Halogen heating is popular with users because it provides an instant warmth as it warms up the body rather than the air temperature. 

The heat from a halogen heater is a radiant heat, which is similar to the heat we obtain from the sun. This form of heat warms the body faster than other forms of heat, making halogen heaters particularly useful in really cold areas like workshops / sheds / conservatories / warehouses.

The warm glow of the heater also makes people feel warm just like a log fire does.
