ST Energy Co., Ltd.

Just as we do not recognize the value and importance of our dearest families and friends taking them for granted, we Koreans have not been able to appreciate those of Ondol, Korean underfloor heating system, as we have been living with it for so long. This is, however, what we miss most when we live abroad, and unfortunately, installing Ondol system in a foreign country has not been as easy as buying food or clothes.  

So we have paid our attention to the advantages of Ondol which has kept Korean rooms warm for about two thousand years. And we have finally been able to make it easy to use for everyone in the world. For your convenience and health, we have invented a heating bed and sauna with our own special technology.
Here is a heating system that is usable anywhere in the world, very easy to install, and trouble-free. We promise to do our best to keep developing the best heating system for your happy and healthy life.
