Traditional heating effects

• the hot air raising towards the ceiling and circulate the dust and the dust mite in the room
• the circulating air takes up more moisture resulting subsidence wich could cause mustiness
• the heat transmission of the air is low, so the wall temperature is lower than the air temperature
• the thermal conducton value increases
• after airing the room get cold and energy consumption increases
• the temperature difference between the floor and the ceiling is significant (can reach 8-10˚C)
• negative physiological effect: slowing blood circulation, dust allergy
