How many years does radiant heat last?

Could you please elaborate on the longevity of radiant heat? I'm curious to know how long it typically lasts, and if there are any factors that can affect its duration. Is it a sustainable source of heat, or does it require periodic replacement or maintenance? Additionally, are there any alternative heating methods that might offer a longer lifespan? I'm interested in understanding the full scope of options when it comes to heating systems.
