Features of Product

1. Two parallel heating elements provide high efficiency than one.
2. Pipe is filled with magnesia (purity is 95% up) and that spread the heat 2 times faster than water.
3. This model consists double pipe structure (inner pipe and outer pipe) which quickly spread of 2nd heat.
4. Outer pipe is made of Polypropylene pipe and allows semi-permanent long life because it is free from corrosion cause on cement and water and protects from electric leakage.
5. The heating element - spring type (not straight type)- achieves non electromagnetic waves. And two parallel heating elements allow non electromagnetic waves especially. This is only one electric ondol in Korea that has double pipe structure of sheath type with non electromagnetic waves and gained the patent.
6. Two parallel heating elements provide high heating efficiency and diameter is 20Ø which is twice bigger compared to other company’s products. This is only one electric ondol in Korea that heating is available with 400W per 3.3㎡.
