How Herschel far infrared heating works

Far infrared is radiant heat, it’s the same as the feeling of warmth from the sun on your face and the heat from a coal fire. It is even the same form of heat emitted by your own body.

It is the most basic form of heating known to man. Used by cavemen to heat themselves by fires; by Romans in their hypocausts, by log burners and tile stoves. Favoured for millennia because it heats objects, which then radiate back and keep the environment warm around you. Radiant heat does not heat air – which holds little heat and disappears.

But in the last 60 years, we have forgotten about radiant heating: not because a better technology replaced it, but because fossil fuels that powered central heating made it so cheap to heat air.

Today, new technology, in the form of our 100% energy efficient Herschel far infrared heating panels, is allowing us to use radiant heating once more in a stylish, comfortable and highly controllable way.


  • What is Infrared Heat?

    What is Infrared Heat?

    Feeling warm or cold does not depend on the temperature of the surrounding air. For example, skiers and mountain climbers do not freeze even in extremely cold, but sunny, air. They are bathed by rays from the sun, which include infrared. We experience this heat directly on our skin and by rays reflected by the environment (snow, stones, earth etc.). When infrared waves touch a surface, heat energy is released regardless of the surrounding air temperature

    Heat Transfer Fundamentals: radiant heat versus convection heat

    In terms of heat transfer efficiency, radiant heat and convection heat simply do not compare. They have very different heat transfer properties and as far as heating your home, office or workspace goes, it is important to know the difference. Radiant heaters heat objects in the environment which warm up and radiate back. Convection heaters heat air, which retains heat poorly and disappears on draughts.

  • Human Factors in Comfort Heating

    Human Factors in Comfort Heating

    Why can you still feel cold in a centrally heated room? Because central heating does not warm up objects in a room, only the air, the walls and other objects in a room remain cold. If you are sat with your back to a wall at 17°C you will be radiating out your own body heat to that wall, even if the air temperature is 21°C. Learn about “Mean radiant temperature”: a key component of comfort, and something that central heating does little to address.

    Preferred Wavelengths for Comfort Heating

    Water – which comprises 80% of human and animal skin absorbs most efficiently from 3 microns and lower which is Far Infrared (longwave). This implies both people and animals can be warmed effectively and comfortably and effectively by the correct use of Far Infrared, not Shortwave (Tungsten Halogen) or Medium wave IR (Quartz).

    Different Types of Infrared

    It is critical to use the right type of heater in commercial, public and domestic heating scenarios. Underspecified, the wrong heater will just feel ineffective. Overspecified, it can cause extreme discomfort.

    Infrared and buildings

    Infrared heats objects, not air. So objects remain relatively warmer than the air and condensation is avoided. Central heating warms the air and not the fabric of a building – conditions that encourage condensation. It is a little remembered fact of pre-centrally heated houses that maintenance periods were fewer and further between. Learn about the advantages of infrared in buildings when used to refit and old system or in brand-new builds; and learn about its suitability for solar.
