SUNJOY is a radiant heating system where you can have the same warm feeling of the sunlight. Not like the convection heating which uses dry hot air, SUNJOY provides pleasant heating environment. We often experience that the temperature feels different between the sunshine and the shade even if the measured temperature is the same. This is because in the sunshine, the sun's radiant heat is directly transmitted to our body. In addition, the radiant heating transmits heat quickly to every corner of the room.
