Starting with WEALTH in 2005, we became more active with THOTH, a spin-off company in 2012, and successfully supplied a total of 800 rooms, including 400 shower rooms and 400 rooms excluding hallways, to Daelim Industrial (now DL E&C). Current global climate change cannot be solved by any one country or region reducing greenhouse gas emissions. We face an urgent need to significantly reduce net greenhouse gas emissions. Greenhouse gases are emitted from industrial processes and energy use, primarily electricity use. One air conditioner consumes the same power as 30 fans, and one electric range consumes the same power as 50 electric blankets. Therefore, the number of home appliances should not be reduced uniformly. The black body radiant ondol produced domestically is an eco-friendly product that fundamentally reduces greenhouse gas emissions by halving power consumption from the beginning of heating. The product has a humidifying function, which reduces colds and improves respiratory diseases such as asthma. Korea Black Body Radiant Ondol will do its best to improve human health and quality of life. thank you
