What is the reason low pressure steam is used for comfort heating?

Low pressure steam is primarily used for comfort heating because it has higher latent heat content. Latent heat refers to the amount of heat energy contained within steam that is released when it condenses back into water. This property allows low pressure steam to transfer a significant amount of heat to the surrounding environment when it condenses within heating systems, providing efficient and effective heating.

Using low pressure steam, especially in residential and commercial heating systems, is advantageous because it allows for consistent and comfortable heat distribution. The higher latent heat content means that less steam is needed to achieve the desired heating effect, improving energy efficiency and comfort.

Other options do not directly address the specific benefits tied to the use of low pressure steam in comfort heating. While cost considerations and control mechanisms are important in heating applications, the primary reason for using low pressure steam is its ability to carry and release large quantities of heat efficiently.
