1. It is the advanced heating technology to increase the heating efficiency using special heat medium and expansion pressure by the hear generation of the insulation wire inside the closed X-L pipe without floor heating means such as boiler, etc.

2. With the core boiling effect, you can save 70% or more heating cost compared to the oil hearing of the same area.

3. Long time heating is possible with small energy by the heat storing action of the heat medium and plaster layer filled in the pipe.

4. A/S can be done by only opening the check box without damaging the finish material.

5. With the adoption of expansion pressure absorbing device inside the pipe, it prevents the burst of X-L pipe and leakage of liquid, and with the insertion of the natural material that prevents heat storage and freezing, freeze and burst is prevented down to -20 degrees.
