When should hot water piping in buildings be maintained at the design temperature?

  1. During winter months only

  2. During summer months only

  3. During high occupancy periods only

  4. At all times using a self-regulating heating cable

The correct answer is: At all times using a self-regulating heating cable

Hot water piping in buildings should be maintained at the design temperature at all times using a self-regulating heating cable. This ensures that the hot water remains at the specified temperature regardless of external factors such as weather or occupancy levels. Using a self-regulating heating cable allows for precise temperature control and prevents issues such as freezing or overheating, which can occur if the temperature is not regulated consistently.
