Infra-red ray's do not give heat merely when they come into contact with something the infra-red (light) energy is converted into thermal energy
Instruments for detecting infrared radiation include heat-sensitive devices such as thermocouple detectors, bolometers, photovoltaic cells, and photoconductors.Pranay karnatak
Normal LED lamps produce almost no infrared light. However, just like there are LEDs in various colors like red and green, there are also infrared LEDs.

-- radio -- heat -- infrared -- ultraviolet -- microwave -- X-rays -- gamma rays -- cosmic rays
The Sun emits heat in the infrared wavelengths. The sidewalk is warmed by those direct rays.
The warmth you feel come from the Infrared rays.
infrared rays
The infrared quartz heaters have the infrared emitters and they emit infrared rays continuously to heat the heater in the instrument. The heat is generated and infrared emission stops.

Heat
Infrared means heat. It depends on what wattage or ampage the light is.
No, they are not bad at all. Infrared rays are long wavelengths that supply heat and are often used therapeutically to warm tissues before and during thermotherapy.
