Does the boiler require inspections? How often? What is the blue sticker?
According to the new regulations, boilers must be inspected the 4th year following installation, and then every 2 years.
- The inspection known as the Bollino Blu, or blue sticker, includes an analysis of the exhaust fumes and a report that is sent to the relevant authorities.
- Boiler maintenance, however, includes a series of annual checks on the boiler and parts of the system near the boiler.
