Signs That Your Gas Boiler Needs Servicing

Gas boiler warning signs

While regular servicing is recommended, there are certain signs that indicate your gas boiler may need immediate attention. These signs include:

  1. Unusual noises: If you notice strange noises coming from your boiler, such as banging, whistling, or gurgling sounds, it could be a sign of a problem. These noises may indicate issues with the burner, pipes, or other components, which should be addressed by a professional.
