Power-Saving heat radiation pipe (CYES boiler and closed hot water pipe)
Characteristics
1.Due to use of electricity, clean energy, it is eco-friendly without generating any emissions while being used., 
2.As surface temperature of heating wire does not rise above 70℃, no device to prevent overheating due to thermal expansion is necessary, thus safe.
3.A system which does not affect durability life of hot water pipe due to low watt density.
4. No failure rate, trouble-free without mechanical device.  
5. Technology to use hot water circulation heating pipe as closed heat radiation 6. Uninterrupted heating despite power disconnection .

Expected Effect
Via major heating wire (wire No.1) alone, heating is provided according to a temperature set by an automatic temperature regulator. In case the major heating wire is disconnected by accident, a bimetal in spare wire connected to a power line works automatically, enabling uninterrupted heating before repair or maintenance is over

Use
