Common Boiler Repairs: Keeping Your Heating System In Top Shape

Posted on

A boiler is an essential component of a home's heating system, providing warmth and comfort during colder months. Like any mechanical system, boilers may require repairs to maintain their efficiency and functionality. This article will explore some common boiler repairs and the steps homeowners can take to address these issues.

Leaking Boiler Issues

A leaking boiler is a common issue that can result from several factors, such as corrosion, damaged seals, or a faulty pressure valve. Identifying the source of the leak is crucial to determining the appropriate repair. 

In some cases, replacing a seal or valve may resolve the issue. However, if the leak is due to corrosion, the boiler may require more extensive repairs or even replacement.

No Heat or Hot Water Troubles

A boiler that fails to provide heat or hot water can be frustrating and uncomfortable. This issue can result from various causes, including a faulty thermostat, broken diaphragm, or malfunctioning heating elements. 

A heating technician can diagnose the problem and recommend the necessary repairs, which may involve replacing the faulty component or adjusting the system settings.

Kettling Complications

Kettling is a term used to describe the buildup of limescale or other mineral deposits inside the boiler's heat exchanger. This buildup can cause water to overheat and create steam, resulting in a noise similar to a boiling kettle. 

Kettling can reduce the boiler's efficiency and increase the risk of damage. The issue may require flushing the system and descaling the heat exchange.

Pilot Light Problems

The pilot light is a small flame that ignites the gas in the boiler's burner. If the pilot light goes out or fails to stay lit, the boiler will not produce heat. Common causes of pilot light issues include a faulty thermocouple, a dirty pilot light orifice, or a problem with the gas supply. 

A heating technician can easily restore a pilot light if it's gone out. They also can adjust anything that's causing the light to malfunction. Because pilot lights usually burn a small amount of gas, non-trained personnel shouldn't attempt to fix this.

Boiler Lockout Concerns

A boiler lockout is a safety feature that shuts down the boiler when it detects a problem, such as low water pressure, high flue temperature, or an air blockage in the system. If your boiler goes into lockout mode, repairs may involve adjusting the system's settings, replacing a faulty component, or addressing an air blockage.
