Principle of infrared heating

The principle of infrared heating is inspired by nature


Only the warming rays of the sun have enabled life on our planet. The warmth we feel in the sunlight, but also in front of a fireplace or a stove, is infrared radiation. On a winter day the cool air does not bother us as long as the warming rays of the sun reach us directly. Infrared radiation overcomes the distance between the sun and the earth nearly without losses and turns into heat once hitting the surface. In contrary to UV or X-ray radiation particularly the long-wave infrared-C range has a positive impact on human well-being.

Since the body, mainly our skin, absorbs the infrared waves directly, it immediately establishes a feeling of well-being. As a result, rooms which are heated by infrared heating systems feel comfortable at an indoor air temperature of approximately 2°C lower than rooms heated by conventional convection systems, which helps to reduce energy consumption and heating costs significantly.

Conventional heating systems warm up the air by applying the principle of convection (i.e. radiators, convectors, air-conditions, etc.). radiator

Convection currents heat up the air causing it to increase in the room before colder winds in the upper area of a room cool it down and make it decrease to the bottom of the room again. This loop is repeated and induces uncomfortable air circulation in the room causing air temperature difference between floor and ceiling and distribution of dust, smoke, noise, smell as well as emission of CO2. As a result colder temperatures on the bottom of the room often cause people to turn up the heating systems to a maximum, drying out the air in the room. As a result of the lower temperatures down the floor of the room we get аn unpleasant effect – “cold legs”, which forces us to increase the temperature in the room, respectively, to increase the performance of the heating appliances, and to increase our monthly electricity bill. The increase in the average temperature of the room tends to dry the air in the room. Conventional heating systems lose a significant amount of energy (heat) in the transfer of heat from the appliance which generates it to the room in which the heat will be used. Additionally, conventional heating systems lose a considerable amount of energy through burners, chimneys, boilers etc. In most cases it is necessary tubing for the transferance of heated water from the boiler, fireplace, stove, etc. to the radiator that will warm the room. The longer is the tubing system, the bigger are the heat losses. Convection appliances use an air to transfer the heat, and form a strong air currents that require a higher room temperature for feeling of comfortable warmth. By heating with air conditioning, fan or radiator you feel  heat comfort at 25 ° C-26 ° C. In most cases a temperature sensor in the air conditioner is high up in the indoor unit, which further requires a higher set temperature because as we know, the warmth moves upward. In this case, if the average ambient temperature should be 23 ° C-24 ° C, the air conditioner must be set at 28 ° C-29 ° C.

Same as the sun does, Redsun infrared panel heaters emit invisible infrared waves which directly warm up objects (floors, walls, furniture, etc.) and bodies in a room.

These objects absorb and reflect the energy until an even temperature distribution in the room has been established. The air remains at a consistent temperature and humidity within the room feels comfortable. Through the fact that the surface temperature of the objects in the room is higher than the surrounding air condensation or mould creation can not occur. Hard and solid bodies and objects heat up slower than air, but much slower cool too. The initial heating of the solid objects may take up to 1-2 days but then the required operation time of the infrared panels significantly decreases. When all hard surfaces in the room are heated then the air in the room heats very quickly and easily too. Already heated radiant, all solid surfaces in the room act as a heater. The air remains with substantially uniform temperature along the entire height of the room. The difference between the temperatures down (floor) and up (ceiling) is within 2 ° C-3 ° C and the effect of “cold legs” reduces to zero. The most efficient performance of heating with infrared panels is registered with their installation on the ceiling in the room. When the radiant infrared appliance is mounted on the ceiling, it has full “visibility” to the whole room, it heats mainly the floor and the floor warms the air up from bottom. The way of heating makes you feel like you use underfloor heating. After airing the room which is heated with infrared radiators, returning the desired room temperature becomes significantly faster because all surfaces in the room are warm and as the air warms up very easily and quickly, it takes only about 10-15 minutes. Thanks to the fact that the surface temperature of all objects and bodies in the room is about 1 ° C higher than the temperature of the room air, the possibility of condensation and  mold in the room decreases drastically. No need of tubing, pumps, valves, air filters, external body and whatever related to conventional heating appliances.
