What part of an oil tank installation must be protected from falling snow and ice?

In the context of oil tank installations, it is essential to protect certain components from environmental factors such as falling snow and ice. The primary concern is to ensure that the tank piping and valves are safeguarded since these components are critical for the system's operation and integrity.

If tank piping and valves are exposed to snow and ice, several issues may arise, such as blockages, leaks, or damage due to the weight of snow or the possibility of freezing. Protecting these parts helps to maintain a reliable heating fuel supply and reduces the risk of operational failures in the heating system.

While other parts of the installation, like the tank legs, the entire tank structure, and specific components like the oil filter, are also important, ensuring the integrity and functionality of the piping and valves is paramount because any disruption in their performance can lead to fuel delivery problems or hazardous situations. Thus, safeguarding the tank piping and valves from falling snow and ice is essential for the proper, safe, and efficient functioning of the oil heating system.
