What are replacement products?

Replacement products are specifically defined as new items that serve to substitute for old or outdated versions of a product. This concept is particularly relevant in fields such as building services engineering, where technology and equipment frequently evolve. The replacement products are designed to provide similar functionality or improved performance over their predecessors, accommodating advancements in safety, efficiency, or design.

In practice, when a component or system becomes obsolete or inefficient, it often requires a modern equivalent to ensure optimum operation and to meet current standards. This makes the understanding of replacement products critical for professionals in the engineering field, as it directly influences project decisions, cost implications, and service reliability.

The context for why other options do not fit is that decorative items focus on aesthetics rather than functional replacement, repair refers to maintaining existing products instead of substituting them, and used products sold at a discount do not fulfill the criteria of being substitutes for the old products in terms of performance and potential upgrades.
