An unvented infra-red heater is designed to provide efficient radiant heating in spaces where ventilation might be limited or unnecessary. These heaters work by warming objects and people in their immediate vicinity, rather than heating the air itself, which makes them suitable for various applications.

In a warehouse setting, the ability to deliver targeted heat to work areas without the need for ducts or extensive ventilation systems allows for improved comfort and energy efficiency, making it an ideal choice.

In commercial buildings, such as retail spaces or workshops, unvented infra-red heaters can effectively provide warmth to customers and employees, enhancing the experience and productivity while keeping operational costs lower.

Moreover, in industrial buildings where open spaces are common, these heaters can be used to efficiently heat specific areas where workers are active, again without requiring additional venting.

This versatility across different types of buildings underscores the suitability of unvented infra-red heaters in all these applications, which justifies the answer being all of the above.
