Common Boiler Issues and How Our Heating Engineers Can Help

Some of the most frequent problems we attend to are boiler breakdowns causing a lack of heat or hot water. This can result from several factors, including a faulty thermostat, broken diaphragm, failed motorised valve or issues with the gas supply. Our heating engineers provide thorough diagnostics to identify the root cause and carry out precise gas boiler repairs to promptly restore the functionality of properties around Botley and Oxford.

A leaking boiler is a serious issue that can lead to system pressure loss and potential water damage. Most commonly, leaks originate from corroded pipework, a broken internal component such as a pressure valve or pump seal, or simply poor installation. Our team conducts meticulous inspections, replacing defective parts with high-quality components covered by our 12-month warranty.

A broken boiler often presents with low pressure, which can prevent radiators from heating up effectively. Low pressure is typically caused by a water leak in the system, a faulty pressure relief valve, or bleeding radiators without re-pressurising the system. Our heating engineers can quickly diagnose and re-pressurise systems in both domestic and commercial properties around Oxford and Botley, ensuring optimal efficiency.

During cold weather, the condensate pipe, which removes acidic water from your boiler, can freeze. This leads to the need for gas boiler repair, as a frozen pipe will usually cause the boiler to shut down as a safety measure. Our team expertly thaws frozen pipes and insulates them to prevent future occurrences, keeping your system running smoothly year-round.

If your boiler is making unusual noises such as banging, whistling or gurgling, it could indicate trapped air, a failing pump or limescale build-up, known as kettling. Our specialists perform thorough system flushes and part replacements to resolve noise-related issues effectively.
