How do far-infrared heaters work?

Far-infrared heaters convert electricity into radiant heat, which provides the same warming effect as the winter sun on your face or the heat emanating from an open fire. It is even the same kind of heat that your own body emits. It is the most fundamental type of heating known to humanity.

Efficient heat transmission

Far-infrared heaters don’t warm the air around you; instead, they transmit energy waves directly to the target. Similar to the warmth we experience in a solar-heated atmosphere, this is the wavelength that the human body absorbs the most readily. You may be sure that it is entirely safe and natural.  Modern technology has enabled us to utilise far-infrared radiant heating efficiently.

Far-infrared heat is just right for humans

Human bodies absorb and emit electromagnetic radiation. As a result, our radiant heat gain or loss determines more than 60% of our perception of comfort or discomfort. On the other hand, air temperature and movement account for just 15% of our sense of comfort. Consequently, we feel hot when our bodies actively receive heat from our surroundings and chilly when we release heat to the outside world.

Most of us experience discomfort when our core body temperature rises above 26 °C or falls below 16 °C, respectively. Therefore, if we warm the room we are in (not the air) to at least 17 °C, and preferably to approximately 22 °C, our bodies will stop feeling that they are losing heat, and we’ll feel warm and comfortable. Far-infrared heating aims to create “thermal mass” in a space, thereby keeping you warm.

Is infrared heating effective?

Even the finest low-consumption “smart” electric convection heaters need more energy input to maintain adequate heat absorption by the environment and its inefficient energy transmission back out.

Far-infrared panels from Infracomfort do not heat the air and often are specified at wattages per sq/m far less than convective or air-to-air systems.

You may think that a kilowatt of energy released by convection or radiant heaters must contain the same heat transfer qualities, but this is not the case. Radiant heat has a greater heat transmission rate per kilowatt than convection; hence, less of it is required. Air is not a great transfer of heat.

Infracomfort and electric convectors both operate for around forty per cent of the needed heating time (often referred to as the “effective power”). Nevertheless, because of the essential difference in heat transmission, Infracomfort heaters might save you up to 50% on power expenses compared to convection heaters.

See how far-infrared compares to heat pump technology when all expenses — buying, installation, operation, maintenance, and replacement — are considered over the heater’s lifetime. Infracomfort far infrared heaters have a 30+ year anticipated term of life.

In a nutshell

  1. Far-infrared heaters convert electricity to radiant heat like the sun or open fire.
  2. Far-infrared heaters are safe and natural by transmitting energy waves directly.
  3. Far-infrared heat is fundamental and comfortable for humans.
  4. Radiant heat requires less energy as it has a higher heat transmission rate per kilowatt compared to convection heaters. Infracomfort heaters can save up to 50% on power expenses.
  5. Infracomfort far infrared heaters last over 30 years, making them more cost-effective than heat pump technology.

    The flexibility of Infracomfort far-infrared heating makes it the ideal choice to suit the many different room sizes and living spaces found in homes, schools, communities, workplaces and commercial buildings throughout New Zealand.
