How Infrared Works

The Infrared Principle

Infrared electric heaters emit radiant heat from the front panel. This is a form of emit direct thermal radiation which you can feel. The feeling is very similar to the heat from the sun.

Unlike conventional heating systems, infrared heaters do not directly warm the air in the room. Instead, they heat up the surrounding structures, such as the walls, the floor and the objects in the room.

Infrared heaters emit heat radiation from the front panel. The Infrared waves are then absorbed by physical objects and bodies in the room. Making the room feel warm, while also creating a constant and mutual heat exchange between the room and objects.  This means that the heat is stored for up to 3x longer than heating methods which warm the air.

The feeling of radiant heat is what makes infrared heaters so popular. Heat / warm turbulent air does not move through the room; instead is it constantly emitted by surrounding surfaces close to the heater.

They generate an especially comfortable and healthy indoor climate. Heat does not move through the room; instead is it constantly given off by the surrounding surfaces.

Infrared electric heaters provide constant drying of the walls. Leaving very little chance for mould to grow. Also, there’s a reduction of dust circulating in the room, improving the air quality in the room.

Infrared heating systems can be installed on walls, ceilings or as an additional heat source!

Comfortable and Silent Heating

We like our home to be constantly comfortable without have to think about the heating.

Infrared heaters don’t produce a dry air feeling and are completely silent when in operation.  

Your heating system should warm the room quickly when needed. Then maintain that level of comfort, so you can sit back and relax.

Our Welltherm infrared heaters. provide this. One thing customers immediately point out is the feeling when stood near the heater.  They create a similar feeling to the heat from the sun. 

Health Benefits 

As infrared electric heaters primarily heat the objects and bodies in the room, they don’t create the dry air feeling typically associated with electric heaters – such as convector heaters.

In addition, infrared heaters don’t produce turbulent air. They don’t move dust or other particles around the room. Making infrared heaters ideal for people asthma or other breathing problems. 

The infrared heat radiation emitted by infrared heaters causes a constant drying of the walls. Preventing damp patches and mould from growing. 

Exclusive to Welltherm Heaters

Highly Efficient Heating Technology


ESHC technology is what sets Welltherm’s infrared heater’s apart from the rest. 

ESHC (Entire Surface Heat Conductor) is an innovative heating technology developed in Germany. Among the users of this technology are large German companies and important biotech companies. For example, used to dry tissue samples in pathology in order to examine them under the electron microscope. This application only allows a tolerance of a mere 0.5 °C.

The special aspect of this heating technology (which is only used on Welltherm infrared heaters) is that more than 70 % of the heater’s heating surface is covered by heating conductors. This results in excellent heat distribution and efficiency. For most other infrared products this value is between 6 % and 23 %.
