Comparison Of Three Kinds Of Heaters

1. resistance heaters heating is the most primitive, so efficiency is also the worst, usually thermal efficiency of only about 70%, a lot of heat into the air.
2. compared to the infra-red heating resistance is a little better, but still a lot of heat into the air, but not infrared itself into the air, but the object to be heated the heat into the air.
3. flying such as solenoid heater is a layer of insulation when wrapped in heated objects, then the magnetic field through the insulating layer directly heating the object itself, so the heat almost without loss of efficiency is the highest, the thermal efficiency is more than 95%. And since the fly like electromagnetic heating heater is heating objects so there is no loss of the heat transfer and energy saving is about resistance heating 30%-70% under the same conditions, characteristics of infra-red heaters because the heat and electromagnetic heating can not do a detailed comparison, but gives the temperature calculation should fly under the same conditions as electromagnetic heating infrared heating energy savings of more than 20%.
