4. The other factor is that since the warm air goes up, and here the heater first heats the object (human), the energy loss will be much lower in comparison with the standard convective heater. Far infrared heater does NOT carry up air dust currents that creates breathing problems for people with breathing diseases (like asthma, bronchitis, allergy etc.) due to its characteristic of having no contact of the heating element with the air (it is hermetically covered with film), that is why, it does not need oxygen to heat (as many standard heaters do). So, you have clean air in the room and do not have to open the windows often in order to let in the oxygen, which, of course, will tend to the heat loss.



5. The temperature on the surface is max. +70C, and when the surface is touched by a hand, the wire there becomes colder, and when the hand is withhold, within several seconds it gains the same temperature. So, when touched, the heater does not burn, that is why it is safe even for children (though we still do not recommend to use the heater for children without supervision of adults).



6. The carbon fiber we use was developed in former USSR for space technologies and till this moment we couldn’t find anywhere in the world any other carbon fiber that is produced widely and on stable basis with similar characteristics. These characteristics affect the infrared wave and the life-time of the fiber and therefore, the life-time of the heater. There are also many Far infrared heaters that are really successful and good quality, but most of them use carbon paste (fluid) for the heating element. This is a very good solution, but the only thing is that it needs a hard frame (metal, ceramic, stone etc.), which is of course, dramatically enhanced the cost of the product, sometimes, it makes the final cost 2-3 times higher. In our case, we found a way to avoid using the hard frames like that and the heater is packed in a special film (the film melting point is +120C and burning point is +250C. The heater has built-in security, overheating protection that works automatically in case if by any reason the temperature will exceed +85C).
