
