What is one of the main benefits of using a vacuum system compared to traditional systems?

One of the primary advantages of using a vacuum system is that it allows for condensate to be lifted without the need for pumps. In traditional steam systems, condensate, which is the liquid formed when steam cools, usually relies on gravity or pumps to return to the boiler. However, in a vacuum system, the reduction of pressure inside the system lowers the boiling point of water, enabling condensate to flow back toward the boiler naturally due to the pressure differential. This mechanism simplifies the system design and reduces the need for additional pumping equipment, which can lead to lower operational costs and increased reliability.

While options regarding maintenance, heating speed, or installation costs might present certain advantages in different contexts, they do not highlight the unique operational efficiency provided by vacuum systems concerning condensate management.
