Which of the following is an advantage of steam heating systems?

Steam heating systems are particularly advantageous in their ability to efficiently transfer energy over considerable distances, which is a key factor in their functionality, especially in taller buildings. When steam is generated, it carries a significant amount of thermal energy, which can be distributed through pipes to various points within a structure without significant temperature loss. This capability allows steam to maintain its efficiency even as it travels up several stories, making it ideal for larger and taller buildings.

The physical properties of steam contribute to this efficiency; steam has a high thermal carrying capacity, meaning it can retain and deliver much more heat compared to other heating mediums like water. This characteristic enables steam heating systems to effectively warm areas that are far removed from the heat source, irrespective of the height of the building. As a result, buildings with multiple stories can benefit from consistent and effective heating throughout all levels without a decrease in performance.

In contrast, the other options presented highlight disadvantages or misconceptions about steam heating systems. For example, energy loss is generally less significant in steam systems compared to other heating methods, the ability to transfer energy over distances is a strong advantage rather than a limitation, and steam heating systems actually possess a high capacity for energy transfer.
