Worcester GREENSTAR-29CDI-CLASSIC user manual

There could be several reasons why your Worcester heating is not working. Some possible causes include:
1. The thermostat is not set correctly: Check if the thermostat is set to the desired temperature and mode (heating).
2. Power supply issues: Make sure that the heating system has power. Check the circuit breaker or fuse box to ensure it hasn't tripped or blown.
3. Gas supply issues: If you have a gas-powered Worcester heating system, check if the gas supply is turned on and if the pilot light is ignited.
4. Faulty ignition: If your heating system has an electronic ignition, there might be an issue with the ignition switch or control module. This could prevent the heating system from turning on.
5. Blocked or dirty components: Over time, certain components of the heating system, such as the filters or vents, can become blocked or clogged with dirt and debris. This can lead to reduced airflow and poor heating performance.
6. Malfunctioning thermostat: The thermostat may need to be replaced if it is not functioning properly or if it is not communicating with the heating system correctly.
7. Faulty motor or fan: If your heating system uses a motor or fan to distribute hot air, a malfunctioning motor or fan could be preventing the system from working.
If you have checked these potential issues and your Worcester heating system is still not working, it is recommended to contact a qualified HVAC technician to assess and repair the problem.

The temperature you should set for your Greenstar CDI boiler depends on your personal preferences and the heating requirements of your home. However, a common recommendation is to set the thermostat to around 18-20 degrees Celsius (64-68 degrees Fahrenheit) for comfortable heating. It's important to consider factors such as insulation levels, weather conditions, and energy efficiency goals when determining the ideal temperature setting.
