What should I do if my Viessmann Atola Series ECV Boiler is not heating properly?

Check the thermostat settings and ensure they are correctly configured. Inspect the pressure gauge to confirm it is within the recommended range. If issues persist, consider bleeding the radiators or contacting a professional technician.

How often should I service my Viessmann Atola Series ECV Boiler?

It is recommended to service your boiler annually. Regular maintenance can help ensure efficiency, safety, and reliability, and can prevent potential issues.

What is the correct pressure level for the Viessmann Atola Series ECV Boiler?

The ideal pressure level for optimal performance is typically between 1.0 and 1.5 bar when the system is cold. Check the user manual for specific recommendations and adjust using the filling loop if necessary.

Why does my Viessmann Atola Series ECV Boiler make a loud banging noise?

This could be due to a phenomenon known as 'kettling', which is often caused by limescale build-up or air trapped in the system. It is advisable to contact a qualified technician to investigate and resolve the issue.

How can I improve the energy efficiency of my Viessmann Atola Series ECV Boiler?

Ensure regular maintenance, keep the system clean, and consider installing a programmable thermostat. Additionally, insulating pipes and bleeding radiators can help improve efficiency.
