The Heating Industry is dividing House, Agriculture and Industry Type House heating type is distinguish dry system using radiate, and wet system using Heat Flow. Korea is adopted by Heatflow system , and the other country is adopted radiate system. Agriculture heating type mainly is used by Vinyl house and it&＃39;s main fuel is coal and petroleum. Environment destroy is happening very serious by Earth-warming , so many country limit using fossil fuels. -Technical description - Heat Flow Heating System : As the floor heating system is operated by electricity, it provides pleasant heating and energy effective feature compared to oil use and existing electric heating system, replacing existing electric ondol panel and heating methods. Everybody with little knowledge is able to install it easily at low cost since the only thing the operator has to do is to lay adiabatic material, Skysun and finishing material on the floor in order. It attains 80~90% of the set-up temperature in 1 minute and 100% in 5 minutes. It saves heating cost up to 75% as the heat is generated 100% from all the product area.- Picture Frame Heater : This is used for both decoration and heating purposes. Emitting far infrared ray(8~15micrometer) is good for our health as well as pleasant heating without space restriction. Moreover, it saves electricity expense and does not have any fire nor harmful gas risk resulted from using fossil fuel. It can be installed in ordinary house, commercial building, hotel, hospital and other heating required places with ease.- Dry Sauna System : As a dry sauna applied by far infrared ray and anion, naos dry sauna system is installed for both home and public use. The system is superior in thermal efficiency, medical effect, far infrared ray emission rate to other dry sauna systems. Also, It never burns panel, which is major problem of existing dry sauna system and increases its lifetime double.
