What is the best type of radiant heater?

Could you elaborate on what you mean by "best" when it comes to radiant heaters? Are you looking for efficiency, cost-effectiveness, safety, or perhaps a combination of these factors? Additionally, it's important to consider the size of the space you're looking to heat, as different types of radiant heaters may be more suitable for larger or smaller areas. With so many options available, it's crucial to weigh the pros and cons of each type to determine which one would best suit your needs.
