An infrared heater reaches the maximum capacity within seconds, rapidly generating heat in its radiant heat-transfer area.

It does not heat the air, but objects, surfaces and bodies in its radiating area, which then give up heat and warm the space.

An infrared heater can cause so-called thermal discomfort as rays only heat one part of the room while the other part remains cooler.

An infrared heater is suitable for places where there is no need to warm the entire space, but only the part where the person is staying, such as in the garage and on the veranda.
