Boiler operates but energy consumption seems unusually high

Safety first: Adjust only user-accessible settings unless you are trained to change installer parameters.

Steps to check:

• Lower setpoints: Reduce the heating flow temperature to the lowest value that still provides comfort.
• Enable optimization: If your Kospel boiler supports weather compensation or eco modes, enable them according to the manual.
• Check schedules: Ensure heating and DHW schedules are not set to 24/7 operation if not needed.
• Insulate system: Insulate exposed pipes and ensure the building envelope is adequate to reduce heat loss.

When to call a technician: A professional can optimize boiler parameters and check combustion efficiency (for gas models).
