FAQs
What are the most common problems with gas heaters?
Gas heaters can face several common problems, including:
- Water Does Not Heat Up: This problem may be caused by a fault in the thermocouple, which is responsible for monitoring the flame, or by an obstruction in the burner. In addition, a faulty gas regulator can also prevent the boiler from working properly.
- Water Heats Up Little: Usually caused by clogged burners that do not allow efficient combustion, inadequate gas pressure, or a faulty thermostat that does not regulate the temperature properly.
- Flame Goes Out or Doesn't Light: Problems with the ignition system, low gas pressure, or a faulty gas valve may be the cause. There may also be problems with the thermocouple not detecting the flame, resulting in automatic shutdown.
- Gas or Water Leak: It can occur due to corrosion in the connections, damaged valves, or wear and tear on the system. Gas leaks are particularly dangerous and must be treated urgently to avoid safety risks.
- Wear or corrosion: Over time, the heater may corrode the tank or connections, affecting the effectiveness and safety of the appliance. Corrosion can shorten the life of the boiler and cause malfunctions.
